【问题描述】:
我尝试从浏览器访问我开发的一个简单的邮件列表服务。我改编了我找到的一个工作示例,但我不知道为什么请求似乎没有到达服务,因此没有返回响应。
使用 SOAP 信封是一项要求,我需要知道这段代码可能有什么问题,而不是如何使用其他技术来做同样的事情。 (该服务已正确部署在 GlassFish 服务器上,并且我有一个可以工作的 Java 客户端对其进行测试,因此该服务没有问题)
有没有人看到不好的东西(我也加入了 WSDL,如果您需要任何其他细节,请不要犹豫)?谢谢!

当我尝试在 Firefox 上执行错误控制台时,我没有收到任何错误,而 Internet Explorer 仅显示 Loading...,仅此而已。
【问题讨论】:
-
纯 Javascript 没有框架? AJAX 是一种痛苦......
-
是的纯 Javascript。我找到了一个运行良好的示例,唯一的区别是它发出了
POST请求。
