在我的最新应用中,我将使用Koush Ion库。这个库很方便,但是我在上传文件到我的REST服务器时遇到了问题。 注意:我的服务器响应成功上传的过程是1。
我的代码如下:
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
}
})
;
}
});
但是我从服务器得到了TimeoutException错误。 我的问题是: 1.我的文件选择方式是否正确?! 2.我应该使用Future Callback作为字符串吗?!
我通过Fiddler2检查了对服务器的请求,当我尝试上传文件到服务器时...它向我显示请求已发送,multipartParameters已发送,但是当尝试发送文件时... Fiddler向我显示错误:
Protocol Violation Report:
Content-Length mismatch: Request Header indicated 455 bytes, but client sent 387 bytes.
