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。

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:
1 2 3 | 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:
1 2 3 | POST /cardsecure/api/v1/ccn/tokenize HTTP/1.1
Host: fts-uat.cardconnect.com
Transfer-Encoding: chunked
