如何从头开始发出可用于 Oauth 和不同 api 调用的 HTTP 请求的基础知识

Question

有像 Retrofit 这样的框架，但我想学习基础知识，并且有很多可用的类，而且令人困惑，如果可用，请提及一些参考资料。

Answer 1

Retrofit uses OkHttp as default.

I personally include implementation 'com.squareup.okhttp3:okhttp:3.7.0 on dependencies

and I use it this way:

private Response post(String url, String body) throws IOException {
    RequestBody requestBody = RequestBody.create(MediaType.parse("application/json; charset=utf-8"), body);
    Request request = new Request.Builder().url(url).post(requestBody).build();
    return <yourOkHttpClient>.newCall(request).execute();
}

You have several tutorials on how to make the requests you want if you search for it.

You also have other, more robust frameworks, like Volley that is recently supported b Google, which you can use.
