我正在尝试访问网页内容，作为我正在创建的 javascript Chrome 扩展功能的一部分，但遇到了一些难题。
在我的扩展程序脚本中作为 Ajax GET 请求的一部分访问资源时，资源无法正确加载。当我通过 hurl.it 尝试相同的 GET 请求时(打开跟随重定向并且没有 header 修改)，数据加载。如果我只在浏览器中输入 URL，它也可以工作。
我无法弄清楚 hurl.it 在其请求中做了什么不同的事情以及如何修复我自己的请求。
我尝试查询的 URL 格式为(以“Hello”作为搜索示例):
这将出现在我的脚本中，如下所示:
var get_url = "http://overdrive.dclibrary.org/BANGSearch.dll?Type=FullText&PerPage=24&URL=SearchResults.htm&Sort=SortBy%3DRelevancy&FullTextField=All&FullTextCriteria=Hello&x=0&y=0"
$.get(get_url,function(data){
console.log(data);
});
需要明确的是，上面的代码将将 HTML 输出到控制台。它只是不包含搜索查询的任何结果。
提前致谢!
编辑:我的扩展已被授予访问 dclibrary.org 域中任何内容的权限。
最佳答案
响应中存在重定向，这可能会破坏浏览器。 HTTP/1.1 302 Moved 暂时可以在 Chrome 中使用。为什么它返回 302 响应？使用 ASP.net/IIS，有时未经授权(未登录)的用户会通过 302 响应进行重定向。这是不好的行为，如果需要登录，它应该发出 403，但显然这不是意图。
使用 Fiddler 调试完整 header (或 chrome 开发工具)。
