OkHttp的拦截器Interceptor

1.请求在连接中添加头信息

自定义拦截器如下：

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()//注意不要写错这行代码。         return chain.proceed(request);     } }

添加截器添加到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();
