Oschina, that's mine too, now put it here, haha
This piece of code can only upload one file at a time ~ ~
Copy Code code as follows:
var path=require ("path");
var fs=require ("FS");
var http=require ("http");
Post Value payload
Var getfield=function (field, value) {
Return ' Content-disposition:form-data; Name= "' +field+ '" \r\n\r\n ' +value+ ' \ r \ n ';
}
File payload
Var getfieldhead=function (field, filename) {
var filefieldhead= ' Content-disposition:form-data; Name= "' +field+ '"; Filename= "' +filename+ '" \ r \ n ' + ' Content-type: ' +getmime (filename) + ' \r\n\r\n ';
return filefieldhead;
}
Get MIME
var getmime=function (filename) {
var mimes = {
'. png ': ' Image/png ',
'. gif ': ' Image/gif ',
'. jpg ': ' Image/jpeg ',
'. jpeg ': ' Image/jpeg ',
'. js ': ' Appliction/json ',
'. Torrent ': ' Application/octet-stream '
};
var ext = path.extname (filename);
var mime = Mimes[ext];
mime=!! Mime?mime: ' Application/octet-stream ';
return MIME;
}
Get bounds Check random string
var getboundary=function () {
var max = 9007199254740992;
var dec = math.random () * MAX;
var hex = dec.tostring (36);
var boundary = hex;
return boundary;
}
Get boundary
var getboundaryborder=function (boundary) {
Return '--' +boundary+ ' \ r \ n ';
}
Field formatting
function Fieldpayload (opts) {
var payload=[];
for (Var ID in Opts.field) {
Payload.push (GetField (Id,opts.field[id));
}
Payload.push ("");
Return Payload.join (Getboundaryborder (opts.boundary));
}
Post data
function Postrequest (opts) {
Filereadstream (opts,function (buffer) {
var options=require (' url '). Parse (Opts.url);
var header={};
var h=getboundaryborder (opts.boundary);
var e=fieldpayload (opts);
var a=getfieldhead (opts.param,opts.file);
var d= "\ r \ n" +H;
header["Content-length"]=buffer.bytelength (h+e+a+d) +buffer.length;
header["Content-type"]= ' multipart/form-data; Boundary= ' +opts.boundary;
Options.headers=header;
Options.method= ' POST ';
var req=http.request (Options,function (res) {
var data= ';
Res.on (' Data ', function (chunk) {
Data+=chunk;
});
Res.on (' End ', function () {
Console.log (Res.statuscode)
Console.log (data);
});
});
Req.write (H+e+a); Log.diy (h+e+a+buffer+d);
Req.write (buffer);
Req.end (d);
});
}
Reading files
function Filereadstream (opts, FN) {
var readstream = Fs.createreadstream (opts.file,{flags: ' R ', encoding:null});
var chunks=[];
var length = 0;
Readstream.on (' Data ', function (chunk) {
length + = Chunk.length;
Chunks.push (chunk);
});
Readstream.on (' End ', function () {
var buffer = new buffer (length);
for (var i = 0, pos = 0, size = Chunks.length i < size; i++) {
Chunks[i].copy (buffer, POS);
POS + chunks[i].length;
}
fn (buffer);
});
}
Various settings
var opt={
"url": "Http://xxxx.xx",//url
"File": "00.jpg",//File location
"param": "File",//Files upload field name
' field ': {//remaining post fields
"Client": "1",
"title": "OK"
},
"Boundary": "----webkitformboundary" +getboundary ()
}
Postrequest (opt);
/*
------webkitformboundaryuzkmkaovuuysq1dt\r\n
Content-disposition:form-data; Name= "File"; Filename= "00.jpg" \ r \ n
Content-type:application/octet-stream
\ r \ n
\ r \ n +file\r\n
------webkitformboundaryuzkmkaovuuysq1dt\r\n
Content-disposition:form-data; Name= "FieldName"
\ r \ n
\ r \ n +value\r\n
------webkitformboundaryuzkmkaovuuysq1dt--
*/
The final comment is the standard format "\ r \ n" represents the actual string, in order to look comfortable, also visually adjust
