Lyft API Android 整合？

Question

我正在尝试获取特定路径的 Lyft 价格。这是 Lyft 的身份验证 curl 请求，需要它才能请求价格：

curl -X POST -H "Content-Type: application/json" \
     --user "<client_id>:<client_secret>" \
     -d '{"grant_type": "client_credentials", "scope": "public"}' \
     'https://api.lyft.com/oauth/token'

我相信新的 android 不允许 HTTP 客户端，所以我对如何发出此请求感到非常困惑。我的请求总是失败。

private void LyftCabAPI(){//to get uber cab info in given source and destination
    class SendPostReqAsyncTask extends AsyncTask<String, Void, String> {
