上傳文件到服務器使用參數

我想上傳文件到額外的PARAMS服務器，但沒有成功：上傳文件到服務器使用參數

從Web控制檯表單數據：

Request URL: ../upload-photo 
Request Method:POST 
Status Code:403 Forbidden 
Request Headersview source 
Accept:application/json, text/javascript, */*; q=0.01 
Accept-Encoding:gzip,deflate,sdch 
Connection:keep-alive 
Content-Length:753249 
Content-Type:multipart/form-data; boundary=----WebKitFormBoundaryKWTNLV05FNLs29bB 
X-Requested-With:XMLHttpRequest 
Request Payload 
------WebKitFormBoundaryKWTNLV05FNLs29bB 
Content-Disposition: form-data; name="latitude" 

1212.22 
------WebKitFormBoundaryKWTNLV05FNLs29bB 
Content-Disposition: form-data; name="longitude" 

1212.22 
------WebKitFormBoundaryKWTNLV05FNLs29bB 
Content-Disposition: form-data; name="start_record" 

212 
------WebKitFormBoundaryKWTNLV05FNLs29bB 
Content-Disposition: form-data; name="file"; filename="IMAG2286.jpg" 
Content-Type: image/jpeg

我的代碼：

public static void uploadFile(String filePath) { 

     FileInputStream fileInputStream = null; 
     HttpURLConnection connection = null; 
     DataOutputStream dataOutputStream = null; 
     int bytesRead, bytesAvailable, bufferSize; 
     byte[] buffer; 
     int maxBufferSize = 1 * 1024 * 1024; 
     File sourceFile = new File(filePath); 

     if (!sourceFile.isFile()) { 
      Log.e("uploadFile", "Source File not exist "); 
     } else { 

      try { 

       fileInputStream = new FileInputStream(sourceFile); 
       URL url = new URL(SERVER_URI); 
       connection = (HttpURLConnection) url.openConnection(); 

       connection.setDoInput(true); 
       connection.setDoOutput(true); 
       connection.setUseCaches(false); 
       connection.setRequestMethod("POST"); 
       connection.setRequestProperty("Connection", "Keep-Alive"); 
       connection.setRequestProperty("Content-Type", 
         "multipart/form-data; boundary=----WebKitFormBoundaryKWTNLV05FNLs29bB"); 

       dataOutputStream = new DataOutputStream(
         connection.getOutputStream()); 


       dataOutputStream.writeBytes(BOUNDARY); 
       dataOutputStream.writeBytes("Content-Disposition: form-data; name=\"latitude\"\n"); 
       dataOutputStream.writeBytes("44.44"); 
       dataOutputStream.writeBytes("Content-Disposition: form-data; name=\"longitude\"\n"); 
       dataOutputStream.writeBytes("123"); 
       dataOutputStream.writeBytes("Content-Disposition: form-data; name=\"start_record\"\n"); 
       dataOutputStream.writeBytes("123"); 
       dataOutputStream.writeBytes("------WebKitFormBoundaryKWTNLV05FNLs29bB\n" + 
         "Content-Disposition: form-data; name=\"file\"; filename=\"IMAG2286.jpg\"\n" + 
         "Content-Type: image/jpeg\n"); 


       bytesAvailable = fileInputStream.available(); 
       bufferSize = Math.min(bytesAvailable, maxBufferSize); 
       buffer = new byte[bufferSize]; 
       bytesRead = fileInputStream.read(buffer, 0, bufferSize); 

       while (bytesRead > 0) { 

        dataOutputStream.write(buffer, 0, bufferSize); 
        bytesAvailable = fileInputStream.available(); 
        bufferSize = Math.min(bytesAvailable, maxBufferSize); 
        bytesRead = fileInputStream.read(buffer, 0, bufferSize); 

       } 

       dataOutputStream.writeBytes(lineEnd); 
       dataOutputStream.writeBytes(separator + boundary + separator 
         + lineEnd); 


      } catch (FileNotFoundException e) { 
       e.printStackTrace(); 
      } catch (MalformedURLException e) { 
       e.printStackTrace(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } finally { 
       try { 
        fileInputStream.close(); 
        dataOutputStream.flush(); 
        dataOutputStream.close(); 
       } catch (IOException e) { 
        e.printStackTrace(); 
       } 

      } 

     } 
    }

您可以使用準備好的MultiPartEntity來執行此操作：

HttpParams params = new BasicHttpParams(); 
params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); 
HttpClient httpClient = new DefaultHttpClient(params); 

try { 
    HttpPost httpPost = new HttpPost(Statics.BASE_URL + "/"); 

    MultipartEntity multipartEntity = new MultipartEntity(); 

    if (imagePath.length() > 0) { 
     multipartEntity.addPart("images", new FileBody(new File(imagePath))); 
    } 

    httpPost.setEntity(multipartEntity); 

    String resp = httpClient.execute(httpPost, new BasicResponseHandler()); 

} catch (Exception e) { 
}

你可以使用async-http-client庫。

它太容易使用
