okhttp拦截器添加请求头

新建一个类UserAgentInterceptor实现Interceptor

import java.io.IOException;import okhttp3.Interceptor;import okhttp3.Request;import okhttp3.Response;/** * 添加请求头 */public class UserAgentIntercepter implements Interceptor {    @Override    public Response intercept(Chain chain) throws IOException {        Request request =  chain.request().newBuilder()                .addHeader("key1","value")                .build();        return chain.proceed(request);    }}

在okhttputils封装类里添加 拦截器

 .addInterceptor(new UserAgentIntercepter())
