HTTP Status 404 – Not Found Docker Tomcat Image

How to fix the HTTP Status 404 - Not Found Error for the Docker Tomcat image? 

While trying to pull Tomcat image from Docker Hub to install Tomcat server on Amazon EC2 Linux virtual machine by executing the below commands in the terminal:

docker pull tomcat 

docker run --name tomcat-server -p 8080:8080 tomcat:latest

 

And when you open the browser by visiting http://container-ip:8080, you might have noticed the HTTP Status 404 – Not Found. 

HTTP Status 404 – Not Found

---

Type Status Report

Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

---

Apache Tomcat/9.0.36

You might have started thinking that you have done some mistakes while installing the Docker image. If you are thinking in those lines, then you are wrong. This is no error and it was designed to behave like this due to security concerns raised by the Docker community.  You can find this information on security on the Tomcat image official documentation in DockerHub

The information which is provided on Tomcat image official documentation in DockerHub isn't helpful for the people who have the beginner level knowledge of Docker.  

Based on the community request, Webapps folder is moved to the webapps.dist folder, which means webapps folder is empty and there are no files to serve on the browser. That is when you saw the error message The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

To re-enable the webapps, we need to move the files from webapps.dist to webapps. Here are the steps to run to make sure that the tomcat server is up and running without any issues. Please run the below commands step by step: 

docker pull tomcat:latest

 

docker run -d --name mytomcat -p 8080:8080 tomcat:latest

 

docker exec -it mytomcat /bin/bash

 

mv webapps webapps2

 

mv webapps.dist/ webapps

 

exit

Hope this information helps!

How to pull the hashtags from the RSS Feed URL

This article is about automating the manual process of copying the hashtags from a given RSS feed URL and pasting on social media such as Facebook. This article is divided into three parts:

1. How to pull the hashtags from the FeedBurner
2. How to get the Access Token for Facebook Graph API?
3. How to publish the posts on Facebook page via Python Scrip

In this article, we will learn how to pull the hashtags from FeedBurner, In order to get started with it, we need to install Feedparser python library. To install the Feedparser libraries, use below commands in the command prompt

pip install feedparser

Once you have installed feedparser, you can use the below code which extracts the title, link, hashtags using the following script. Copy the below code and save it with .py extension, execute in command prompt

import feedparser
import re
NewsFeed = feedparser.parse("http://feeds.feedburner.com/Especiallysports")
for item in NewsFeed.entries:
    print('Post Title :',item.title)
    print('Post Link :',item.feedburner_origlink)
    result = re.findall(r"#(\w+)", item.summary)
    aces = ["#" + suit for suit in result]
    hashtags = ' '.join(aces)
    print('Post hashtags :',hashtags)
   

The output should like this:

By default, the above script will throw 25 posts, to display only first 3 articles, you can use the below script

import feedparser
import re
count=0
NewsFeed = feedparser.parse("http://feeds.feedburner.com/Especiallysports")
for item in NewsFeed.entries:
    print('Post Title :',item.title)
    print('Post Link :',item.feedburner_origlink)
    result = re.findall(r"#(\w+)", item.summary)
    aces = ["#" + suit for suit in result]
    hashtags = ' '.join(aces)
    print('Post hashtags :',hashtags)
    print('')
    count=count+1
    if count>2:
        break

Output:

We have successfully able to pull the required data from the Feedburner to post it on the Facebook page. Let's move on and see how we can post on the Facebook page. In the next post, you will learn How to get the Access Token for Facebook Graph API?

How to get the Access Token for Facebook Graph API?

In this How to pull the hashtags from the FeedBurner post, we have extracted the hashtags that we are going to post on the Facebook page, and in this post, we need to generate an access token for Facebook Graph API. Please follow the instructions to get started with it:

How to get the Access Token for Facebook Graph API?

1. Go to Facebook Graph API Explorer and Click on Login  
2. Create a new app or continue with the already created app. 
   
   
3. On the right side, you should see the newly created Facebook App, if you want to work with a different app, you can switch the apps by choosing from the dropdown list. In my case, I want to work with Especiallysports app.  
   
   
4. Next to Facebook App, you can find an option that says, User or Page, this option lets us choose whether we want to work with User profile, page profile, particular App. Please note, the tokens are issues at different levels, user level, page level, app level.  In my case, I would like to work with pages, I'll choose the Get Page Access Token. When you select the above option, a dialog box appears asking for the consent. Just click on the continue and provide the necessary page access and required permissions for that. 
5. Once step 4 is completed, you'll find the pages in the dropdown list where you can able to choose the page that you want to work with. In my case, I want to work with Especiallysports page, therefore, I have chosen that. 
   
6. Just below User or Page option, you can find add permissions option, which lets you can add additional permissions.  
   
   
7. Click on Generate Access Token and copy the token 

Now, its time to test if we have access to our Facebook data. On the left side, you see an option where you can see and perform operations such as GET, POST, DELETE. Let's get started with getting the data. 

When you click on the submit button, you should see the id and name of the page. 

