Loopj库不能与Codeigniter文件上传

Question

我试图从我的Android应用程序与Loopj库上传图像到服务器。在服务器端，我使用Codeigniter和文件上传库。但Codeigniter总是给我这个错误，即使我尝试了允许的扩展。

The file type you are attempting to upload is not allowed 

这是我的图片上传代码

public void post_image() throws JSONException 

{ 
    RequestParams params = new RequestParams(); 
    params.put("id_objek", id_objek); 
    params.put("id_user",id_user); 
    File myFile = new File(url_gambar); 
    try { 
     params.put("user_file", myFile); 
    } catch(FileNotFoundException e) {} 

    ApiRequest.post(url_gambar, params, new JsonHttpResponseHandler() { 
     @Override 
     public void onSuccess(int statusCode, Header[] headers, JSONObject response) { 
      // If the response is JSONObject instead of expected JSONArray 
     } 

     @Override 
     public void onSuccess(int statusCode, Header[] headers, JSONArray res) { 

      try { 
       JSONObject obj = res.getJSONObject(0); 
       String status = obj.getString("status"); 
       String message = obj.getString("message"); 

       if(status=="1"){ 
        Toast.makeText(getApplication(),"Sukses:"+message,Toast.LENGTH_SHORT).show(); 
       }else{ 
        Toast.makeText(getApplication(),"Terjadi kesalahan:"+message,Toast.LENGTH_SHORT).show(); 
       } 

      } catch (JSONException e) { 
       e.printStackTrace(); 
      } 

     } 
    }); 
} 

这是在服务器端我的文件上传代码

if (empty($_FILES['user_file']['name'])) { 
      echo '['.json_encode(array(
       'status'=>"0", 
       'message'=>'Gambar kosong' 
      )).']'; 
    }else{ 

      $info=null; 
      $config['upload_path'] = './images/gallery'; 
      $config['allowed_types'] = 'gif|jpg|jpeg|png|jpeg|bmp'; 
      $config['max_size'] = '5000'; 
      $config['max_width'] = '5000'; 
      $config['max_height'] = '2000'; 
      $config['remove_spaces'] = 'true'; 

      $this->load->library('upload'); 
      $this->upload->initialize($config); 

      if (!$this->upload->do_upload('user_file')) { 
       echo '['.json_encode(array(
        'status'=>"0", 
        'message'=>$this->upload->display_errors().'-'.$_FILES['user_file']['name'] 
       )).']'; 

      } else { 

       $info = $this->upload->data();     
       $thumb_config['image_library'] = 'gd2'; 
       $thumb_config['source_image'] = $info['full_path']; 
       $thumb_config['create_thumb'] = TRUE; 
       $thumb_config['maintain_ratio'] = TRUE; 
       $thumb_config['width'] = 600; 
       $thumb_config['height'] = 600; 
       $this->load->library('image_lib'); 
       $this->image_lib->initialize($thumb_config); 
       $this->image_lib->resize(); 

       if ($nama_gambar == null) 
        $nama_gambar = $info['file_name']; 

       echo '['.json_encode(array(
        'status'=>"1", 
        'message'=>$nama_gambar 
       )).']'; 
      } 
    } 

任何帮助或建议将不胜感激！

现在我的代码工作后，我改变文件上传代码在服务器端。我重写我的上传代码没有Codeigniter文件上传库。我一直在寻找这个问题，但找不到任何答案。这是我在服务器端的代码

... 
    $target_dir = "./images/gallery/"; 
    $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]); 
    $uploadOk = 1; 
    $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION); 
    $message = ""; 
    // Check if image file is a actual image or fake image 
    if(isset($_POST["submit"])) { 
     $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]); 
     if($check !== false) { 
      echo "File is an image - " . $check["mime"] . "."; 
      $uploadOk = 1; 
     } else { 
      echo "File is not an image."; 
      $uploadOk = 0; 
     } 
    } 
    // Check if file already exists 
    /* 
    if (file_exists($target_file)) { 
     $message = "Sorry, file already exists."; 
     $uploadOk = 0; 
    } 
    */ 
    // Check file size 
    if ($_FILES["fileToUpload"]["size"] > 500000) { 
     $message = "Gambar terlalu besar"; 
     $uploadOk = 0; 
    } 
    // Allow certain file formats 
    if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg" 
    && $imageFileType != "gif") { 
     $message = "Format gambar hanya bole JPG, PNG dan GIF"; 
     $uploadOk = 0; 
    } 
    // Check if $uploadOk is set to 0 by an error 
    if ($uploadOk == 0) { 
     $message = "Terjadi kesalahan saat upload gambar"; 
    // if everything is ok, try to upload file 
    } else { 
     if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) { 
      echo '['.json_encode(array(
       'status'=>"1", 
       'message'=>"Upload gambar sukses" 
      )).']'; 
     } else { 
      echo '['.json_encode(array(
       'status'=>"0", 
       'message'=>$message 
      )).']'; 
     } 
    }
