java - Using MultipartEntityBuilder to upload files -


i have existing java code upload files (as byte arrays) box.net, , thought upgrade code apache httpclient 4.4. however, has been proving little harder expected. here working legacy code:

httppost postmethod = new httppost(url); multipartentity multipartentity = new multipartentity(); (namevaluepair parameter : parameters) {     string parametername = parameter.getname();     string parametervalue = parameter.getvalue();     stringbody valuebody = new stringbody(parametervalue, contenttype.multipart_form_data);                         multipartentity.addpart(parametername, valuebody); }  iterator iterator = bytearrayhashmap.keyset().iterator(); while (iterator.hasnext()) {     string key = (string) iterator.next();     byte[] bytearray = bytearrayhashmap.get(key);     multipartentity.addpart(key, new bytearraybody(bytearray, key)); }  postmethod.setentity(multipartentity);

and here new code:

httppost postmethod = new httppost(url); multipartentitybuilder multipartentitybuilder = multipartentitybuilder.create(); (namevaluepair parameter : parameters) {     string parametername = parameter.getname();     string parametervalue = parameter.getvalue();     stringbody valuebody = new stringbody(parametervalue, contenttype.multipart_form_data);                         multipartentitybuilder.addpart(parametername, valuebody); }  iterator iterator = bytearrayhashmap.keyset().iterator(); while (iterator.hasnext()) {     string key = (string) iterator.next();     byte[] bytearray = bytearrayhashmap.get(key);     multipartentitybuilder.addbinarybody(key, bytearray); }  postmethod.setentity(multipartentitybuilder.build());

when run new code, server complains of missing parameter. using multipartentitybuilder correctly?

in case stumbles across question, able solve updating addbinarybody call set contenttype follows: multipartentitybuilder.addbinarybody(key, bytearray, contenttype.default_binary, key);
