在我的上一个应用程序中我将使用库什离子图书馆。它非常方便，但我在将文件上传到我的休息服务器时遇到问题。 注意：我的服务器对成功上传过程的响应是1
我的代码我喜欢这样：
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
}
})
;
}
});
但我从服务器收到 TimeoutException。我的问题是： 1.我所做的选择文件的方法正确吗？ 2. 应该使用 Future Callback 作为 String 吗？！
我通过 fiddler2 检查对服务器的请求，当我尝试将文件上传到服务器时...它显示请求发送，已发送多部分参数，但是当尝试发送文件时...fiddler 显示错误：
Protocol Violation Report:
Content-Length mismatch: Request Header indicated 455 bytes, but client sent 387 bytes.
我实际上为我工作，这是我的代码：
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();
}
});
}
希望它对某人有帮助:)
