Retrofit 打印log时，中文会显示类似%E8%BE%BD字符

参照Android Retrofit2.1.0设置编码格式GBK 的文章。

OkHttpClient.Builder builder = new OkHttpClient().newBuilder();
        /***lyl TODO 下面一行代码加入https的接口访问**/
        //builder.sslSocketFactory(getSSLSocketFactory(context));
        builder.addInterceptor(new Interceptor() {
            @Override
            public Response intercept(Interceptor.Chain chain) throws IOException {
                Request original = chain.request();
            // Request customization: add request headers
//            Log.d(TAG, fdata);StringUtil.encryptAsDoNet(fdata, 1)
//            Log.d(TAG, "加密后："+DESUtils.encryptAsDoNet(fdata, 1));
                Request.Builder requestBuilder = null;
                try {
                    requestBuilder = original.newBuilder()
                            .addHeader("androidorios", "android");
                } catch (Exception e) {
                    LogUtil.e(TAG,"---create--addhead---"+e.toString());
                }
                Request request = requestBuilder.build();
                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);
        }
        });

就可以解决问题。

今日我们产品在测试时，发现有个接口提示请求失败。我log显示：

---onError--Throwable-java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String okhttp3.MediaType.toString()' on a null object reference

首先想到除了这次改动，其他没涉及到。查看了自己这个接口恰恰：传递的参数是空的。所以更能判断是自己这里少加了非空的判断。修改后的代码如下：

Request request = requestBuilder.build();
                if(null!=request&&request.body().contentLength()>0) {
                    LogUtil.d(UrlConfig.OkHttp, "---request.body.type--" + request.body().contentType().toString());
                    if ((request.body().contentType().toString()).equals("application/x-www-form-urlencoded")) {
                        request = requestBuilder.post(RequestBody.create(MediaType.parse("application/x-www-form-urlencoded;charset=utf-8"),
                                URLDecoder.decode(bodyToString(request.body()), "UTF-8")))
                                .build();
                    }
                }
