Question

我正在尝试通过php将图片从Android设备上传到服务器，但我遇到了一些问题。当文件上传时，文件似乎到达服务器（我可以看到几百kb的tmp文件），但文件没有像我想要的那样以.jpg文件的形式保存到目录中。我得到的服务器响应是500 - 内部错误。

我在服务器上放了一个基本的html表单，以便我可以从浏览器测试php上传文件，并且使用我的电脑和手机上的浏览器上传了一张图片。所以这只是我的应用程序无法正常工作。这是服务器/ php配置的问题还是它上传的方式？这是代码：

HttpURLConnection connection = null;
DataOutputStream outputStream = null;
String pathToOurFile = listOfFiles.getFirst().toString();
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary =  "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1*1024*1024;

try {
                FileInputStream fileInputStream = new FileInputStream(new File(pathToOurFile) );

                URL url = new URL(serverAddress);
                connection = (HttpURLConnection) url.openConnection();

                // Allow Inputs & Outputs
                connection.setDoInput(true);
                connection.setDoOutput(true);
                connection.setUseCaches(false);

                // Enable POST method
                connection.setRequestMethod("POST");
                connection.setRequestProperty("Connection", "Keep-Alive");
                connection.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);

                outputStream = new DataOutputStream( connection.getOutputStream() );
                outputStream.writeBytes(twoHyphens + boundary + lineEnd);
                outputStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + pathToOurFile +"\"" + lineEnd);
                outputStream.writeBytes(lineEnd);

                bytesAvailable = fileInputStream.available();
                bufferSize = Math.min(bytesAvailable, maxBufferSize);
                buffer = new byte[bufferSize];

                // Read file
                bytesRead = fileInputStream.read(buffer, 0, bufferSize);
                while (bytesRead > 0) {
                    outputStream.write(buffer, 0, bufferSize);
                    bytesAvailable = fileInputStream.available();
                    bufferSize = Math.min(bytesAvailable, maxBufferSize);
                    bytesRead = fileInputStream.read(buffer, 0, bufferSize);
                }

                outputStream.writeBytes(lineEnd);
                outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

                // Responses from the server (code and message)
                int serverResponseCode = connection.getResponseCode();
                Log.v("UPLOAD*********", "Server Code: " + serverResponseCode);
                if (serverResponseCode == 200) {
                    successfulUploads++;
                    listOfFiles.removeFirst();
                } else {
                    numberOfTries++;
                }

                fileInputStream.close();
                outputStream.flush();
                outputStream.close();
            } catch (Exception ex) {
                numberOfTries++;
            }

这是php文件：

<?php 
 $target = "uploads/"; 
 $target = $target . basename( $_FILES['uploaded']['name']) ; 

 if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target)) 
 {
 echo "The file ". basename( $_FILES['uploaded']['name']). " has been uploaded";
 } 
 else {
 echo "Sorry, there was a problem uploading your file.";
 }
 ?>

使用PHP内部错误从Android上传文件