To retrieve the page posts, you can change URL to me/posts

To retrieve a specific page post, you can change URL to /Postid, as shown in the below URL.

To publish a post on the Facebook page, you can use below, A Facebook page post will be created on the Facebook page. You can refer to the below screenshot:

Here is the screenshot of the Facebook page post.

To delete this post, you can use DELETE operations when the post is deleted, it returns success message as shown in the below screenshot.

In the next article, you can learn how to connect programmatically and perform various operations such as retrieving, publishing, and deleting the posts using Python script. 

How to publish the posts on Facebook page via Python Script

In this How to pull the hashtags from the FeedBurner post, we have extracted the hashtags that we are going to post on the Facebook page, and in this post, you have learned How to get the Access Token for Facebook Graph API? we have generated the access token to publish the post on the Facebook page. 

In this article, you will learn how to retrieve, publish, and delete the posts from the Facebook page.

In order to perform various actions on Facebook, there is a popular unofficial Python 3rd party library called Facebook-SDK which is a prerequisite for connecting to Facebook. To install the Facebook-SDK python library, use below commands in the command prompt as shown in 

pip install facebook-sdk

Since the Facebook-SDK library is already installed on my computer, therefore, I'm seeing the requirement already satisfied, In your case, you should see the installation complete and success message. 

Copy the below code and save it with .py extension and replace the access token with your token.

Working with Blogger API v3 using python for beginners via Oauth 2.0

Hi Guys,

I’m going to show you how to connect Google blogger API using python. I had a requirement of creating more than 100 plus blog pages by duplicating the existing blog page. Below is the below breakdown:

1. Retrieving the blog page from blogger
2. Extract and copy the content from the blog page
3. Create a new blog page and insert the extracted content

The main reason for posting this article, I couldn't find the right tutorial that can help in understanding the code in one go and it took a lot of time to accomplish this task. I hope this tutorial will help you.

There are two ways, you can interact with your blog using python:

• Oauth 2.0
• API key

In this blog, I will show how we can interact with blogger API using python with Oauth 2.0. It is a recommended way to interact with your Google API resources. The first step will be creating project and credentials

In order to access your enabled APIs(i.e, Blogger API in our case), we need to create credentials, these credentials must be kept in secret and otherwise, someone may steal your keys, you will end up paying for Google once the quota is exceeded. Please follow the below steps to create credentials for your project. Steps are in the below, video you can use it for creating client_secret.json file.

1. Open the Google API Console Credentials page.
2. Click Select a project, then NEW PROJECT, and enter a name for the project, and optionally, edit the provided Project ID. Click Create.
3. On the Credentials page, select Create credentials, then OAuth client ID.
4. You may be prompted to set a product name on the Consent screen; if so, click Configure consent screen, supply the requested information, and click Save to return to the Credentials screen.
5. Select Web Application for the Application Type. Follow the instructions to enter JavaScript origins, redirect URIs, or both.
6. Click Create.
7. On the page that appears, copy the client ID and client secret to your clipboard, as you will need them when you configure your client library. 

After creating the project, you need to enable the Blogger API v3 in the Google API console. Please follow the below steps:

1. Navigate to APIs & Services
2. Search for Blogger API
3. Enable it

Your client-secrets should look like below:

{"web":{"client_id":"814572920180-5lua2cehvonjidhjck5sql4gf2roavu5.apps.googleusercontent.com","project_id":"wordpress-learning-203906","auth_uri":"https://accounts.google.com/o/oauth2/auth","token_uri":"https://oauth2.googleapis.com/token","auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs","client_secret":"R0B_Ayy6A-PBhRIJ5nhUmFOe","redirect_uris":["http://localhost:8090/"]} 

Note, after downloading the client_secret.json file, make sure to change the name. The name should be renamed as client_secret.json and place it in the folder wherever your current project is. My project folder is "E:\blogger api\python-blogger"

Open the command prompt and run as an administrator, navigate to the project folder, mine is "E:\blogger api\python-blogger" and install below libraries:

• pip install --upgrade google-api-python-client
• pip install httplib2
• pip install oauth2client

After installing libraries, copy the below the code and save it in your project folder and save the file with .py extension,

import httplib2
from oauth2client.client import flow_from_clientsecrets
from oauth2client.file import Storage
from oauth2client.tools import run_flow
from googleapiclient import discovery
CLIENT_SECRET = 'client_secret.json'
SCOPE = 'https://www.googleapis.com/auth/blogger'
STORAGE = Storage('credentials.storage')
# Start the OAuth flow to retrieve credentials
def authorize_credentials():
# Fetch credentials from storage
    credentials = STORAGE.get()
# If the credentials doesn't exist in the storage location then run the flow
    if credentials is None or credentials.invalid:
        flow = flow_from_clientsecrets(CLIENT_SECRET, scope=SCOPE)
        http = httplib2.Http()
        credentials = run_flow(flow, STORAGE, http=http)
    return credentials
credentials = authorize_credentials()
print(credentials)

*Note: please take care of the indentation, if you have issues copying from here, you can check using here
https://github.com/ImRaj90/Python-blogger-api-oauth2/blob/master/python-blogger-testting.py

After saving it, run the python program, then you will see a browser will ask to login into your Google account and request to grant the permission. Once you have accepted it. You should see the message authentication successful, message on the command prompt

Once the authentication is successful, credentials.storage file will be created in the project folder, please refer to the below screenshot.

