grails - 从 grails 向 mailchimp 2.0 发送 post 请求

Question

目前，我正在将我的 grails 项目与 mailchimp 2.0 API 集成(我们目前使用来自 grails-mailchimp 插件的 1.2 版)
当我向 mailchimp 端点发送带有 json 数据的发布请求时，我总是收到此错误“HTTP/1.1 302 已临时移动”。我该如何解决？

这是我使用 HTTPBuilder 的代码

def twitter = new RESTClient( "https://us4.api.mailchimp.com/2.0/lists/member-info.json")
def resp = twitter.post(
        path : '/',
        body : body1,
        requestContentType : ContentType.JSON )

assert resp.status == 200

我的日志记录:

好像我发送的是 http，而不是 https(因为代码 302 Moved Temporarily only for HTTP 协议(protocol))，不是吗？如果是，我该如何解决？

最后我可以找到一种发送到mailchimp的方法，它只是跟随httpbuilder tutorial

    def emails = []
    emails.add(['email': email_address])
    def body1 = ['id' : id, 'emails' : emails, 'apikey': apiKey]
    def http = new HTTPBuilder("https://us4.api.mailchimp.com/2.0/lists/member-info.json")
    http.request(Method.POST, ContentType.JSON ) { req ->
        body = body1
        response.success = { resp, json ->
            assert resp.statusLine.statusCode == 200
            println json
        }
    }
