查询-
我收到HTML页面的回复.但是我想接收通过POST方法发送的Json
I receive a response as HTML Page. But I want to Receive the Json Which I was Send via POST method
JSON STRING-
{"d":{"accessKey":"Chennai","channelId":"1025"}}
编辑
我已将json字符串更改为{"accessKey":"Chennai"，"channelId":"1025"}，并更改了web方法来获取字符串.
I have changed the json string as {"accessKey":"Chennai","channelId":"1025"} and changed the webmethod to get the string.
[System.Web.Services.WebMethod]
public static string Get(string accessKey, string channelId)
{
return accessKey + channelId;
}
我收到了正确的channelId，accesskey值.但是我原来的弦很大.因此，我需要接收通过POST方法发送的同一Json字符串. bzs我只在接受部分.一旦我的客户通过调用此Websmethod发送Json字符串.谢谢.
I have received a correct channelId, accesskey values. But my original string is very big. so I need to receive same Json String which i send via POST method. bzs I am doing receiving part only. Once of my Client Send the Json String via Calling this Websmethod. Thanks.
编辑2-
根据梅兹·赛义德(Mez Said)的介绍，我已经包含ScriptMethod.但是它通过远程服务器返回了一个错误:(500)Internal Server Error.
As per Mez Said I have include the ScriptMethod. But It through The remote server returned an error: (500) Internal Server Error.
[System.Web.Services.WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public static string Get(string d)
{
return d;
}
推荐答案
可能达到了json的最大限制.尝试将其添加到您的web.config.
It is possible you reached the max limit for json. Try adding this to your web.config.
<configuration>
...
<system.web.extensions>
<scripting>
<webServices>
<jsonSerialization maxJsonLength="300000" />
</webServices>
</scripting>
</system.web.extensions>
</configuration>
