我需要在我的Android应用上构建一个流量监控器,我需要存储我通过改造发送和接收的所有json的大小。使用日志我可以看到它的实际大小,但我还没有找到获取此信息的方法,所以我可以保存它。我无法获得response.raw,因为它已被解析为我的类。有没有办法实现这一目标?
编辑:标记的vadkou答案是最佳答案。
我没有创建新的拦截器,而是传递了lamda表达式:
httpClient.addInterceptor( chain -> {
okhttp3.Request request = chain.request();
okhttp3.Response response = chain.proceed(request);
if(request.body()!=null) {
long requestLength = request.body().contentLength();
Log.e("SERVICE GENERATOR", " CONTENT LENGTH" + requestLength);
}
long responseLength = response.body().contentLength();
Log.e("SERVICE GENERATOR", " RESPONSE LENGTH" + responseLength);
return response;
});

Retrofit 2在内部使用OkHttp,你可以配置OkHttp,而不必像Vaiden的回答那样通过在构建适配器时添加自定义拦截器来获取原始HTTP响应,如下所示:
private Retrofit createRetrofit() {
return new Retrofit.Builder()
.baseUrl(END_POINT)
// .addConverterFactory(...)
// .addCallAdapterFactory(...)
.client(createClient())
.build();
}
private OkHttpClient createClient() {
OkHttpClient.Builder okHttpClientBuilder = new OkHttpClient.Builder();
okHttpClientBuilder.addInterceptor(createYourInterceptor());
return okHttpClientBuilder.build();
}
Interceptor接口允许您为每个请求访问请求正文。
@Override
public Response intercept(Chain chain) throws IOException {
Request request = chain.request();
// do what you want with request.body().contentLength();
return chain.proceed(request);
}

为此,您需要创建自定义的interecptor 请参考以下示例
import java.io.IOException;
import okhttp3.Interceptor;
import okhttp3.Request;
import okhttp3.Response;
public class CustomIntercepter implements Interceptor {
@Override
public Response intercept(Chain chain) throws IOException {
Request request = chain.request();///
Response response = chain.proceed(request);
// for request size
long requestLength = request.body().contentLength();
// for response size
long responseLength = response.body().contentLength();
return response;
}
}
`
现在创建Retrofit对象
OkHttpClient provideOkHttpClient(CustomIntercepter customIntercepter) {
OkHttpClient.Builder okHttpClient = new OkHttpClient.Builder();
okHttpClient.cache(cache);
okHttpClient.addInterceptor(customIntercepter);
return okHttpClient.build();
}
Retrofit provideRetrofit(Gson gson, OkHttpClient okHttpClient) {
Retrofit retrofit = new Retrofit.Builder()
.addConverterFactory(GsonConverterFactory.create(gson))
.baseUrl(SERVER_URL)
.client(okHttpClient)
.build();
return retrofit;
}

您应该尝试访问原始HTTP响应(Get raw HTTP response with Retrofit):
您从Response对象开始。
此对象具有.raw()
方法,该方法返回实际HTTP层的响应,
以okhttp3.Response对象的形式。调用.body()
会给你一个ResponseBody对象,它封装了原始响应。
您可以致电.contentLength()
来获取回复的长度。
