Retrofit开发过程中遇见的bug(持续更新)

按照下面流程开发时遇到的bug

java.lang.IllegalArgumentException: @PartMap parameters can only be used with multipart encoding. (parameter #9

利用retrofit进行上传图片请求时’

ApiNet中的注解`

@POST("orders-comments")  Observable<EvaluateEntity> sendEvaluate(@HeaderMap Map<String,String> headers,@Query("productId"),@QueryMap Map<String,String> map,@PartMap() Map<String, RequestBody> file);

封装的方法

public void sendEvaluate(Subscriber<EvaluateEntity> subscriber,Map requestToken,long productId,long Map<String,String> map,Map<String, RequestBody> partParams){   mApiNet.sendEvaluate(requestToken,productId,shopId,anonymity,description,logistics,attitude,map,partParams)        .subscribeOn(Schedulers.io())        .unsubscribeOn(Schedulers.io())        .observeOn(AndroidSchedulers.mainThread())        .subscribe(subscriber);  }

请求数据时得应用

 private void sendPublish() {    String content;    Map<String, RequestBody> partParams;    List<String> list = new ArrayList<String>();    for (int i = 0; i < Bimp.drr.size(); i++) {      String Str = Bimp.drr.get(i)          .substring(Bimp.drr.get(i).lastIndexOf("/") + 1, Bimp.drr.get(i).lastIndexOf("."));      list.add(FileUtils.SDPATH + Str + ".JPEG");    }    if (list.size() > 0) {      partParams = new HashMap<>();      for (int i = 0; i < list.size(); i++) {        BufferedInputStream in = null;        try {          in = new BufferedInputStream(new FileInputStream(new File(list.get(i))));          BitmapFactory.Options options = new BitmapFactory.Options();          options.inJustDecodeBounds = true;          BitmapFactory.decodeStream(in, null, options);          partParams.put("file\";filename=\"" + i + "#" + options.outWidth + "#" + options.outHeight + ".jpeg",          RequestBody.create(MediaType.parse("multipart/form-data"), new File(list.get(i))));          System.out.println(i + "#" + options.outWidth + "#" + options.outHeight + ".jpeg");          in.close();        } catch (IOException e) {          e.printStackTrace();        }      }    } else {      Toast.makeText(getContext(), "图片为空", Toast.LENGTH_SHORT).show();      return;    }    Map<String, String> filedParams = new HashMap<>();    if (etPostDesc.getText().toString().isEmpty()) {    } else {      content = etPostDesc.getText().toString().trim();      filedParams.put("context", content);    }    unsubscribe();    //利用封装后的retrofit来请求    Subscriber mSubscriber = new Subscriber<EvaluateEntity>() {      @Override public void onCompleted() {      }      @Override public void onError(Throwable e) {        if (isNetCollect) {          stateLayout.showEmpty();        } else {          stateLayout.showError();        }      }      @Override public void onNext(EvaluateEntity EvaluateEntity) {        if (EvaluateEntity.getState() == 0) {          stateLayout.showContent();          if (rlNetStates != null) {            rlNetStates.setVisibility(View.GONE);          }          Toast.makeText(getContext(), "发布成功", Toast.LENGTH_SHORT).show();          Bimp.bmp.clear();          Bimp.drr.clear();          Bimp.max = 0;        }      }    };    HttpMethods.getInstance()        .sendEvaluate(mSubscriber, GetToken.getAccessToken(), productId, filedParams, partParams);  }

上面bug的解决办法

• 只需要在ApiNet中添加一个注解

**@Multipart**  @POST("orders-comments")  Observable<EvaluateEntity> sendEvaluate(@HeaderMap Map<String,String> headers,@Query("productId") long productId  ,@QueryMap Map<String,String> map,@PartMap() Map<String, RequestBody> file);

问题2
java.lang.IllegalStateException: Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 81

利用封装好的retrofit进行网络请求,接口和参数都没有问题,但就是请求不到数据,如果在onError中debug异常e.printStackTrace();就会看到此bug

这种bug的意思是你按对象解析的，而实际它是一个数组
其实还是因为retrofit内部json解析时出现了问题
接下来看你封装的retrofit

我先前封装的retrofit

mRetrofit = new Retrofit.Builder()        .client(httpClientBuilder.build())        .addConverterFactory(GsonConverterFactory.create())        .addCallAdapterFactory(RxJavaCallAdapterFactory.create())     .baseUrl(BASE_URL)        .build();

解决bug

修改GSON为fastjson

mRetrofit = new Retrofit.Builder()        .client(httpClientBuilder.build())        //.addConverterFactory(GsonConverterFactory.create())        .addCallAdapterFactory(RxJavaCallAdapterFactory.create())        .addConverterFactory(FastJsonConverterFactory.create())        .baseUrl(BASE_URL)        .build();
