我遇到了类似的问题。来自 Swift 的请求正文与 Postman 请求相同，我收到了来自 Django Rest Framework API 主机的错误请求响应。

Postman 添加值为 Content-Type 的 application/json 标头，如果这是您指定的正文类型。我尝试在我的 Swift iOS 请求客户端（请参阅 this answer FMI）中自己设置它，现在我得到了成功的响应。

我使用的相关片段：

var request = URLRequest(url:renderedUrl)
request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Accept")

Http post请求在postman中工作正常，但在iOS中没有？
