WCF 配置文件中的MaxStringContentLength & MaxReceivedMessageSize_.NET_编程开发_程序员俱乐部

中午测试员在测试系统模块时发现无法通过WCF从服务器下载数据，检查配置文件后，建议开发人员修改站点的WEB.CONFIG文件，具体修改对比如下：

旧的：

<binding name="BasicHttpBinding_ICentaMiddleService" 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="65536"

          messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"

          useDefaultWebProxy="true">

          <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"

            maxBytesPerRead="4096" maxNameTableCharCount="16384" />

          <security mode="None">

            <transport clientCredentialType="None" proxyCredentialType="None"

              realm="" />

            <message clientCredentialType="UserName" algorithmSuite="Default" />

          </security>

</binding>

 

新的：

<binding name="BasicHttpBinding_ICentaMiddleService" 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="9223372036854775807"

          messageEncoding="Text" textEncoding="utf-8" transferMode="Streamed"

          useDefaultWebProxy="true">

          <readerQuotas maxDepth="6553500" maxStringContentLength="2147483647"

            maxArrayLength="6553500" maxBytesPerRead="6553500" maxNameTableCharCount="6553500" />

          <security mode="None">

            <transport clientCredentialType="None" proxyCredentialType="None"

              realm="" />

            <message clientCredentialType="UserName" algorithmSuite="Default" />

          </security>

</binding>

 

注意这里修改的主要是maxReceivedMessageSize这个属性，解决了从服务器通过WCF下载大容量数据的问题。

 

下午测试人员继续测试，发现无法将数据通过WCF保存回服务器端。检查数据后发现，需要被保存的数据超过9K，而WCF服务器端使用的是binding="basicHttpBinding"这个数据绑定方式。思路打开，则应该是由于服务器端的接收的数据大小有限制。

当初次引用服务后，显示的服务器端binding="basicHttpBinding" 的最大上传数据容量是：

<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"

            maxBytesPerRead="4096" maxNameTableCharCount="16384" />

注意是maxStringContentLength="8192" ，那么判定，是由于绑定的默认值未被修改的缘故。接着修改服务器端的web.config配置文件。修改对比如下：

主要添加内容：

<bindings>

          <basicHttpBinding>

              <binding name="NewBinding0" maxReceivedMessageSize="6553600">

                  <readerQuotas maxStringContentLength="6553600" />

              </binding>

          </basicHttpBinding>

</bindings>

<endpoint address="" binding="basicHttpBinding" bindingConfiguration="NewBinding0"

              contract="CentaLine.CVM.Services.IPreAuthTransactionInfoService" />

 

 

最后单元测试，通过！爽！
