cURL 和 Postman HTTP POST 工作，但 Golang 请求失败，状态为 400

问题内容

我正在尝试通过 HTTP POST 以 JSON 格式发送 GooglePay 令牌。该请求在 cURL 和 Postman 上工作正常，但当我尝试使用 Go HTTP 请求时，服务器抱怨数据格式无效，HTTP 响应状态代码为 400。

cURL

我尝试使用 nc 打印来自 cURL、Postman 和 GoLang 的所有 HTTP 标头和正文，它们看起来相同。我还操纵了用户代理以保持一致，但还没有运气。感谢任何帮助。

长答案

天知道什么原因，服务器只接受Transfer-Encoding：chunked。所以当您发送“正常”请求时，它看起来像这样失败：

POST /cardsecure/api/v1/ccn/tokenize HTTP/1.1
Host: fts-uat.cardconnect.com
Content-Length: 1373

当您添加上述代码时，它看起来像这样并通过：

POST /cardsecure/api/v1/ccn/tokenize HTTP/1.1
Host: fts-uat.cardconnect.com
Transfer-Encoding: chunked
