我要用Ion将文件上传到REST API，就像Koush提供的示例代码一样。
上传过程似乎正确完成了，这意味着我可以从uploadProgressHandler中获取上传百分比，根据这些信息我的进度条会到达末尾。但是当我到达进度条的末尾时，它并不意味着文件已经上传成功！但是出现了错误。
几次后（具体取决于文件大小，40秒到2、3分钟不等），我从API那里得到了表示视频已上传的响应！API JsonObject 响应：
if (Upload != null && !Upload.isDone() && !Upload.isCancelled()){
resetUploadReq();
return;
}
String UploadUrl = Constants.Video_Upload_URL+userToken;
Upload = Ion.with(UploadActivity.this).load(UploadUrl)
.uploadProgressHandler(new ProgressCallback() {
@Override
public void onProgress(long uploaded, long total) {
int mProgress = (int) (100*uploaded / total);
mUploadBtn.setProgress(mProgress);
}
})
.setTimeout( 15 * 1000)
.setMultipartFile("file", new File(Path))
.asJsonObject()
.setCallback(new FutureCallback<JsonObject>() {
@Override
public void onCompleted(Exception ex, JsonObject result) {
resetUploadReq();
if (ex == null){
JsonObject ReturnJson = result.getAsJsonObject();
Status = ReturnJson.get("status").getAsBoolean();
if (Status == true){
VIDEO = ReturnJson.get("video").getAsString();
// ConvertingCheck(VIDEO);
}else{
mUploadBtn.setProgress(0);
Crouton.makeText(UploadActivity.this, "An Error occurred, Try again later", Style.ALERT).show();
}
}else{
mUploadBtn.setProgress(0);
Crouton.makeText(UploadActivity.this, "An Error occurred, Try again later", Style.ALERT).show();
ex.printStackTrace();
return;
}
}
});
