Writing a simple web service in python what is the main

In the latter case, I don't want to tell clients to cache my feed for weeks at a time, because then when I do actually post something, people may not read it for weeks because they're respecting my cache headers which said don't bother checking this feed for weeks.

Now let's look at what the server sent back in its response. Python comes with such a library called urllib2 because it's a replacement for an earlier library called urllibbut it exposes a lot of plumbing that most people never want to care about.

The Best Way to Learn Python

Well, it made me finally understand the by-reference versus by-value that I found so ambiguous in other languages. Technically, the important thing is what the headers don't say; the Cache-Control header doesn't have the private keyword, so this data is cacheable by default.

Then it's up to us to decompress the data. Code gets more terse. But the http headers said that this data could be cached by public caching proxies. Value - Can be a string in double quotes, number, or true or false or null, or an object or an array.

Newly added was proper WSDL consumption of complex types into python classes. But for cases where server and client are developed together it saves a lot of trouble. Instead of returning task ids we can return the full URI that controls the task, so that clients get the URIs ready to be used.

If you want to skip all Python specific deployment steps, you can create this empty file: Well, we are done with the functionality of our service, but we still have a problem. The use of whitespace ensured my code was organized coherently into tidy little blocks.

If we run it and send a request from a browser for http: He worked as a software engineer for Cloudera following their acquisition of Datapad in This is used when submitting data via web forms, when uploading files, and so on.

It combines this with the path provided in the URL which the library automatically puts in self. With API's applications talk to each other without any user knowledge or intervention.

If you don't have virtualenv installed in your system, you can download it from https: Python is not a flowery language.

As soon as we find the right case, we let it handle the request and break out of the loop. Now let's write the second version of the GET method for our tasks resource. Each socket is one end of a point-to-point communication channel, just like a phone is one end of a phone call.

As we can see, when we request the Atom feed, the urllib.External links. Python Package Index (formerly the Python Cheese Shop) is the official directory of Python software libraries and modules; ActiveState O'Reilly Python Cookbook contains hundreds of.
