关于微信小程序读取.net webservice的问题

[pmmiao]

.net 的webservice，是同一个webservice，当用户名密码正确时返回：

当用户名密码错误时返回：

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<string xmlns="http://www.plcing.com/">获取设备状态数据：用户不存在或用户名密码错误！</string>


在微信小程序中读取，对于用户名密码错误的，可以读取到正常的数据，但当用户名密码正解时，就返回错误：Object {Message: "无效的 JSON 基元: XXX。", StackTrace: " 在 System.Web.Script.Serialization.JavaScriptObj…Context context, WebServiceMethodData methodData)", ExceptionType: "System.ArgumentException"}ExceptionType:"System.ArgumentException"


请问有人知道吗？感谢！！

ArgumentException 这个是参数空导致的，仔细检查你的代码。服务端的 参数你有没有传送的。

我想咨询下后面的解析wx是怎么完成的，楼主能提供下么？ 关于您这的问题是在header里面要设置下 header: {'Content-Type': 'application/x-www-form-urlencoded'}

先用调试工具看下，你的.NET WEBSERVICE 是否正常。
