我有一个.Net Web服务(.asmx),它将一个Json字符串返回给我的客户端.但是,我的一些数据非常大,偶尔会出现此错误.
The length of the string exceeds the value set on the maxJsonLength property.
我已将maxJsonLength属性更改为2147483644,但它仍然无效.请帮忙……谢谢.
<system.web.extensions>
<scripting>
<webServices>
<jsonSerialization maxJsonLength="2147483644"/>
</webServices>
</scripting>
</system.web.extensions>
[WebMethod]
[ScriptMethod(UseHttpGet = true,ResponseFormat = ResponseFormat.Json)]
public void GetData(string login)
{
// throw an error on this line...
string result = new JavaScriptSerializer().Serialize(service.GetData(login));
Context.Response.Write(result);
}
解决方法
感谢Ed Gibbs和@NextInLine的建议.我做了如下修复,它现在就像一个魅力.我还从web.config中删除了“system.web.extensions”部分
[WebMethod]
[ScriptMethod(UseHttpGet = true,ResponseFormat = ResponseFormat.Json)]
public void GetData(string login)
{
// when the amount of data return is huge
var serializer = new JavaScriptSerializer();
// we need to do this.
serializer.MaxJsonLength = Int32.MaxValue;
var result = serializer.Serialize(service.GetData(login));
Context.Response.Write(result);
}
