我正在尝试使用HTTPURLConnection将5个字符串值和图像发布到php服务器。获取响应代码为200，响应消息为OK，但发布后的实际响应未获得。以下是我正在使用的代码：
public int sendRprtWithImageToServer(String getImagePath, String strEmailList){
String upLoadServerUri = "My URL";
String fileName = getImagePath;
HttpURLConnection conn = null;
DataOutputStream dos = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
int serverResponseCode = 0;
File sourceFile = new File(getImagePath);
if (!sourceFile.isFile()) {
Log.e("Huzza", "Source File Does not exist");
return 0;
}
try { // open a URL connection to the Servlet
FileInputStream fileInputStream = new FileInputStream(sourceFile);
URL url = new URL(upLoadServerUri);
conn = (HttpURLConnection) url.openConnection(); // Open a HTTP connection to the URL
conn.setDoInput(true); // Allow Inputs
conn.setDoOutput(true); // Allow Outputs
conn.setUseCaches(false); // Don't use a Cached Copy
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("ENCTYPE", "multipart/form-data");
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
conn.setRequestProperty("stringkey1", stringvalue1);
conn.setRequestProperty("stringkey2", stringvalue2);
conn.setRequestProperty("stringkey3", stringvalue3);
conn.setRequestProperty("stringkey4", stringvalue4);
conn.setRequestProperty("stringkey5", stringvalue5);
conn.setRequestProperty("stringkey6", fileName);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"stringkey1\";filename=\""+ stringvalue1 + "\"" + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"stringkey2\";filename=\""+ stringvalue2 + "\"" + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"stringkey3\";filename=\""+ stringvalue3 + "\"" + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"stringkey4\";filename=\""+ stringvalue4 + "\"" + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"stringkey5\";filename=\""+ stringvalue5 + "\"" + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"stringkey6\";filename=\""+ fileName + "\"" + lineEnd);
dos.writeBytes(lineEnd);
bytesAvailable = fileInputStream.available(); // create a buffer of maximum size
Log.i("Huzza", "Initial .available : " + bytesAvailable);
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
// read file and write it into form...
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0) {
dos.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
// send multipart form data necesssary after file data...
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
InputStream is = conn.getInputStream();
int ch;
StringBuffer sb = new StringBuffer();
while ((ch = is.read()) != -1) {
sb.append((char) ch);
}
Log.d("String response ", sb.toString());
// Responses from the server (code and message)
serverResponseCode = conn.getResponseCode();
String serverResponseMessage = conn.getResponseMessage();
Log.i("Upload file to server", "HTTP Response is : " + serverResponseMessage + ": " + serverResponseCode);
// close streams
Log.i("Upload file to server", fileName + " File is written");
fileInputStream.close();
dos.flush();
dos.close();
} catch (MalformedURLException ex) {
ex.printStackTrace();
Log.e("Upload file to server", "error: " + ex.getMessage(), ex);
} catch (Exception e) {
e.printStackTrace();
}
//this block will give the response of upload link
try {
BufferedReader rd = new BufferedReader(new InputStreamReader(conn
.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
Log.i("Huzza", "RES Message: " + line);
}
rd.close();
} catch (IOException ioex) {
Log.e("Huzza", "error: " + ioex.getMessage(), ioex);
}
return serverResponseCode; // like 200 (Ok)
}
任何人都可以帮助我如何传递HTTPURLConnection

我认为你应该使用filebody来获取文件附件本身，另外5个字符串应该嵌入multipart
public JSONObject file_upload1(String URL, String userid, String topic_id,
String topicname, String filelist, List<String> taglist,
String textComment, String textLink) {
JSONObject jObj = null;
// Making HTTP request
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(URL);
FileBody bin = null;
MultipartEntity reqEntity = new MultipartEntity(
HttpMultipartMode.BROWSER_COMPATIBLE);
File file = new File(filelist);
System.out.println("file name" + filelist.get(i));
try {
bin = new FileBody(file);
} catch (Exception e) {
e.printStackTrace();
}
reqEntity.addPart("post_data" + i, bin);
}
for (int i = 0; i < taglist.size(); i++) {
reqEntity.addPart("dtype" + i, new StringBody(taglist.get(i)));
}
reqEntity.addPart("tag", new StringBody("savetopicactivities"));
reqEntity.addPart("user_id", new StringBody(userid));
reqEntity.addPart("text", new StringBody(textComment));
reqEntity.addPart("count",
new StringBody(String.valueOf(taglist.size())));
reqEntity.addPart("topic_id", new StringBody(topic_id));
reqEntity.addPart("topic_name", new StringBody(topicname));
reqEntity.addPart("link", new StringBody(textLink));
httpPost.setEntity(reqEntity);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (Exception e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
json = sb.toString();
System.out.println("json " + json);
try {
jObj = new JSONObject(json);
} catch (Exception e) {
e.printStackTrace();
}
is.close();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// return JSON String
return jObj;
}
