okhttp3怎么添加请求头

在OkHttp3中，可以通过拦截器Interceptor来添加请求头。以下是两种添加请求头的方法：

1. 使用Interceptor添加请求头[^1]：

OkHttpClient client = new OkHttpClient.Builder()
    .addInterceptor(new Interceptor() {
        @Override
        public Response intercept(Chain chain) throws IOException {
            Request originalRequest = chain.request();
            Request.Builder requestBuilder = originalRequest.newBuilder()
                .header("HeaderName", "HeaderValue")
                .header("AnotherHeaderName", "AnotherHeaderValue");
            Request newRequest = requestBuilder.build();
            return chain.proceed(newRequest);
        }
    })
    .build();

2. 使用Interceptor和Headers.Builder添加请求头：

OkHttpClient client = new OkHttpClient.Builder()
    .addInterceptor(new Interceptor() {
        @Override
        public Response intercept(Chain chain) throws IOException {
            Request originalRequest = chain.request();
            Headers.Builder headersBuilder = originalRequest.headers().newBuilder()
                .add("HeaderName", "HeaderValue")
                .add("AnotherHeaderName", "AnotherHeaderValue");
            Request newRequest = originalRequest.newBuilder()
                .headers(headersBuilder.build())
                .build();
            return chain.proceed(newRequest);
        }
    })
    .build();
