响应最大压缩c#
早上好，我在.net中找到了一个解决方案，我调用了saber讨价还价查找器max的Web服务。现在我想下载压缩信息，但响应对象返回null。我了解到您必须在SendRequest之前和Receivereply之后调用接口IClientMessageInspector，但我不知道如何继续。有人会给出一个例子或解决方案吗？谢谢服务的响应无法处理压缩响应，因此，是的，您必须在继续解压之前放置中间件以处理解压 首先，您需要将BFM WSDL作为服务导入，而不是作为web服务导入，因此：响应最大压缩c#,c#,sabre,C#,Sabre,早上好，我在.net中找到了一个解决方案，我调用了saber讨价还价查找器max的Web服务。现在我想下载压缩信息，但响应对象返回null。我了解到您必须在SendRequest之前和Receivereply之后调用接口IClientMessageInspector，但我不知道如何继续。有人会给出一个例子或解决方案吗？谢谢服务的响应无法处理压缩响应，因此，是的，您必须在继续解压之前放置中间件以处理解压 首先，您需要将BFM WSDL作为服务导入，而不是作为web服务导入，因此： 右键单击“服务引

希望这有帮助 你什么都不用做。WCF支持HTTP压缩。Sabre在上启用HTTP压缩，而不是。不要使用他们的自定义压缩调用-它仍然是GZip，它压缩身体的一部分，但您必须编写代码来解压缩它。PS Fiddler可以解压缩压缩的HTTP响应。在开发过程中，检查响应、检查内容、错误消息等是必不可少的。如果您使用自定义压缩，那么最终将得到一个blob，您必须在检查之前在代码中对其进行解压缩。使调试和测试变得有点困难
