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。

req, _ := http.NewRequest(http.MethodPost, url, strings.NewReader(data))
req.Header.Set("Content-Type", "application/json")
client := &http.Client{}
resp, err := client.Do(req)
if err != nil {
panic(err)
}
fmt.Println("Response Status:", resp.Status)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。
添加此：
req.ContentLength = 0
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：
立即学习“go语言免费学习笔记（深入）”；
POST /cardsecure/api/v1/ccn/tokenize HTTP/1.1 Host: fts-uat.cardconnect.com Transfer-Encoding: chunked
以上就是cURL 和 Postman HTTP POST 工作，但 Golang 请求失败，状态为 400的详细内容，更多请关注php中文网其它相关文章！
