您好，我正在使用手机间隙技术进行黑莓开发。我想调用基于 soap 的 xml。当我在 Internet 上运行 html 页面时，探索 Web 服务响应会出现，但是当我在模拟器或设备中运行时，不会出现响应。请帮忙。提前谢谢。我使用了 java 脚本。

最佳答案
作为 WebWorks 应用程序，您需要将通过您的应用程序访问的任何外部域列入白名单。由于这适用于计算机的浏览器，但不适用于实际设备或模拟器，因此它可能是配置文件的问题。查看PhoneGap site有关白名单的更多信息。
关于javascript - 当我使用 javascript 调用 Web 服务时，在模拟器上没有得到响应，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11601322/
