Question

休息Wcf Serivce接受图片上传。它接受图像为base64string。我创建了一个简单的aspx页面来上传图像。但是我遇到了很多错误。 “有时香奈儿工厂不可用” “没有端点监听”的错误。这是我的web.config文件。我不明白我在做什么错。任何帮助将不胜感激。目前，服务和客户端位于我的本地系统上。

客户端和服务器端点配置不匹配。在服务上，您有一个带有“webHttpBinding”的端点和一个包含<webHttp/>行为的行为配置。在客户端上，您有一个自定义绑定，它不等同于webHttpBinding，并且没有行为。

问题似乎是REST端点不公开元数据，因此“添加服务引用”对它们不起作用。尝试将合同和绑定配置复制到客户端，或者如果它只是一个简单的“上传”服务，您可以使用比WCF更简单的东西，例如WebClient类。
