HTTP Post Form Experience record

The format of the post form must not change, especially the format of the data section in the form. Last night's bug is because in the form of the data part of the increase in content-length, the superfluous, resulting in the server received the data in the body of the number of characters (more out of the character is Content-length). Content-length should be assigned in the HTTP header. Hereby record.

In addition, the post form is not compressed or the server is not recognized.

Finally, enclose the form in the correct format:

HTTP HEADER:

Content-type:multipart/form-data; boundary=------uploadboundary------

HTTP Body:

--------uploadboundary------

Content-disposition:form-data; Name= "Shopid"

50000

--------uploadboundary------

Content-disposition:form-data; Name= "Name"

Photo Name (Utf-8)

--------uploadboundary------

Content-disposition:form-data; Name= "token"

--------uploadboundary------

Content-disposition:form-data; Name= "Photo"; Filename= "Whatever.jpg"

Content-type:image/jpg

JPG data

--------Uploadboundary--------

SAMPLE CODE (JAVA):

String CRLF = "/r/n";

String boundary = "--------uploadboundary------";

Bytearraybuffer buffer = new Bytearraybuffer (data.length + 1000);

Post.setheader ("Content-type", "multipart/form-data; boundary=------uploadboundary------");

Shopid

Buffer.append (boundary);

Buffer.append (CRLF);

Buffer.append ("Content-disposition:form-data; name=/"Shopid/");

Buffer.append (CRLF);

Buffer.append (SHOPID);

Name

Buffer.append (boundary);

Buffer.append (CRLF);

Buffer.append ("Content-disposition:form-data; name=/"name/");

Buffer.append (CRLF);

Buffer.append (Name.tochararray ("Utf-8"));

Token

Buffer.append (boundary);

Buffer.append (CRLF);

Buffer.append ("Content-disposition:form-data; name=/"token/");

Buffer.append (CRLF);

Buffer.append (token);

Data

Buffer.append (boundary);

Buffer.append (CRLF);

Buffer.append ("Content-disposition:form-data; name=/"photo/"; filename=/"whatever.jpg/");

bytearrayentity entity = new Bytearrayentity (Buffer.tobytearray ());

Post.setentity (entity);

return entity;
