Examples of JSON parsing / generation and http requests in various languages

0. jQuery (in Browser, all the hard stuff is handled)
1. NodeJS (Best HTTP and JSON support)
2. Ruby
3. Python
4. GoLang
5. luvit (lua)
6. C#
7. Java
8. curl (exec from any language)
9. bash
10. C

ProTip: Use an Application Language (NodeJS, Python, Ruby) to do all of your HTTP / JSON work coupled with some sort of message passing (such as packing a struct) if you need to use a Systems Language (C, Java, C#). Or just do it all in Go. That would be the best language.

The parser you choose MUST be configureable meet the following criteria:

• IGNORE unexpected and unused fields (new fields may be added at any time)
• ACCEPT null as a non-value for any field type

Additionally:

• when a number is encountered where a string was expected, the number should be treated as a string
• if an expected field does not exist, it should be treated the same as if the value were null

The eventual goal is to have examples for all of the following in each language:

• HTTP GET request
• HTTP POST request
• JSON parsing (decoding / deserializing)
• Iterating over objects and arrays
• JSON stringifying (encoding / serializing)
