$ HTTP service

$ HTTP is the Ajax service provided by angular.

It also involves

$ Httpbackend, $ httpprovider,

$ Q (angular promise ),

$ Cachefactory (angular cache mechanism) and so on

 

The first time I used the POST request yesterday, I encountered a tragedy when I went to data after the POST request was rejected by ashx.

I flipped through the source code.

The original problem lies in Content-Type.

Angular's default Content-Type is application/JSON, and we usually use application/X-WWW-form-urlencoded (this is also true for jquery)

  VaR Content_type_application_json = {'content-type': 'application/JSON; charset = UTF-8' }; Headers: {common :{ 'Accept': 'application/JSON, text/plain ,*/*' }, Post: shallowcopy (content_type_application_json ),  //  Shallowcopy is a shallowcopy.  Put: shallowcopy (content_type_application_json), Patch: shallowcopy (content_type_application_json )},  //  Transform outgoing request data Transformrequest :[ Function  (D ){  Return Isobject (d )&&! Isfile (d )&&! Isblob (d )? Tojson (d): D; // data will be processed as JSON}], 

In the case of. ashx, if we call content. request ["key"], we cannot obtain data.

We can solve this problem in the original way.

 
Streamreader reader =NewStreamreader (context. Request. inputstream, encoding. utf8 );StringJSON = reader. readtoend (); // This is data, which is a JSON array.
