JSON限制为1180个字符 [英] JSON Limited to 1180 Characters

问题描述

我有一个简单的JavaScript JSON请求，该请求对要通过JSON请求发送到我的C#Web服务器的对象进行字符串化处理.

I have a simple JavaScript JSON request which stringify's an object to send via a JSON request to my C# Web server.

每当stringy返回的字符串超过1180个字符时，服务器上都不会调用WebMethod.

Whenever the string returned by stringy is over 1180 characters, the WebMethod is not called on the server.

据我了解，客户端可以通过JSON发送多少字符串数据没有限制.我知道限制是在服务器端，试图接受参数化的请求.

From my understanding, there is no limit on how much string data the client can send via JSON. I understand that the limitation is on the server end, trying to accept the paramaterized request.

web.config中是否可以增加1180的限制?

Is there somewhere in the web.config that I can increase this limit of 1180?

我当前的配置；

<?xml version="1.0"?>
<configuration>
  <connectionStrings>
    <add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;initial catalog=aspnetdb" providerName="System.Data.SqlClient"/>
    <add name="ApplicationServices2" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;initial catalog=trimweb" providerName="System.Data.SqlClient"/>
    <add name="ApplicationServices3" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;initial catalog=Customers" providerName="System.Data.SqlClient"/>
    <add name="ApplicationServices4" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;initial catalog=OrderUpdate;User ID=test1;Password=test1;" providerName="System.Data.SqlClient"/>
  </connectionStrings>
    <system.serviceModel>
      <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

      <behaviors>
        <endpointBehaviors>
          <behavior name="webHttpBehavior">
            <webHttp />
          </behavior>
        </endpointBehaviors>
      </behaviors>
      <bindings>
        <webHttpBinding>
          <binding name="webHttpBindingWithJsonP" crossDomainScriptAccessEnabled="true" />
        </webHttpBinding>

      </bindings>
      <services>
        <service name="ServiceSite.CustomersService">
          <endpoint address="" binding="webHttpBinding"
                    bindingConfiguration="webHttpBindingWithJsonP" contract="ServiceSite.CustomersService"
                    behaviorConfiguration="webHttpBehavior"/>
        </service>
      </services>
    </system.serviceModel>

    <system.web>
        <compilation debug="true" targetFramework="4.0" />
    </system.web>
    <system.webServer>
      <modules runAllManagedModulesForAllRequests="true"/>
    </system.webServer>

</configuration>

推荐答案

您需要将webHttpBinding更改为以下内容:

Youll need to change your webHttpBinding to something like the below:

   <webHttpBinding>
      <binding name="webHttpBindingWithJsonP" crossDomainScriptAccessEnabled="true" maxReceivedMessageSize="20000000" maxBufferSize="20000000" maxBufferPoolSize="20000000"/>
      <readerQuotas maxDepth="32" maxArrayLength="200000000" maxStringContentLength="200000000"/>
   </webHttpBinding>

在此处查看<webHttpBinding>的文档

注意:在ASP.NET兼容模式下，仅增加此值是不够的.您还应该增加httpRuntime的值(请参见 httpRuntime ).

Note: Increasing this value alone is not sufficient in ASP.NET compatible mode. You should also increase the value of httpRuntime (see httpRuntime).

这应该类似于:

<httpRuntime 
   maxQueryStringLength = "2048"
   maxRequestLength="4096"
   maxUrlLength = "260"
   requestLengthDiskThreshold="80"/>

(根据需要增加金额)
