Android retrofit2 添加Header body加密，返回参数分析

1、添加Header

OkHttpClient.Builder httpClient = new OkHttpClient.Builder();

//添加Log
httpClient.addNetworkInterceptor(getInterceptor(true));

//添加固定的header参数
httpClient.readTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS);
httpClient.connectTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS);
httpClient.writeTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS);

?

//针对不同的情况写 Log  <br>private HttpLoggingInterceptor getInterceptor(boolean debug) {     HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();     if (debug) {         interceptor.setLevel(HttpLoggingInterceptor.Level.BODY); // 测试     } else {         interceptor.setLevel(HttpLoggingInterceptor.Level.NONE); // 打包     }     return interceptor; }

　　

//添加动态的Header
httpClient.addInterceptor(new HttpHeadInterceptor());

private class HttpHeadInterceptor implements Interceptor {
public HttpHeadInterceptor() {
       
    }

    @Override
    public okhttp3.Response intercept(Chain chain) throws IOException {
        Request originalRequest = chain.request();
        Request.Builder requestBuilder = originalRequest.newBuilder();


        requestBuilder.addHeader("time", "时间");

        //添加User-Agent
        String user = HttpHead.getUserAgent();
        requestBuilder.addHeader("User-Agent", user);


        Request request = requestBuilder.build();
        okhttp3.Response response = chain.proceed(request);

        //获取response的header
        String responseHeadTime = response.header("time").toString();return response;
    }
}

2、生成Retrofit对象

?

1 2 3 4 5

Retrofit retrofit = new Retrofit.Builder()                                 .baseUrl("http://xxxxxxxxxxxxxxxxxxxx")                                 .client(httpClient.build())                                 .addConverterFactory(GsonConverterFactory.create(date, httpHeadInfo))                                 .build();

1	GsonConverterFactory是附加器（按照设计模式，好像是AOP，面向切面编程）<br><br><br>3、body加密的时候，写在GsonConverterFactory的 requestBodyConverter 里<br><br>注意，相对于ASP.Net mvc来说，接口里边传入@Body的话呢，在服务器端是接收不到的。你需要把这些东西通过 FormBody重新赋值一下<br><br>

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

@Override public RequestBody convert(T value) throws IOException {       if (value instanceof BaseSign) {         String jsonstr = gson.toJson(value);           String key = "android";         Logger.debug("xxx", "AES加密前：" + jsonstr + "     key=" + key);         key = Md5Util.parseStrToMd5L32(key);         String newRequest = AESUtils.initEncode(jsonstr, key);           return new FormBody.Builder().add("data", newRequest).build();       } else {         //这里是不加密的         return RequestBody.create(MEDIA_TYPE, "");     }
