使用改進發送帶有參數的多部分（文件）

我想將文件（Image）和一些參數發送到服務器，然後我的php腳本將它們發送到數據庫。我已經嘗試過了。我的文件已上傳到服務器，文件的名稱已上載到數據庫中，但不包含參數。使用改進發送帶有參數的多部分（文件）

我將顯示我的代碼。我希望你能幫助我。

ApiService.java

public interface ApiService { 

    /* 
    Retrofit get annotation with our URL 
    And our method that will return us the List of Contacts 
    */

    @POST("upload(Testing).php") 
    Call<Result> uploadImage(@Part MultipartBody.Part file, 
          @Part("id_user") RequestBody idUser, 
          @Part("p_id_doc_proj") RequestBody p_id_doc_proj,

UPDATE

這是我的服務器端代碼

<?php 
    $file_path = ""; 
    $id_project = $_REQUEST["id_project"]; 
    $p_id_doc_proj = $_REQUEST["p_id_doc_proj"]; 
    $id_doc_type = $_REQUEST["id_doc_type"]; 
    $id_user = $_REQUEST["id_user"]; 

    $url1 = "http://172.x.x.x/Upload_Ruben/"; 
    $url2 = $file_path.basename($_FILES['uploaded_file']['name']); 
    $url = $url1.$url2; 

    if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $url2)){ 
     $ws = "http://172.x.x.x:xxxx/UploadImage/$id_project/$p_id_doc_proj/$id_doc_type/$id_user/$url"; 

     $opts = array('http'=>array('header'=>'Content-type: application/x-www-form-urlencoded')); 

     $context = stream_context_create($opts); 

     $arrayLog = array(); 
     $data1 = file_get_contents($ws, false, $context); 
     $result = json_encode($data1); 
    }else{ 
     $result = array("result" => "error"); 
    } 
?>

這裏是你如何把它

@Multipart 
@POST("/edit_user_profile") 
Call<String> editProfileServerCall(@Part("access_token") RequestBody 
accessToken, @Part("user_name") RequestBody name, @Part("user_mobile") 
RequestBody userPhone, @Part("user_email") RequestBody email, @Part 
MultipartBody.Part image);

這裏是你怎麼稱呼它 -

public void editProfileServerCall(final Context context, String name, String phoneNumber, File image, String email, final ProfilePresenter.EditProfilePresenter editProfilePresenter) { 

    editProfilePresenter.showLoader(); 
    RequestBody userName = RequestBody.create(MediaType.parse("text/plain"), name); 
    RequestBody userPhone = RequestBody.create(MediaType.parse("text/plain"), phoneNumber); 
    RequestBody userEmail = RequestBody.create(MediaType.parse("text/plain"), email); 
    RequestBody accessToken = RequestBody.create(MediaType.parse("text/plain"), Constants.userData.getAccessToken()); 
    RequestBody file = RequestBody.create(MediaType.parse("image/jpg"), image); 
    MultipartBody.Part userImage = MultipartBody.Part.createFormData("user_image", image.getName(), file); 
    RestClient.getApiService().editProfileServerCall(accessToken, userName, userPhone, userEmail, userImage).enqueue(new Callback<String>() { 
     @Override 
     public void onResponse(Call<String> call, Response<String> response) { 
      editProfilePresenter.hideLoader(); 
      Log.e("edit_profile_response",""+ response.body().toString()); 
      try { 
       JSONObject object = new JSONObject(response.body().toString()); 
       if (object.getInt("is_error") == 0) { 
        if (object.has("user_profile")) { 
         CommonParser.parseProfileData(context, object.getJSONObject("user_profile")); 
         editProfilePresenter.success(); 
        } 
       } else { 
        editProfilePresenter.error(Constants.popupResponseObject.getJSONObject("" + object.getInt("flag")).getString("text")); 
       } 
      } catch (JSONException e) { 
       e.printStackTrace(); 
       editProfilePresenter.error(Constants.serverError); 
      } 
     } 

     @Override 
     public void onFailure(Call<String> call, Throwable t) { 
      editProfilePresenter.hideLoader(); 
      editProfilePresenter.error(Constants.serverError); 
     } 
    }); 

}

我已經試過你的代碼，但答覆總是onfailure –

然後我的朋友問題是在服務器端.. –

是的，我想我沒有得到所有的參數，只有圖像的網址。我更新了我的問題。你可以幫幫我嗎？我是新創建PHP服務器端腳本。 –

使用改進發送帶有參數的多部分（文件）
