Sendgrid将电子邮件添加到列表中，在grails中收到错误的请求

我正试图使用以下代码向sendgrid发送请求，以便将电子邮件添加到列表中，但我总是收到404:错误请求

def chttps = new HTTPBuilder('https://api.sendgrid.com/api/newsletter/lists/email/add.json?&api_user=myUser&api_key=myKey')

    chttps.request( Method.POST, ContentType.JSON ) { req ->
        headers.'Content-Type' = 'application/json'
        body = [
            list : 'testlist',
            data : [email : '123Ex@exm.pl', name : '123Ex' ]
        ]

        response.success = { resp, json ->
            // response handling here
        }
        // handler for any failure status code:

    }

以下是我得到的错误： 为了在单个请求中添加多封电子邮件，我尝试使用以下格式：

data=%5B%7B%22email%22%3A+%22example1112%40gmail.com%22%2C%22name%22%3A+%22112example%22%7D%2C%7B%22email%22%3A+%22example2222%40gmail.com%22%2C%22name%22%3A+%22222example%22%7D%5D 
//encode for :: [{"email": "example1112@gmail.com","name": "112example"},{"email": "example2222@gmail.com","name": "222example"}]

但我经常遇到以下例外，有没有办法添加多封电子邮件

看起来您正在尝试发布JSON负载。SendGrid API目前不支持JSON有效负载，因此您需要将有效负载作为POST数据发送

解决了这个问题，结果表明服务器不接受json数组，相反，它接受查询字符串中的多个data[]元素，所以您只需调用这个：

sendgrid.com/api/newsletter/lists/email/add.json?list=testlist&data[]={"email"+%3A+"123Ex1%40exm.pl"%2C+"name"+%3A+"123Ex1"}&data[]={"email"+%3A+"123Ex2%40exm.pl"%2C+"name"+%3A+"123Ex2"}&api_user=myUser&api_key=myKey

希望这对其他人有所帮助。

thanx对于提示，我对数据部分进行了编码，并根据它更新了代码。请查看有问题的编辑，但我仍然无法添加多封电子邮件请求。如果可以，我将投赞成票，但我需要声誉
