httpclient 4.3 post form with parameters, submit file/binary data

HttpClient HttpClient = Httpclients.createdefault (); HttpPost HttpPost = new HttpPost (URL); Multipartentitybuilder Mentitybuilder = Multipartentitybuilder.create ();//byte[] Postbodymentitybuilder.addbinarybody (Postname, postbody);//Submit file//file files = new file ("test");// Mentitybuilder.addbinarybody ("name", file), Mentitybuilder.addtextbody ("name", "Value"), Httppost.setentity ( Mentitybuilder.build ()); HttpResponse responce = Httpclient.execute (HttpPost);

Not written as interface: can be written directly together

Httpentity reqentity = Multipartentitybuilder.create (). SetMode (httpmultipartmode.browser_compatible). AddPart (" Multipartfile ", bin). Addpart (" userid ", UserID). Setcharset (Charsetutils.get (" UTF-8 ")). Build ();

Without parameters: The specified entity can be defined directly

File File = new file ("Somefile.txt"); Fileentity reqentity = new Fileentity (file, Contenttype.create ("Text/plain", "UTF-8")); byte[] B; bytearrayentity entity = new Bytearrayentity (b);

Here are the interfaces I define myself:

/** * Http request:post * * @param URL * @param postbody (Byte) * @param postname * @param params * @param heads * @param TimeOut (Millisecond) * @return String of request result */public static string postfile (string URL, byte[] postbody, Strin  G Postname, Map params,map heads, Integer timeOut) throws Httperrorexception {String restr = ""; try {HttpClient HttpClient = Httpclients.createdefault (); HttpPost HttpPost = new HttpPost (URL); Multipartentitybuilder Mentitybuilder = Multipartentitybuilder.create (); Mentitybuilder.addbinarybody (PostName, Postbody); if (params! = null) {//Text paramsfor (Entry e:params.entryset ()) {Mentitybuilder.addtextbody (E.getkey (), e.g Etvalue ());}} Httppost.setentity (Mentitybuilder.build ()); if (heads! = null) {//General requirements プロパティを set しますfor (Entry e:heads.entryset ()) { Httppost.addheader (E.getkey (), E.getvalue ());}} Set Timeoutrequestconfig Requestconfig = Requestconfig.custom ().
