是否可以在Retrofit2中发送包含多部分的@Fields?

我正在使用Retrofit2,我使用@FormUrlEncoded通过它发送数据,因为所有内容甚至都是字符串,甚至是图像,但是当我将图像集合作为字符串发送时遇到了一些错误,所以我更改为多部分。

现在,我面临无法发送包含多部分字符串的@Field的问题。

那么,如何在不为每个字符串使用RequestBody的情况下解决此问题?

这是我的代码

@Multipart
@POST("/androidfiles/insertNews.php")
Call<ResponseBody> uploadImage(@Part MultipartBody.Part file, @Part("name") RequestBody name,
                               @Field("tArabic") String arabicTitle,
                               @Field("tEnglish") String englishTitle,
                               @Field("tRussian") String russianTitle,
                               @Field("tItalian") String italianTitle,
                               @Field("dArabic") String arabicDescription,
                               @Field("dEnglish") String englishDescription,
                               @Field("dRussian") String russianDescription,
                               @Field("dItalian") String italianDescription);

和这里。

private void insertNews(Uri uri){

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(ServiceConstants.URL)
            .build();


    File file = FileUtil.getFile(this, uri);

    RequestBody mFile = RequestBody.create(MediaType.parse("image/*"), file);
    MultipartBody.Part fileToUpload = MultipartBody.Part.createFormData("file", file.getName(), mFile);
    RequestBody filename = RequestBody.create(MediaType.parse("text/plain"), file.getName());

    ApiConfig apiConfig = retrofit.create(ApiConfig.class);

    Call<ResponseBody> addNews = apiConfig.uploadImage(fileToUpload,
            filename,
            etArabicTitle.getText().toString(),
            etEnglishTitle.getText().toString(),
            etRussianTitle.getText().toString(),
            etItalianTitle.getText().toString(),
            etArabicDescription.getText().toString(),
            etEnglishDescription.getText().toString(),
            etRussianDescription.getText().toString(),
            etItalianDescription.getText().toString());

    addNews.enqueue(new Callback<ResponseBody>() {
        @Override
        public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
            Toast.makeText(News.this, "success" + "\n" + response.message(), Toast.LENGTH_SHORT).show();
            Intent intent = new Intent(News.this,Menu.class);
            startActivity(intent);
        }

        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) {
            Toast.makeText(News.this, "fail" + t.getMessage(), Toast.LENGTH_SHORT).show();
            t.printStackTrace();
        }
    });

}

尝试将@Field更改为@Part。像这样:

    @Multipart
@POST("/androidfiles/insertNews.php")
Call<ResponseBody> uploadImage(@Part MultipartBody.Part file, @Part("name") RequestBody name,
                               @Part("tArabic") String arabicTitle,
                               @Part("tEnglish") String englishTitle,
                               @Part("tRussian") String russianTitle,
                               @Part("tItalian") String italianTitle,
                               @Part("dArabic") String arabicDescription,
                               @Part("dEnglish") String englishDescription,
                               @Part("dRussian") String russianDescription,
                               @Part("dItalian") String italianDescription);

在使用Retrofit的多部分请求时,可以使用带有@Part字段的RequestBody批注来传递其他参数。

因此,您可以将其作为RequestBody类型的参数传递给除多部分主体之外的所有参数,如下所示:

@Multipart
@POST("/androidfiles/insertNews.php")
Call<ResponseBody> uploadImage(@Part MultipartBody.Part file,
                               @Part("name") RequestBody name,
                               @Part("tArabic") RequestBody arabicTitle,
                               @Part("tEnglish") RequestBody englishTitle,
                               @Part("tRussian") RequestBody russianTitle,
                               @Part("tItalian") RequestBody italianTitle,
                               @Part("dArabic") RequestBody arabicDescription,
                               @Part("dEnglish") RequestBody englishDescription,
                               @Part("dRussian") RequestBody russianDescription,
                               @Part("dItalian") RequestBody italianDescription);

现在,用于调用此类 API ;您需要通过使用语法RequestBody

为{strong> MIME类型 text/plain为附加参数创建(i.e. RequestBody.create(MediaType.parse("text/plain"), your variable goes here))来传递它

在建立API期间,您可以通过以下方式调用它:

Call<ResponseBody> addNews = apiConfig.uploadImage(fileToUpload,
            filename,
            RequestBody.create(MediaType.parse("text/plain"), etArabicTitle.getText().toString()), //This will make it as RequestBody to pass it along image/files.
            RequestBody.create(MediaType.parse("text/plain"), etEnglishTitle.getText().toString()),
            RequestBody.create(MediaType.parse("text/plain"), etRussianTitle.getText().toString()),
            RequestBody.create(MediaType.parse("text/plain"), etItalianTitle.getText().toString()),
            RequestBody.create(MediaType.parse("text/plain"), etArabicDescription.getText().toString()),
            RequestBody.create(MediaType.parse("text/plain"), etEnglishDescription.getText().toString()),
            RequestBody.create(MediaType.parse("text/plain"), etRussianDescription.getText().toString()),
            RequestBody.create(MediaType.parse("text/plain"), etItalianDescription.getText().toString()));
