如何使用retrofit在android中上传多张图片

implementation 'com.squareup.retrofit2:retrofit:2.x.x'
implementation 'com.squareup.retrofit2:converter-gson:2.x.x' // 如果需要使用Gson解析返回的数据
implementation 'com.squareup.okhttp3:logging-interceptor:4.x.x' // 如果需要查看网络请求日志

public interface UploadService {
    @Multipart
    @POST("upload")
    Call<ResponseBody> uploadImages(
        @Part List<MultipartBody.Part> images
    );
}

OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
httpClient.addInterceptor(new HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BODY));

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl("http://your-api-url.com/") // 替换为实际的API地址
    .addConverterFactory(GsonConverterFactory.create()) // 如果需要使用Gson解析返回的数据
    .client(httpClient.build())
    .build();

UploadService uploadService = retrofit.create(UploadService.class);

List<MultipartBody.Part> images = new ArrayList<>();
for (String imagePath : imagePaths) {
    File file = new File(imagePath);
    RequestBody requestBody = RequestBody.create(MediaType.parse("image/*"), file);
    MultipartBody.Part imagePart = MultipartBody.Part.createFormData("image", file.getName(), requestBody);
    images.add(imagePart);
}

Call<ResponseBody> call = uploadService.uploadImages(images);
call.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
        // 处理上传成功的响应
    }

    @Override
    public void onFailure(Call<ResponseBody> call, Throwable t) {
        // 处理上传失败的情况
    }
});
