原文: The maximum string content length quota (8192) has been exceeded while reading XML data
问题场景:在我们WCF服务发布后,我们要确保服务端以及客户端的配置文件允许合适大小的传输设置。笔者在发布WCF服务时,服务端的绑定未做传输大小的设置(采用了默认,maxStringContentLength默认大小为8192),而我们在传输序列化的数据时,大小超过了这个限制。
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。
问题原因:服务端或者客户端关于传输大小的未做设置,maxStringContentLength默认大小为8192,实际传输大于8192,由此产生异常。
解决方案:
1.确定是客户端还是服务端的限制。
2.在客户端或服务器的做如下配置:
<binding name="xxx" maxReceivedMessageSize="2147483647"> <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" /> security> </binding>
代码中可修改如下:
MyServiceClient service = null; //MyServiceClient service = new MyServiceClient(); try { System.ServiceModel.Channels.CustomBinding bing = new System.ServiceModel.Channels.CustomBinding( new System.ServiceModel.Channels.BindingElement[]{ new BinaryMessageEncodingBindingElement(){ ReaderQuotas= new System.Xml.XmlDictionaryReaderQuotas { MaxDepth=2147483647, MaxStringContentLength=2147483647, MaxArrayLength=2147483647, MaxBytesPerRead=2147483647}}, new HttpTransportBindingElement() }); bing.Name = "CustomBinding_DataService"; EndpointAddress address = new EndpointAddress(http://www.xxx.com/MyService.svc); service = new MyServiceClient(bing, address); } catch (Exception ex) { throw ex; }
