远程服务器返回意外响应:(400) 错误请求 WCF REST

Question

我找到了类似的帖子，但我尝试过的所有内容都不起作用。你能告诉我我做错了什么吗？首先是我的客户端配置，其次是我的服务器配置。首先，我认为这是因为我尝试接收大量数据，但这不是我的问题。

出的一件事是客户端配置中的<client>配置，特别是地址属性。

address="http://localhost:56923/TestService.svc?wsdl"

首先，你说你正在使用 REST，所以 WSDL 文件在其中没有发挥作用（它用于 SOAP 服务）。

其次，WSDL 文件不是服务，它是 Web Service Description Language 文件，它描述了 Web 服务，以便客户端可以为它构建代理（同样，这是针对 SOAP，而不是 REST）。

尝试将客户端配置中的地址更改为仅服务文件：

address="http://localhost:56923/TestService.svc"
