Windows phone 7 WP7和WP8中httpwebresponse的WebBrowser控件中的加载问题
我试图通过将httpwebresponse中的html代码存储在字符串变量中来加载web浏览器 我通过在其中设置cookies并在httpwebResponse中获取html页面，为URL创建了httpwebrequest 我试图通过将代码保存在字符串变量中，将其显示在web浏览器控件中。以及浏览browserbrowse.NavigateToStringstring 但这里的页面没有正确加载，它没有显示任何css或图像，也没有显示一条消息，您需要打开java脚本才能显示内容 在导航之前，我将web浏览器属性IsScriptEnabled设置为true。但它仍然显示消息和内容未正确加载 Cookie也不会被注入到web浏览器控件中。应用程序不会在整个应用程序中维护会话 是否有任何解决方案或解决方法 请参阅以下代码： 要从登录服务记录Cookie，请执行以下操作： 私人无效后登录请求 {Windows phone 7 WP7和WP8中httpwebresponse的WebBrowser控件中的加载问题,windows-phone-7,windows-phone-8,httpwebrequest,webbrowser-control,httpwebresponse,Windows Phone 7,Windows Phone 8,Httpwebrequest,Webbrowser Control,Httpwebresponse,我试图通过将httpwebresponse中的html代码存储在字符串变量中来加载web浏览器 我通过在其中设置cookies并在httpwebResponse中获取html页面，为URL创建了httpwebrequest 我试图通过将代码保存在字符串变量中，将其显示在web浏览器控件中。以及浏览browserbrowse.NavigateToStringstring 但这里的页面没有正确加载，它没有显示任何css或图像，也没有显示一条消息，您需要打开java脚本才能显示内容 在导航之前，我将w

当您导航到站点并保存文档时，您不会得到脚本、css或图像文件以及任何其他资源，而只会得到静态/生成的HTML文档，它们可能使用相对路径引用这些文件。如果路径不是绝对路径，则找不到脚本/css/图像/其他资源 如果要使其正常工作，需要将HTML文件中的相对路径替换为绝对路径 所以如果你有 你会用
请注意，这只是我的最佳猜测，而不是我实际尝试过的：您确定从WebResponse接收到的html内容是正确的吗？只是好奇…尝试将响应保存在记事本文件中，将扩展名设置为.html并尝试在IE desktop中打开。这很奇怪。我正在使用WP7.x/WP8.x从例如下载动态内容.EA网站大量使用javascript和JSON内容，一切正常。也许你可以在这里复制/粘贴一些核心代码？@Abhishek..如何测试web响应中的html内容是否正确？？？@Mikki Viitala请参考下面的代码示例。我面临的主要问题是我需要在hybri中维护一个会话d应用程序。一旦用户登录应用程序。我正在尝试保存cookies并将cookies注入web浏览器以供进一步请求，以便用户登录到会话结束。我保存了html代码并在IE桌面中打开。它显示的页面与windows phone web浏览器中的页面相同，没有图像css。
