如何解决从我的 swift 应用程序发送 PUT 请求时出现的错误

Question

我得到了一个必须向其发送 put 请求的 URL。这些是正在发送的标头 - 正文也看起来像这样 - （第二张图片）

之前我在 Postman 上遇到了问题，因为在 cookies 标头中，它发送了一些 csrftoken，现在我从 Postman put 请求中删除了该标头，现在它工作正常，现在我必须在我的 Swift 中做同样的事情app - 但收到错误 403，实际上我硬编码了在 put 请求正文中发送的值，与邮递员上完全相同，我只在 put 请求中发送一个标头，附在下面的图片，我的 URL 也是同样的，我也打印出来了，这个错误是因为我在发送 put 请求时没有清除标头字段中的 cookie 吗？，我不明白如何解决这个问题，请帮忙

好吧，我解决了这个问题 - 基本上，我必须在标头中发送 csrftoken 值，如下 -

case .addTimeTable:
        return [
            "Content-Type": "application/json",
            "Cookie": "csrftoken=\(Utils.getValue(key: Constants.CSRFTOKENVALUE))"
        ]
