我创建了一个 WCF Web 服务。该服务有一个名为“login”的 post 方法,它接受一个 json 对象作为输入,并返回一个 json 对象作为输出。当我在 localhost 中调用此方法时,它工作正常。但是当我发布它并调用此方法时,出现内容类型错误。我有一个网络服务库和一个网络服务站点。Web 服务站点除了调用服务库之外什么都不做。请在下面查看我的代码

我的测试结果:

在测试 localhost url 时:

http://localhost:15021/Service1.svc/json/login

(输入参数提供给我: {"UserID":"R","Password":"r"} )

返回: {"Created_at":null,"ID":"79","Message":"Successful","Name":"R","Status":0,"Updated_at":null}

在测试发布的 URL 时:

http://nsittest.nsit.com.au/ServiceSide/service.svc/json/login (输入参数提供给我:{"UserID":"R","Password":"r"})

返回: 抛出异常:远程服务器返回错误:(415)无法处理消息,因为内容类型'application/x-www-form-urlencoded'不是预期的类型'application/soap+xml; 字符集=utf-8'..

您可以看到该服务已启动并正在运行。我什至可以调用使用 get 方法的 getData 方法:

提前致谢。我试图从最近几天解决这个问题。我经历了很多形式,但无法解决。

请帮忙....

WCF 期待 SOAP 1.2 请求,该请求应包含content-type = application/soap+xml; charset=utf-8在其 HTTP 标头中。您的客户指定错误content-type = application/x-www-form-urlencoded。问题出在客户端,而不是服务器。

必须将方法参数更改为登录(JSON 值)。那成功了。
