Question

当我尝试从开发服务器访问Web服务时，它会返回以下错误。当我从本地计算机访问相同的服务时，它工作正常。你知道可能是什么原因吗？非常感谢你提前！

405错误通常是由跨域问题引起的。如果您已部署服务，但正在localhost（或其他部署）上的客户端进行测试，则所有内容都不再在同一localhost域下运行，因此您需要启用跨域调用。

可以在此处找到启用跨域脚本编写的一个很好的示例： how to avoid cross domain policy in jquery ajax for consuming wcf service?

正如@Monkieboy所说，如果没有看到你的web.config文件就诊断起来有点困难，但是尝试通过添加crossDomainScriptAccessEnabled="true"来判断你正在使用哪种绑定，看看是否有帮助。
