How to get api request and api response time in Android Retrofit api using OkHttp Interceptor for each api?

Question

我得到了 Api 响应的响应时间，在调试时 BODY 中的 OkHttp3 拦截器的帮助下，但我想要每个 api 在发布版本上的服务器响应时间，我想上传它以在跟踪器中进行数据分析。 我已经尝试过这两种方法 1. Response.sentRequestAtMillis() 2. Response.receivedResponseAtMillis() 但我没有成功，所以请帮助我找到每个 api 的响应时间，或者通过计算 sendRequestAtMillis 和receivedResponseAtMillis 或通过直接获取响应 Api 示例中显示的(31ms) 。

Api 请求：-

D/OkHttp: --> POST http://api.globoapps.in/abc/updateUserDetail
D/OkHttp: Content-Type: application/json; charset=UTF-8
D/OkHttp: Content-Length: 208
D/OkHttp: {"androidId":"996e831d34ba64b0","id":4,"deviceToken":"abcd"}
D/OkHttp: --> END POST (208-byte body)

Api 响应：-

D/OkHttp: <-- 200 http://api.globoapps.in/abc/updateUserDetail (31ms)
D/OkHttp: Server: nginx/1.12.2
D/OkHttp: Date: Thu, 17 Oct 2019 09:30:24 GMT
D/OkHttp: Content-Type: application/json;charset=UTF-8
D/OkHttp: Transfer-Encoding: chunked
D/OkHttp: Connection: keep-alive
D/OkHttp: {"id":4,"status":"Success"}
D/OkHttp: <-- END HTTP (533-byte body)

代码（MainBaseApplication.java） ： -

   public static Retrofit getRetrofitInstance() {
        if (retrofit == null) {

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


            httpClient.readTimeout(30, TimeUnit.SECONDS);
            httpClient.connectTimeout(30, TimeUnit.SECONDS);
            httpClient.writeTimeout(30, TimeUnit.SECONDS);

            httpClient.addInterceptor(new Interceptor() {
                @Override
                public Response intercept(Chain chain) throws IOException {
                    Request original = chain.request();

                    Request.Builder builder = original.newBuilder();
                    builder.method(original.method(), original.body());
//                    builder.header("Accept", "application/json");
                    if (TOKEN.length() > 0)
                        builder.header("Authorization", TOKEN);
                    return chain.proceed(builder.build());
                }
            });

            HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
            if (BuildConfig.DEBUG) {
                interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
            } else {
                interceptor.setLevel(HttpLoggingInterceptor.Level.NONE);
            }
            httpClient.addInterceptor(interceptor);

            OkHttpClient client = httpClient.build();
//            Response response = client.newCall(request).execute();
//             tx = response.sentRequestAtMillis();
//            rx = response.receivedResponseAtMillis();
//            System.out.println("response time : "+(rx - tx)+" ms");
            Gson gson = new GsonBuilder()
                    .setLenient()
                    .create();

            retrofit = new Retrofit.Builder()
                    .baseUrl(WebAPI.BASE_URL)
                    .client(httpClient.build())
                    .addCallAdapterFactory(RxJava2CallAdapterFactory.createWithScheduler(Schedulers.io()))
                    .addConverterFactory(GsonConverterFactory.create(gson))
                    .build();
        }
        return retrofit;
    }

Answer 1

sentRequestAtMillis和receivedResponseAtMillis参数是指设备时间而不是服务器时间，如果您更改设备时间，它也会更改为此值。

根据https://square.github.io/okhttp/4.x/okhttp/okhttp3/-response/received-response-at-millis/它是某个时间缓存的时间戳，因此此方法不适用于您。

对于您的解决方案：您必须从 api 发送时间戳，您可以从 api 的响应中获取该参数并且您可以使用它。

如果您想要像31ms这样的毫秒响应，您可以覆盖 class HttpLoggingInterceptor.kt并检查 222 行号中的变量val tookMs ，这将返回您想要的 ms .. :)
