-- Ajax提交后，服务器报错：值不能为null,参数名s
一、Ajax提交部分：
mui.ajax(\'http://192.168.2.73/checkPhone.htm\',{
data:{phone:phone},
async: true,
dataType:\'json\',//服务器返回json格式数据
type:\'post\',//HTTP请求类型
timeout:10000,//超时时间设置为10秒；
headers:{\'Content-Type\':\'application/json\'},
success: function(rsp){
},
error:function(xhr,type,errorThrown){
//异常处理；
console.log(type);
}
});
data:{phone:phone},
async: true,
dataType:\'json\',//服务器返回json格式数据
type:\'post\',//HTTP请求类型
timeout:10000,//超时时间设置为10秒；
headers:{\'Content-Type\':\'application/json\'},
success: function(rsp){
},
error:function(xhr,type,errorThrown){
//异常处理；
console.log(type);
}
});
二、接受代码：
Dim e As RequestEventArgs = Args(0)
Dim jo As JObject = JObject.Parse(e.PlainText) \'解析JSON
Dim jo As JObject = JObject.Parse(e.PlainText) \'解析JSON
三、报错图片：

使用日志跟踪一下，看看都接收了什么数据：http://www.foxtable.com/bbs/dispbbs.asp?BoardID=2&ID=173590
\'\'记录接收的消息,方便分析,用于调试
Dim str As new StringBuilder
str.AppendLine("Headers:---------------")
For Each key As String In e.Request.Headers.AllKeys
str.AppendLine(key & " = " & e.Request.Headers(key))
Next
str.AppendLine("Headers:---------------")
str.AppendLine("host=" & e.Host)
str.AppendLine("port=" & e.Port)
str.AppendLine("path=" & e.Path)
str.AppendLine("HttpMethod=" & e.Request.HttpMethod)
str.AppendLine("poststring=" & e.PlainText)
\'str.AppendLine("ip=" & e.Request.RemoteEndPoint().Address.ToString())
str.AppendLine("url=" & e.Request.URL.ToString)
str.AppendLine("getValues:---------------")
For Each key As String In e.getValues.Keys
str.AppendLine(key & "=" & e.getValues(key))
Next
str.AppendLine("postValues:---------------")
For Each key As String In e.PostValues.Keys
str.AppendLine(key & "=" & e.PostValues(key))
Next
\'----------file
For Each key As String In e.Files.Keys
str.AppendLine(key & " 上传" & e.Files(key).Count & "个文件,分别是:")
For Each fl As String In e.Files(key)
str.AppendLine(fl)
Next
Next
\'----------file
