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>

最后单元测试，通过！爽！
