Html5+ajax the key parameter setting of the original zoning block upload file

Processdata:false

This is a parameter of Jquery.ajax. The default value is true, which means that non-string objects are automatically converted to K1=v1&k2=v2 form, such as an array parameter {d:[1,2]}, which becomes d[]=1&d[]=2 after the server.

To set it to false to upload the Arraybuffer object, the server gets the raw byte stream directly from the Request.inputstream.

W3school Explanation:

true " application/x-www-form-urlencoded " false.

Main code: (the following code is called in the Readasarraybuffer completion event onload of the FileReader async method, this points to the current reader)

$.ajax ('/home/file ',                    {                        this. result,                        ' POST ',                        false ,                         function (res) {                            console.log (res);                        },                        function  (err) {                            console.log (err);                        }                    });

The server accepts the file class content:

var stream = Request.inputstream;

Because only HTML5 have FileReader object, so only HTML5 support JS original zoning block upload file.

The previous article uses the WebSocket original zoning block to upload files in a way that only supports HTML5.

Because the http1.1 default Keep-live property, the connection is not re-established each time it is requested. Therefore, the server can not use the WebSocket scenario, but the client is supported by the HTML5 case, the Ajax original zoning block upload.
