java - Retrofit2上传图片失败

问题描述

上传的时候报错： onFailure=Use JsonReader.setLenient(true) to accept malformed JSON at line 15 column 1 path $多次修改URL地址和模型都是这个错误

这是Retrofit接口代码···public interface ImageUpload {

//上传图片@Multipart@POST('/xxzx/a/tpsb/uploadPicture')Call<UploadResult> uploadMultipleFiles(@PartMap Map<String, RequestBody> files);

}···

Retrofit 调用代码···public class ServiceGenerator {

private static final String API_BASE_URL= 'http://114.115.139.232:8080/';private static OkHttpClient.Builder httpClient = new OkHttpClient.Builder();private static Retrofit.Builder builder =new Retrofit.Builder().baseUrl(API_BASE_URL).addConverterFactory(GsonConverterFactory.create());public static <S> S createService(Class<S> serviceClass){ Retrofit retrofit = builder.client(httpClient.build()).build(); return retrofit.create(serviceClass);}

}···

以下是调用方法：··· private void uploadFiles() {

if(imagesList.size()==0){Toast.makeText(MainActivity.this, '没有选择图片', Toast.LENGTH_SHORT).show();return; } Map<String, RequestBody>files = new HashMap<>(); //ImageUpload是interface不是class，所以我们是无法直接调用该方法，需要用Retrofit创建一个ImageUpload的代理对象 final ImageUpload service = ServiceGenerator.createService(ImageUpload.class); for (int i = 0;i<imagesList.size();i++){File file = new File(imagesList.get(i).path);files.put('file' + i + ''; filename='' + file.getName(),RequestBody.create(MediaType.parse(imagesList.get(i).mimeType), file)); } Call<UploadResult> call = service.uploadMultipleFiles(files); call.enqueue(new Callback<UploadResult>() {@Overridepublic void onResponse(Call<UploadResult> call, Response<UploadResult> response) { if (response.isSuccessful()){Toast.makeText(MainActivity.this, '上传成功', Toast.LENGTH_SHORT).show();Log.i('图片上传：','---------------------上传成功-----------------------'); }}@Overridepublic void onFailure(Call<UploadResult>call, Throwable t) { Log.i('wxl', 'onFailure=' + t.getMessage()); Toast.makeText(MainActivity.this,'上传失败', Toast.LENGTH_SHORT).show();} });}

···

这是使用Postman post成功的返回json：{ 'failureList': [], 'successNum': 1, 'failureNum': 0}

这是报错的内容：05-06 16:15:43.599 19961-19961/com.example.yuan.imagerecognitionmanager I/wxl: onFailure=Use JsonReader.setLenient(true) to accept malformed JSON at line 15 column 1 path $

javabean：public class UploadResult<T> {

public int successNum;public int failureNum;public ArrayList<String> failureList;

}

问题解答

http://stackoverflow.com/ques... 可以参考下这里。

主要是这个

Gson gson = new GsonBuilder().setLenient().create();Retrofit retrofit = new Retrofit.Builder().baseUrl(BASE_URL).client(client).addConverterFactory(GsonConverterFactory.create(gson)).build();
