【问题描述】：
我正在尝试使用以下代码向 sendgrid 发送请求以将电子邮件添加到列表，但我总是收到 404 : Bad request。
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：
Bad Request. Stacktrace follows:

找不到问题所在。请帮忙。
编辑1：
所以我尝试使用以下代码，它工作正常，但仍然无法在数据部分指定电子邮件列表：
def chttps = new HTTPBuilder('https://api.sendgrid.com/api/newsletter/lists/email/add.json?&api_user=myUser&api_key=myKey')
def dataa = "list=testlist&data=%7B%22email%22%3A%22examuttample%40gmail.com%22%2C%22name%22%3A%22uttam%22%7D"
chttps.post( body: dataa
) { resp ->
println "${resp}"
resp.headers.each {
println "${it.name} : ${it.value}"
}
println "${resp.data}"
println "http POST Success: ${resp.statusLine}"
}
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"}]
但我不断收到以下异常，有没有办法解决这个问题来添加多封电子邮件。
