[英]multipart request on Android goes to timeout
我需要使用multipart從我的Android設備上載一個文件,並嘗試使用以下代碼,但沒有成功。 我有一個連接超時異常,並嘗試了具有相同結果的不同代碼。
try
{
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(URL);
MultipartEntityBuilder entityBuilder = MultipartEntityBuilder.create();
entityBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
entityBuilder.addTextBody(USER_ID, "DFD");
entityBuilder.addTextBody(NAME, "DFD");
String filepath = Environment.getExternalStorageDirectory() + "/Download/myImage.jpg";
Log.d(MULTIPART_TAG, filepath);
File file = new File(filepath);
if(file != null)
{
entityBuilder.addBinaryBody("IMAGE", file);
}
HttpEntity entity = entityBuilder.build();
post.setEntity(entity);
HttpResponse response = client.execute(post);
HttpEntity httpEntity = response.getEntity();
String result = EntityUtils.toString(httpEntity);
Log.v("result", result);
}
catch(Exception e)
{
e.printStackTrace();
}
這是我得到的例外:
08-06 17:49:03.006:W / System.err(24761):原因:libcore.io.ErrnoException:連接失敗:ETIMEDOUT(連接超時)
我還嘗試了以下解決方案:
https://stackoverflow.com/a/19188010/1948785
以及已棄用的類MultipartEntity
我的第二個問題是此警告的含義是什么(我不知道它是否與我的問題有關,但是在執行請求時會得到它):
08-06 17:45:53.461:W / dalvikvm(24761):VFY:無法解析Lorg / apache / http / message / BasicHeaderValueParser中的靜態字段3008(INSTANCE);
我正在使用的庫是:
嘗試這個 ,
DefaultHttpClient httpClient = new DefaultHttpClient();
// yourimagefile is your imagefile
HttpPost httpPostRequest = new HttpPost(URL);
// Try This
httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
MultipartEntity mpEntity = new MultipartEntity();
ContentBody cbFile = new FileBody(yourimagefile, "image/jpeg");
mpEntity.addPart("file", cbFile);
httpPostRequest.setEntity(mpEntity);
HttpResponse response = (HttpResponse) httpclient.execute(httpPostRequest);
嘗試設置HttpClient的超時時間。
int TIMEOUT_MILLISEC = 20000; // = 20 seconds
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams, TIMEOUT_MILLISEC);
HttpConnectionParams.setSoTimeout(httpParams, TIMEOUT_MILLISEC);
HttpClient client = new DefaultHttpClient(httpParams);
檢查圖像的尺寸。 可能是圖像太大,並且上載時間很長,並且服務器在該連接上發出了超時。
