为什么第二个请求失败了？我可以更改 RestSharp headers 的顺序吗？
Why is the second request failing? Can I change the order of RestSharp headers?
我正在尝试与我的家 mode/route/gateway 连接，它有一个使用 CWMP (TR-69) SOAP 协议（通过 javascript 客户端）的网络 UI管理配置。
我正在尝试复制（不需要完全相等，但只是为了工作）js 客户端使用 RestSharp 完成的第一个请求，但它总是失败并出现 500 内部错误。
这是来自 javascript 的 RAW 请求：

Content-Type: text/xml; charset="utf-8"
Accept: application/xml, text/xml, */*; q=0.01

我认为这两个请求基本相同，但是第二个请求失败了。
这里唯一的区别似乎是 header 命令、用户代理和缺少的方法 header.
如何在 RestSharp 中更改 header 的顺序？

我确实尝试使用 RestSharp 发出上述请求：
所以，这是代码：
Function GetLoggedUser() As RestSharp.RestResponse
Dim T As New TokenAndCookieGetter
Dim xaction As String = "LoggedUser"
Dim xbody As String = Envelope(T.DM_COOKIE, xaction)
Dim req = New RestSharp.RestRequest("/data_model.cgi", RestSharp.Method.POST)
req.AddHeader("Origin", "http://vodafone.station")
req.AddHeader("Method", "POST")
req.AddHeader("Accept", "application/xml, text/xml, */*; q=0.01")
req.AddHeader("X-Requested-With", "XMLHttpRequest")
req.AddHeader("SOAPServer", "")
req.AddHeader("SOAPAction", "cwmp:" + xaction)
req.AddHeader("DNT", "1")
req.AddHeader("Referer", "http://vodafone.station/main.cgi?page=about.html")
req.AddHeader("Accept-Encoding", "gzip, deflate")
req.AddHeader("Accept-Language", "it-IT,it;q=0.8,en-US;q=0.6,en;q=0.4")
'Cookie is already set in T.CLIENT, by assigning a CookieContainer.
req.AddHeader("Host", "vodafone.station")
req.AddParameter("text/xml; charset=""UTF-8""", xbody, RestSharp.ParameterType.RequestBody)
Return T.CLIENT.Execute(req)
End Function
这是相应的请求，不幸失败了：

更新 3 我解决了这个问题。
所以我终于找到了问题所在。不是 header.
是坏字符转义的情况。真丢脸。
Dim envelope As String = String.Format("<cwmp:{0} xmlns="">{1}</cwmp:{0}>", action, body)
我没有转义双引号，所以请求总是会因为错误的 XML（xmlns=" 属性）而导致 500 错误。
这是最终的工作请求：
