java - 使用改造发送带有一些参数的多部分(文件)

Question

我想将文件(图片)和一些参数发送到服务器，然后我的 php 脚本将它们发送到数据库。我已经试过了。我的文件已上传到服务器，文件名已上传到数据库，但没有包含参数。

我会展示我的代码。我希望你能帮助我。

APIService.java

public interface ApiService {

    /*
    Retrofit get annotation with our URL
    And our method that will return us the List of Contacts
    */
    @Multipart
    @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,
                             @Part("id_doc_type") RequestBody id_doc_type,
                             @Part("id_project") RequestBody idProject);

这是我的服务器端代码

<?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();

发送方式如下

@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);

这里是你如何调用它 -

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);
        }
    });

}
