asp.net 414（请求URI太长）

Question

如果我有一些数据，则注册完成。 但是如果我有多个数据，则注册没有，并且浏览器中显示错误“无法加载资源：服务器响应状态为414（请求URI太长）”

Web.Config

<security>
  <requestFiltering>
    <fileExtensions allowUnlisted="true">
      <remove fileExtension="."/>
      <add fileExtension="." allowed="true"/>
    </fileExtensions>
    <requestLimits maxUrl="65536" maxAllowedContentLength="4294967295" maxQueryString="2097151">
     <headerLimits>
              <add header="Content-type" sizeLimit="10000" />
           </headerLimits>
    </requestLimits>
  </requestFiltering>

JavaScript

 $.ajax({
