使用 Koush Ion 库上传多部分文件 [英] Uploading multipart file with Koush Ion library
问题描述
在我的上一个应用程序中,我将使用 Koush Ion 库.它非常方便,但我在将文件上传到我的休息服务器时遇到了问题.注意:我的服务器对成功上传过程的响应是 1
In my last app I'm going to use Koush Ion library. It's so handy but i have a problem with uploading file to my rest server. note: My server response to success upload Process is 1
我喜欢这样的代码:
public class MainActivity extends Activity {
Button upload, login;
TextView uploadCount;
ProgressBar progressBar;
String token, FilePath;
Future<String> uploading;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
upload = (Button) findViewById(R.id.upload);
uploadCount = (TextView) findViewById(R.id.upload_count);
progressBar = (ProgressBar) findViewById(R.id.progress);
token = "147c85ce29dc585966271280d59899a02b94c020";
FilePath = Environment.getExternalStorageDirectory().toString()+"/police.mp3";
upload.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (uploading !=null && !uploading.isCancelled()){
resetUpload();
return;
}
upload.setText("Uploading...");
uploading = Ion.with(MainActivity.this)
.load("http://myserver.com/api/v1/tone/upload/?token="+token)
.setLogging("UPLOAD LOGS:", Log.DEBUG)
.uploadProgressBar(progressBar)
.uploadProgressHandler(new ProgressCallback() {
@Override
public void onProgress(int downloaded, int total) {
uploadCount.setText("" + downloaded + "/" + total);
}
})
.setMultipartParameter("title", "police")
.setMultipartParameter("category", "7")
.setMultipartFile("file_url", new File(FilePath))
.asString()
.setCallback( new FutureCallback<String>() {
@Override
public void onCompleted(Exception e, String result) {
// TODO Auto-generated method stub
}
})
;
}
});
但是我从服务器收到了 TimeoutException.我的问题是:1. 选择文件的方式正确吗?!2. 应该使用 Future Callback 作为 String 吗?!
But I got TimeoutException from server. my questions are: 1. Is it right way for selecting file that I've done?! 2. Should is use Future Callback as String?!
我通过 fiddler2 检查我对服务器的请求,当我尝试将文件上传到服务器时...它向我显示请求发送,multipartParameters 发送但是当尝试发送文件时...fiddler 向我显示错误:
I check my request to server by fiddler2, when I try to upload file to server...it show me that request send, multipartParameters send but when try to send file...fiddler show me the error:
Protocol Violation Report:
Content-Length mismatch: Request Header indicated 455 bytes, but client sent 387 bytes.
推荐答案
我实际上为我工作,这是我的代码:
I actually works for me, Here is my code:
final File fileToUpload = new File(localFilePath);
Ion.with(context)
.load(Urls.UPLOAD_PICTURE)
.uploadProgressHandler(new ProgressCallback() {
@Override
public void onProgress(long uploaded, long total) {
// Displays the progress bar for the first time.
mNotifyManager.notify(notificationId, mBuilder.build());
mBuilder.setProgress((int) total, (int) uploaded, false);
}
})
.setTimeout(60 * 60 * 1000)
.setMultipartFile("upload", "image/jpeg", fileToUpload)
.asJsonObject()
// run a callback on completion
.setCallback(new FutureCallback<JsonObject>() {
@Override
public void onCompleted(Exception e, JsonObject result) {
// When the loop is finished, updates the notification
mBuilder.setContentText("Upload complete")
// Removes the progress bar
.setProgress(0, 0, false);
mNotifyManager.notify(notificationId, mBuilder.build());
if (e != null) {
Toast.makeText(context, "Error uploading file", Toast.LENGTH_LONG).show();
return;
}
Toast.makeText(context, "File upload complete", Toast.LENGTH_LONG).show();
}
});
}
