我是 android 的新手，在 android 中上传图片时遇到问题。我已经尝试找到示例但没有运气:
我说错了:
这是我的代码:
我有一个名为 "images" 的数组，其中包含我要上传的图像的路径
例如/storage/sdcard0/DCIM/Camera/IMG_20131214_171438.jpg
//ONCLICK LISTENER
public OnClickListener upload_image = new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(images.size() != 0) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
for(int i=0; i<images.size(); i++){
doFileUpload(images.get(i));
}
}
}
};
//上传
private void doFileUpload(String upload_file){
Log.d("Currently queued", upload_file);
HttpURLConnection conn = null;
DataOutputStream dos = null;
DataInputStream inStream = null;
String exsistingFileName = upload_file;
// Is this the place are you doing something wrong.
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "acebdf13572468";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1*1024*1024;
String urlString = "http://test.xponlm.com/MobileServices/api/ShipmentImages";
try
{
Log.e("MediaPlayer","Inside second Method");
FileInputStream fileInputStream = new FileInputStream(new File(exsistingFileName) );
URL url = new URL(urlString);
conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true);
// Allow Outputs
conn.setDoOutput(true);
// Don't use a cached copy.
conn.setUseCaches(false);
// Use a post method.
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);
dos = new DataOutputStream( conn.getOutputStream() );
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + exsistingFileName +"\"" + lineEnd);
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"ID\""+ lineEnd);
dos.writeBytes(lineEnd);
dos.writeBytes(strshipmentID + lineEnd);
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"ImageType\""+ lineEnd);
dos.writeBytes(lineEnd);
dos.writeBytes("JPG" + lineEnd);
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"FileType\""+ lineEnd);
dos.writeBytes(lineEnd);
dos.writeBytes(strtype + lineEnd);
Log.e("MediaPlayer","Headers are written");
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
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);
}
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
// tv.append(inputLine);
Log.d("inputLine", inputLine);
// close streams
Log.e("MediaPlayer","File is written");
fileInputStream.close();
dos.flush();
dos.close();
}
catch (MalformedURLException ex)
{
Log.e("MediaPlayer", "error1: " + ex.getMessage(), ex);
}
catch (IOException ioe)
{
Log.e("MediaPlayer", "error2: " + ioe.getMessage(), ioe);
}
//------------------ read the SERVER RESPONSE
try {
inStream = new DataInputStream ( conn.getInputStream() );
String str;
while (( str = inStream.readLine()) != null) {
Log.e("MediaPlayer","Server Response"+str);
}
/*while((str = inStream.readLine()) !=null ){
}*/
inStream.close();
}
catch (IOException ioex){
Log.e("MediaPlayer", "error3: " + ioex.getMessage(), ioex);
}
}
我错过了什么吗？你能说出我的代码有什么问题吗？
最佳答案
public Fileupload(String url, String userid,
String filepath, String status) {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
MultipartEntity entity = new MultipartEntity(
HttpMultipartMode.BROWSER_COMPATIBLE);
HttpParams httpParams = httpclient.getParams();
httpParams.setIntParameter(CoreConnectionPNames.SO_TIMEOUT, 100000);
try {
entity.addPart("key 1",
new StringBody(userid, Charset.forName("UTF-8")));
entity.addPart("key 2",
new StringBody(status, Charset.forName("UTF-8")));
entity.addPart("File ", new FileBody(new File(filepath)));
httppost.setEntity(entity);
ResponseHandler<String> responseHandler = new BasicResponseHandler();
String response = httpclient.execute(httppost, responseHandler);
} catch (Exception e) {
}
}
