OkHttp的拦截器Interceptor

1.请求连接中添加头信息

先自定义一个拦截器如下：public class DefaultHeaderInterceptor implements Interceptor {

@Override
public Response intercept(Chain chain) throws IOException {
Request originalrequest = chain.request();//原始request
Headers headers = new Headers.Builder()
.add("name", "jason")
.add("age", "27")
.add("token", "dfedsdfsdfffdd12dsef123sdfef1s2dfe")
.build();//构造一个Headers
Request request = originalrequest.newBuilder().headers(headers).build();//注意这行代码别写错了
return chain.proceed(request);
}
}添加拦截器到okhttp：
OkHttpClient okHttpClient = new OkHttpClient.Builder()
.addNetworkInterceptor(httpLoggingInterceptor)
.addInterceptor(new DefaultHeaderInterceptor())//添加拦截器
.connectTimeout(5, TimeUnit.SECONDS)
.readTimeout(5, TimeUnit.SECONDS)
.build();
