嗨我寫了一個代碼,如下所示從我的android手機上傳文件到PHP服務器。應用程序運行時沒有任何錯誤,但文件未上傳到服務器。我哪裏做錯了 ?文件是不是從Android上傳到PHP服務器
公共類上傳延伸活動{
HttpURLConnection connection = null;
DataOutputStream outputStream = null;

String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1*1024*1024;

它運行時沒有錯誤,因爲您可以捕獲Java代碼中的所有潛在錯誤。在代碼的catch代碼塊中放入一個'Log'語句,看看它爲什麼失敗。 – Haphazard
你可以發佈PHP文件中的代碼嗎?此外,您嘗試上傳的文件的大小以及php.ini中的upload_max_filesize的值是多少? PHP腳本是否已知可以工作? – Cez
對不起,PHP代碼並不明顯,所以你可以忽略代碼 – Cez