Credentials.storage file contains all information required for authentication, which prevents the program from authenticating again every time we are running the program. This is one time set up.

Then, create a function as below:

def get_pages_from_jobs(blogId):
    credentials = authorize_credentials()
    http = credentials.authorize(httplib2.Http())
    discoveryUrl = ('https://www.googleapis.com/blogger/')
    service = discovery.build('blogger', 'v3', http=http, discoveryServiceUrl=discoveryUrl) 

*Note: please take care of the indentation, if you have issues copying from here, you can check using here

https://github.com/ImRaj90/Python-blogger-api-oauth2/blob/master/python-blogger-testting.py

At the end of the program, we need to call the above function(below highlighted in red). After the function, the code should look like this:

import httplib2
from oauth2client.client import flow_from_clientsecrets
from oauth2client.file import Storage
from oauth2client.tools import run_flow
from googleapiclient import discovery
CLIENT_SECRET = 'client_secret.json'
SCOPE = 'https://www.googleapis.com/auth/blogger'
STORAGE = Storage('credentials.storage')
# Start the OAuth flow to retrieve credentials
def authorize_credentials():
# Fetch credentials from storage
    credentials = STORAGE.get()
# If the credentials doesn't exist in the storage location then run the flow
    if credentials is None or credentials.invalid:
        flow = flow_from_clientsecrets(CLIENT_SECRET, scope=SCOPE)
        http = httplib2.Http()
        credentials = run_flow(flow, STORAGE, http=http)
    return credentials
credentials = authorize_credentials()
print(credentials)
def get_pages_from_jobs(blogId):
    credentials = authorize_credentials()
    http = credentials.authorize(httplib2.Http())
    discoveryUrl = ('https://www.googleapis.com/blogger/')
    service = discovery.build('blogger', 'v3', http=http, discoveryServiceUrl=discoveryUrl)
    
get_pages_from_jobs(xxxxxxx)

*Note: please take care of the indentation, if you have issues copying from here, you can check using here

https://github.com/ImRaj90/Python-blogger-api-oauth2/blob/master/python-blogger-testting.py

After that, you can copy the below code, you can copy the respective code for corresponding actions:

1. For users

Add the below code(highlighted in yellow) just below  service = discovery.build('blogger', 'v3', http=http, discoveryServiceUrl=discoveryUrl)

users = service.users()
# Retrieve this user's profile information

Technology is growing day by day. If you are adjusted to today then you are outdated tomorrow, this is the trend in the technology field. In the last century computers, mobiles were miracles, but today it's our part. Even a person with no eyes will be happier than a person without mobiles today. Charles Darwin in the theory of survival said that the person who is adaptive to change is the one who survives. This worked out today. New, innovative, creative inventions are invented every day.

5G is out and you can have access to it next year. In every field, technology is used as a tool to develop the results. From smartphones to smart heaters, from wire to wireless everything has changed. The transportation industry is using mobile apps to improve sales. These tollgate guys are using the fast tag to make it fast. VISA is using the swipe and pay option to reduce the queue line. Payments became online, sales became online and what can we expect next?

Face recognition

Face recognition means digital beings recognizing our faces. You already know that this feature is on your mobile right? (Not in all mobiles). But face recognition means not this one. It's like a mobile thing but more advanced. This is the testing stage and you can expect this feature to roll out at the beginning of 2021.

How can this feature help us? Are you always tired of showing your ID Card to the timekeeper or Are you tired of checking in those biometric machines? This helps out here. You can just walk into your office without those nuisance. Only this? Na Na. Still more, you can have advanced security to your digital world. Fingerprints may go and face check may come in 2021.

Smart newspaper

Harry Potter, a well-known name to us. If you are a Harry Potter fan, you must have watched the Harry Potter prisoner of Azkaban. In the movie, you can see characters, text, pictures rolling out in the newspaper. In the Harry Potter world, it's fantasy and in the real world, it's a smart newspaper. Yes, you heard right, a smart newspaper.


It's different from the e-newspaper. If you read a newspaper on an electronic gadget like laptops and mobile, then it's an e-newspaper and if the newspaper itself is a gadget, then it is a smart newspaper. What's the advantage of it? You can gain a lot. You can get updated news within a short span. You can get a video played in a smart newspaper unlike pictures in traditional newspapers. It gives a lot of comfort to your eyes which reduces the chance of myopia. You can check your favorite news easily. The main advantage is it's eco-friendly. You can save a lot of paper and can control global warming because of it. You can even hear the news from it. We can expect this feature to be tested at the end of 2021. The main question is whether it's online or offline?
