Header
How to Add header to Every Request
添加统一通用header， 不会覆盖前面的header
okHttpClient.interceptors().add(new Interceptor() {
@Override
public Response intercept(Interceptor.Chain chain) throws IOException {
Request original = chain.request();
// Request customization: add request headers
Request.Builder requestBuilder = original.newBuilder()
.addHeader("header-key", "value1")
.addHeader("header-key", "value2");
Request request = requestBuilder.build();
return chain.proceed(request);
}
});添加统一通用header， 会覆盖前面的header
okHttpClient.interceptors().add(new Interceptor() {
@Override
public Response intercept(Interceptor.Chain chain) throws IOException {
Request original = chain.request();
// Request customization: add request headers
Request.Builder requestBuilder = original.newBuilder()
.header("headerkey", "header-value"); // <-- this is the important line
Request request = requestBuilder.build();
return chain.proceed(request);
}
});Parameters
How to Add Query Parameters to Every Request
OkHttpClient.Builder httpClient =
new OkHttpClient.Builder();
httpClient.addInterceptor(new Interceptor() {
@Override
public Response intercept(Chain chain) throws IOException {
Request original = chain.request();
HttpUrl originalHttpUrl = original.url();
HttpUrl url = originalHttpUrl.newBuilder()
.addQueryParameter("apikey", "your-actual-api-key")
.build();
// Request customization: add request headers
Request.Builder requestBuilder = original.newBuilder()
.url(url);
Request request = requestBuilder.build();
return chain.proceed(request);
}
});
