[csharp]
格式化程序尝试对消息反序列化时引发异常: 尝试对参数 https://tempuri.org/ 进行反序列化时出错: formDataXml。InnerException 消息是“反序列化对象 属于类型 System.String 时出现错误。读取 XML 数据时，超出最大字符串内容长度配额 (8192)。通过更改在创建 XML 读取器时所使用的 XmlDictionaryReaderQuotas 对象的 MaxStringContentLength 属性，可增加此配额。 第 137 行，位置为 76。”。有关详细信息，请参阅 InnerException。
网上一搜索，答案基本得到解决，可我的问题就是不能解决(主要是细节打败了我)，按照网上的文章进行服务器端修改配置如下：
[html]
<binding name="HttpBinding" <span style="color:#ff0000"><strong>maxReceivedMessageSize</strong></span>="2097152">
<readerQuotas maxDepth="32" <span style="color:#ff0000"><strong>maxStringContentLength</strong></span>="2097152" maxArrayLength="2097152" maxBytesPerRead="2097152" maxNameTableCharCount="2097152" />
<security mode="None"></security>
</binding>
其实这里主要的配置是两个：maxReceivedMessageSize、maxStringContentLength；
网上提到还需要配置客户端，其实如果是报上面错误就不要管客户端了，因为如果是客户端调用WCF报错，就不是读取XML数据超时，而是明确的错误提示，如下：
[csharp]
已超过传入消息(1024)的最大消息大小配额。若要增加配额，请使用相应绑定元素上的 MaxReceivedMessageSize 属性。
所以这篇文章提到的错误基本与客户端无关。
一般情况下，安装上面的修改就可以解决问题了，但是我的WCF还是报错，没办法，只能继续找，无意间发现服务器端WCF配置有点异常，不用登录验证的WCF接口有用到bindingConfiguration，但是需要验证的WCF接口就没有配置该属性，如下代码：
[html]
<bindings>
<wsHttpBinding>
<span style="color:#ff0000"><binding name="HttpBinding" maxReceivedMessageSize="2097152">
<readerQuotas maxDepth="32" maxStringContentLength="2097152" maxArrayLength="2097152" maxBytesPerRead="2097152" maxNameTableCharCount="2097152" />
<security mode="None"></security>
</binding></span><span style="background-color:#f0f0f0"><binding name="HttpBinding" maxReceivedMessageSize="2097152"> <readerQuotas maxDepth="32" maxStringContentLength="2097152" maxArrayLength="2097152" maxBytesPerRead="2097152" maxNameTableCharCount="2097152" /> <security mode="None"></security> </binding></span>
</wsHttpBinding>
</bindings>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
<services>
<service name="Achievo.MMIP.WMP.WebService.WMPProcService" behaviorConfiguration="wmpWcfBehavior">
<span style="color:#ff0000"><strong><endpoint address="" binding="wsHttpBinding" contract="Achievo.MMIP.WMP.WebServiceIService.WMPServiceProcIService"></strong>
</span> <identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
<service name="Achievo.MMIP.WMP.WebService.WMPGetFormDataService" behaviorConfiguration="wmpWcfFormDataBehavior">
<span style="color:#ff0000"><strong><endpoint address="" binding="wsHttpBinding" bindingConfiguration="HttpBinding" contract="Achievo.MMIP.WMP.WebServiceIService.IWMPGetFormDataIService"></strong>
</span> <identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>
注意红色部分的配置，大伙可以对比一下，就发现其中一个缺少bindingConfiguration配置；如果这个时候，把缺少的部分补上，和另外一个配置一样，WCF就会出错，这里我的初步判断是：name="Achievo.MMIP.WMP.WebService.WMPProcService"是必须要验证登录才能访问，所以不能绑定上面的匿名访问的配置，简单说就是规定是验证就不能在配置为匿名；所以把配置修改为如下：
[html]
<bindings>
<wsHttpBinding>
<span style="color:#ff0000"><strong><binding name="HttpBinding" maxReceivedMessageSize="2097152">
<readerQuotas maxDepth="32" maxStringContentLength="2097152" maxArrayLength="2097152" maxBytesPerRead="2097152" maxNameTableCharCount="2097152" />
<security mode="None"></security>
</binding>
<binding name="HttpBinding1" maxReceivedMessageSize="2097152">
<readerQuotas maxDepth="32" maxStringContentLength="2097152"/>
</binding></strong></span>
</wsHttpBinding>
</bindings>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
<services>
<service name="Achievo.MMIP.WMP.WebService.WMPProcService" behaviorConfiguration="wmpWcfBehavior">
<strong><span style="color:#ff0000"><endpoint address="" binding="wsHttpBinding" <span style="font-size:18px">bindingConfiguration="HttpBinding1"</span> contract="Achievo.MMIP.WMP.WebServiceIService.WMPServiceProcIService"></span></strong>
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
<service name="Achievo.MMIP.WMP.WebService.WMPGetFormDataService" behaviorConfiguration="wmpWcfFormDataBehavior">
<strong><span style="color:#ff0000"><endpoint address="" binding="wsHttpBinding" bindingConfiguration="HttpBinding" contract="Achievo.MMIP.WMP.WebServiceIService.IWMPGetFormDataIService"></span></strong>
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>
在验证，OK，通过。
