java - okhttp 怎么才能post一个空的requestbody

Question

新浪微博的OAuth认证，需要拿着code来获取Accesstoken，官方给的范例如下

https://api.weibo.com/oauth2/access_token?client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET&grant_type=authorization_code&redirect_uri=YOUR_REGISTERED_REDIRECT_URI&code=CODE

接口的文档地址：access token

根据官方的文档，这个接口需要post方法，进行请求

String postUrl = "https://api.weibo.com/oauth2/access_token?client_id=" + APPKEY + "&client_secret="
                + APPSECRET + "&grant_type=authorization_code&redirect_uri=" + REDIRECT_URI
                + "&code=" + code;

Request mRequest = new Request.Builder().post(null).url(postUrl).build();

结果报错信息显示，post方法中必须得有request body参数

请问这种情况我应该怎么做呢？

    .post(okhttp3.internal.Util.EMPTY_REQUEST)
    .url(postUrl)
    .build();

Request mRequest = new Request.Builder()
    .post(RequestBody.create(null, ""))
    .url(postUrl)
    .build();
