Question

我尝试从浏览器访问我开发的简单邮件列表服务。我修改了一个我找到的工作示例，但我不知道为什么请求似乎没有到达服务，因此没有返回任何响应。

使用SOAP信封是一项要求，我需要知道这段代码可能出现的问题，而不是我如何使用其他技术做同样的事情。（该服务在GlassFish服务器上正确部署，我有一个可用的Java客户端来测试它，所以服务没问题）

有没有人看到不好的东西（我也加入了WSDL，如果你需要任何其他细节，请不要犹豫）？谢谢！

当我尝试在Firefox上执行时，我在错误控制台中没有出现任何错误，而Internet Explorer只显示Loading...而已。

Answer 1

SOAP必须通过POST发送，而不是GET。

此外，您的WS-Messaging标头看起来是错误的。事实上，我甚至都看不到它们。

尝试使用.NET客户端发出此调用（“添加服务引用”），并使用Fiddler或类似的内容查看电话，看看发生了什么。然后做同样的事情。

使用带有SOAP信封的Javascript调用Web服务失败
