Javascript 在ASP.NET中集成支付网关

在基于asp.net Web表单的网站中集成支付网关。示例代码文档示例仅用php编写

我不知道如何前进，因为文档似乎没有多大帮助

响应

StatusCode:417，ReasonPhrase:“期望失败”，版本：1.1，内容：System.Net.Http.StreamContent，标题：{连接：关闭日期：2017年1月17日星期二10:52:30 GMT服务器：Apache内容长度：364内容类型：text/html；charset=iso-8859-1}

由于无法共享，我已更改了

return\u auth

和

ivp\u store

。任何正确的做法都会大有裨益

我对这些文档感到困惑，因此无法正确地进行操作。他们的网站上似乎没有任何.net示例，而是有我不懂的PHP插件

我找到了wooCommerce插件的另一个例子，它是PHP

如果我使用邮递员并向

我得到了

因此，我猜您构建请求的方式是错误的（尤其是

，它应该是

application/x-www-form-urlencoded

，而不是

）

由于我没有

仅支持100继续期望值

HttpClient

默认情况下会发送一个

Expect:100 continue

头，这显然会干扰您尝试连接的服务器。

示例显示了一个使用cURL的简单HTTP请求，您到底不知道什么？@komo这是文档中显示的示例，但我需要在基于asp.net网络表单的网站中使用相同的方法。我正试图使用HTTPClient执行此操作，但始终出现错误417。@komo，我已更新了问题基本上您没有正确阅读文档，并且在没有正确理解文档的情况下尝试跳转到代码中。它的逻辑将帮助您，而不是技术。JsonConvert.SerializeObject（str）应该是JsonConvert.SerializeObject（obj），它将序列化对象并为order.JSON API创建所需的JSON。你在“str”中的值是你将从API中获得的，它只是一个Chrome扩展。我想我可以从

.NET

使用

HttpClient

得到同样的结果。你能分享这段C代码吗？这样我也可以进行测试。我也试过邮递员，但我不能让它工作，我一直在变差Request@Learning-为您的问题发布了解决方案。感谢我将尽我所能，我正面临着结果集的问题，因为我必须在KeyValuePair中传递多个数据类型，因为我的帧返回显示为空白，我确信这是由于我传递的单个数据类型造成的。我正在使用“
