解决Retrofit2上传中文乱码问题

• 和服务器统一编码，基本上都是UTF-8
• 给OKHTTP添加一个Interceptor（拦截器）

• .addInterceptor(new Interceptor() {
  @Override
  public Response intercept(Chain chain) throws IOException {
  Request request = chain.request();
  Request.Builder requestBuilder = request.newBuilder();
  request = requestBuilder.post(RequestBody.create(MediaType.parse("application/x-www-form-urlencoded;charset=UTF-8"),
  URLDecoder.decode(bodyToString(request.body()), "UTF-8")))
  .build();
  return chain.proceed(request);
  }
  })
