什么会导致我的模型突然在HttpWebRequest (Google Chrome)上变为空
本文关键字：Chrome Google HttpWebRequest 我的 模型 突然 什么 | 更新日期: 2023-09-27 18:10:36
我使用HttpWebRequest将支付细节传达给支付处理器并接收响应。当封装此请求的方法被命中时，模型被传入，但一旦请求发生，模型就突然变为空。也就是说，这发生在谷歌浏览器，但我相信这里有一个更深层次的问题。我也只在生产服务器上观察到这种行为，但我无法在localhost下调试它。对于那些使用过支付处理程序的人，我使用了类似的方法将付款发布到Authorize。网无问题。也许这是一个与如何将信息发布到另一个服务器以及以何种格式发布相关的问题。

错误信息是这样的System.NullReferenceException: Object reference not set to an instance of an object. at namespace.MerchantOne.Charge(PaymentModel paymentSession) at namespace.Controllers.PaymentController.Confirmation(String restartBtn, String prevBtn, String nextBtn)
老实说，它可能是另一个对象变为null或未初始化，但现在，我能想到的是我的PaymentModel在使用后丢失了。
我也有类似的问题。我得到了一个无效的回应，从贝宝的购物车项目和其他数额。原来，当接收回响应时，我使用的是IP地址，但在发送请求时，我使用的是localhost。请检查一下是不是这个问题。
所以，事实证明…Chrome浏览器的一些完全愚蠢的东西。我一整天都在绞尽脑汁。我的代码很好，服务器上的会话设置也很好。
404在woff/woff2文件中找不到。我在我的项目中使用font-awesome，它正在寻找的两个资源抛出了404/未找到，这杀死了我的asp.net会话。
这是最终解决我的问题…向服务器添加.woff和.woff2 MIME类型。
为什么@font-face在woff文件上抛出404错误?
感谢所有试图帮助我的人。
