在调用Get in Rest WCF时响应的截断数据。 [英] Truncated data coming in response while calling Get in Rest WCF.

问题描述

我对Restful WCF服务很新，所以请耐心等待。我正在尝试构建一个简单的RESTful WCF服务，该服务返回一个学生列表作为json响应。



响应中约3842条记录显示当我调用相同的方法时浏览器但在实际列表中包含大约9000条记录。



为什么响应被截断？

解决方案

hi one两件事....



尝试在你的web.config上设置maxJsonLength属性：



< pre lang =xml> < configuration >
< system.web.extensions >
< 脚本 >
< webservices >
< jsonserialization maxjsonlength = 此处为大号 / < span class =code-keyword>>
< / webservices >
< / scripting >
< / system.web.extensions >
< / configuration >

或因为它是WCF，您可能需要查看服务行为。尝试设置maxitemsinobjectgraph属性。

 <  行为 >  
 <   servicebehaviors  >  
 <   behavior     name   =  metadataBehavior >  
 <   servicemetadata     httpgetenabled   =  true    httpgeturl   =     /  >  
 <   servicedebug     includeexceptiondetailinfaults   =  false    /  >  
 <   datacontractserializer     maxitemsinobjectgraph   =   2147483646    /  >  
 <   / behavior  >  
 <   / servicebehaviors  >  
 <   / behavior  >

I am pretty new to Restful WCF services so bear with me. I am trying to build a simple RESTful WCF service that returns a List of Students as json response.

In Response Approx 3842 Records are Showing when i invoke the same method in Browser but in actual List contains approx 9000 records.

Why response is truncated?

解决方案

hi one of two things....

Try setting maxJsonLength property on your web.config:

<configuration>
   <system.web.extensions>
       <scripting>
           <webservices>
               <jsonserialization maxjsonlength="Large number here" />
           </webservices>
       </scripting>
   </system.web.extensions>
</configuration>

or because it is WCF you may want to look at the service behaviours. Try setting the maxitemsinobjectgraph property.

<behaviors>
        <servicebehaviors>
            <behavior name="metadataBehavior">
                <servicemetadata httpgetenabled="true" httpgeturl="" />
                <servicedebug includeexceptiondetailinfaults="false" />
                <datacontractserializer maxitemsinobjectgraph="2147483646" />
            </behavior>
        </servicebehaviors>
    </behaviors>
