编写基于WCF服务的程序时,向WCF服务端发送一长串的HTML源码,结果客户端收到提示如下:
格式化程序尝试对消息反序列化时引发异常: 对操作“AddArticle”的请求消息正文进行反序列化时出现错误。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 64 行,位置为 79。
主要是maxStringContentLength和maxReceivedMessageSize的设置会影响到消息的发送和接收,于是全部改为2MB大小,即2097152。
客户端app.config修改:
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_ShareService" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="2097152"
messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
useDefaultWebProxy="true">
<!-- Reset maxStringContentLength for deserialize -->
<readerQuotas maxDepth="32" maxStringContentLength="2097152" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None"
realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
</bindings>
服务端web.config修改:
<system.serviceModel>
<!-- add for the message size -->
<bindings>
<basicHttpBinding>
<binding name="NewBinding2MB" maxReceivedMessageSize="2097152">
<readerQuotas maxStringContentLength="2097152" />
</binding>
</basicHttpBinding>
</bindings>
<!-- add for the message size -->
