编辑::使用MediaType“text/plain”时也会出现相同的错误。您的内容类型是text/xml,但实际内容只是“dfwa”。这不是有效的XML文档
(顺便说一下,您还应该为
req.GetResponse()
使用using
块。)您的内容类型是text/xml,但实际内容只是“dfwa”。这不是有效的XML文档
(顺便说一句,对于
req.GetResponse()
,您还应该使用using
块。)默认情况下,具有webHttpBinding/webHttp行为的端点接受XML或JSON格式的请求。您发送的XML需要符合服务的期望。下面的代码发送您的服务期望的请求。另外,请注意,您需要在HttpWebRequest上设置ContentType属性,而不是MediaType

请不要使用“ascienceoding.UTF8”-使用“Encoding.UTF8”。(ASCII和UTF8不是一回事。这段代码可以工作,但你真的不应该使用它。)请共享客户端和服务器的相关配置部分。我添加了服务器配置文件。除了im用于消费的项目的默认appconfig之外,没有其他内容请不要使用“ascienceoding.UTF8”-使用“Encoding.UTF8”。(ASCII和UTF8不是一回事。这段代码可以工作,但你真的不应该使用它。)请共享客户端和服务器的相关配置部分。我添加了服务器配置文件。除了我用来消费的项目的默认appconfig之外,没有其他内容更改为纯文本help@Tom:我猜web服务可能需要XML。。。或者可能形成编码数据。我怀疑你能否逃脱一个仅仅是输入参数值的实体
