我试图将图像文件从SD卡上传到php服务器。所以在上传时我得到了内部服务器错误500.我在服务器中也创建了uploads文件夹。但图像不会上传到特定文件夹。

我的代码:

 TextView messageText;
    Button uploadButton;
    int serverResponseCode = 0;
    ProgressDialog dialog = null;

    String upLoadServerUri = null;

    /**********  File Path *************/
    final String uploadFilePath = "/storage/sdcard0/";
    final String uploadFileName = "temp.jpg";

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        uploadButton = (Button)findViewById(R.id.uploadButton);
        messageText  = (TextView)findViewById(R.id.messageText);

        messageText.setText("Uploading file path :- '/mnt/sdcard/"+uploadFileName+"'");

        /************* Php script path ****************/
        upLoadServerUri = "http://example.com/android/uploadserver.php";

        uploadButton.setOnClickListener(new OnClickListener() {            
            @Override
            public void onClick(View v) {

                dialog = ProgressDialog.show(MainActivity.this, "", "Uploading file...", true);

                new Thread(new Runnable() {

                                    }
                                });                      

                             uploadFile(uploadFilePath + "" + uploadFileName);

                        }

              return serverResponseCode; 

           } // End else block 
         } 
        }

Php编码是:

       < ?php
   $file_path = "uploads/";
   $file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
   if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
       echo "success";
   } 
   else{
       echo "fail";
   }
   ? >

错误500(内部服务器错误)问题导致服务器端没有   客户端。请尝试获取500的响应代码。   最终它应该在服务器端而不是客户端处理。所以,请   首先测试您的Web服务

我的PHP代码是,

<?php
$target_path1 = "uploads/";
$randno=mt_rand(1,15000);
/* Add the original filename to our target path.
Result is "uploads/filename.extension" */
$target_path1 = $target_path1 . basename($randno.$_FILES['uploaded_file']['name']);


if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $target_path1)) {
    echo "The first file ".  basename($randno. $_FILES['uploaded_file']['name']).
    " has been uploaded.";
} else{
    echo "There was an error uploading the file, please try again!";
    echo "filename: " .  basename( $_FILES['uploaded_file']['name']);
    echo "target_path: " .$target_path1;
}
?>

非常感谢!!!
