How do I upload both form data and multiple files from my android app, using HTTPURLConnection to my server, where I am using PHP? -
i have android application sending 1 or more zip files server. i'd send additional form data along files, because form data used determine disposition of files.
i've been able upload files using multi-part content-type, can't seem php on server side see both form data , files.
what i'd know how send form data , list of files server using httpurlconnection on android side , php on server side.
i believe problem related content-type , content-disposition. i'd appreciate if point me @ definitive example, or explain i'm doing wrong.
thanks taking time @ problem.'
here's latest, revised android code:
string postdriverupload(file[] filelist) { httpurlconnection connection = null; dataoutputstream outputstream = null; string tag = tag + "postdriverinfo()"; url url = null; string result = ok_to_continue; string targeturl = server + "/upload.php"; try { url = new url(targeturl); } catch (malformedurlexception e) { result = "error: [" + targeturl + "] can't parsed url."; log.e(tag, result, e); return result; } try { connection = (httpurlconnection) url.openconnection(); } catch (ioexception e) { result = "error: ioexception."; log.e(tag, result, e); return result; } // allow inputs , outputs connection.setdoinput(true); connection.setdooutput(true); connection.setusecaches(false); // enable post method try { connection.setrequestmethod("post"); } catch (protocolexception e) { result = "error: protocol exception."; log.e(tag, result, e); return result; } connection.setrequestproperty("connection", "keep-alive"); connection.setrequestproperty("content-type", "multipart/form-data;boundary=" + boundary); // encode driver username list<namevaluepair> namevaluepairs = new arraylist<namevaluepair>(); try { namevaluepairs.add(new basicnamevaluepair("username", driver .getusername())); log.d(tag, "encoded username='driver' is: " + encodedata(namevaluepairs)); // create output stream send data server outputstream = new dataoutputstream(connection.getoutputstream()); writeboundary(outputstream); outputstream .writebytes("content-disposition: form-data; name=\"username\" " + eol + eol); outputstream.writebytes(driver.getusername() + eol); writeboundary(outputstream); // starting files part outputstream .writebytes("content-disposition: form-data; name=\"files\" " + eol + eol); outputstream.writebytes("content-type: multipart/mixed; boundary=" + file_boundary + eol); // adding file parts (file file : filelist) { writefileboundary(outputstream); // write out file string contenttype = string.format( "content-disposition:file; filename=\"%s\"" + eol + "content-type: application/x-zip-compressed", file.getname()) + eol + eol; log.d(tag, "content-type = " + contenttype); outputstream.write(contenttype.getbytes()); } writefileboundary(outputstream); writeboundary(outputstream); outputstream.flush(); outputstream.close(); } catch (unsupportedencodingexception e) { result = "error: unsupportedencodingexception "; log.e(tag, result, e); return result; } catch (ioexception e) { result = "error: ioexception "; log.e(tag, result, e); return result; } // response server (code , message) try { int serverresponsecode = connection.getresponsecode(); string serverresponsemessage = connection.getresponsemessage(); log.d(tag, "response code = " + serverresponsecode); log.d(tag, "response message = " + serverresponsemessage); } catch (ioexception e) { result = "error getting response server."; log.e(tag, result, e); return result; } final stringbuilder out = new stringbuilder(); try { bufferedreader in = new bufferedreader(new inputstreamreader( connection.getinputstream())); string line; while (null != (line = in.readline())) { if (line.contains("error")) { log.d(tag, "httpresponse: " + out.tostring()); result = "error: httpresponse: " + out.tostring(); break; } out.append(line + "\n\n"); } log.d(tag, "httpresponse: " + out.tostring()); } catch (ioexception e) { log.w(tag, "warning: ", e); } return result; } void writeboundary(dataoutputstream out) throws ioexception { final string twohyphens = "--"; out.writebytes(twohyphens + boundary + eol); } void writefileboundary(dataoutputstream out) throws ioexception { final string twohyphens = "--"; out.writebytes(twohyphens + file_boundary + eol); } here's output of logging on android side. can see, key, username , value, rbenjamin, being loaded $_post variable, isn't right past point. delimit next section boundary, seems gobbled value variable 'files'. i'm close, i'm still missing something. (i stripped out of noise in log file below.)

no 1 answered question, found needed here: a www.codejava.net article on sending multipart forms programatically . doctor ordered. article provides class, multipartutility, makes easy upload using httpurlconnection. not answer, it's structured one. had tweak bit android, not much.
