前端跨域解决方案 上传者：困兽S 2020-01-02 21:14:30上传 ZIP文件 78.7KB 热度 71次 前端跨域解决方案，jsonp和cros两种解决方式。我们发现，Web页面上调用js文件时不受是否跨域的影响，凡是拥有"src"这个属性的标签都拥有跨域的能力，比如[removed]、、。那就是说如果要跨域访问数据，就服务端只能把数据放在js格式的文件里。恰巧我们知道JSON可以简洁的描述复杂数据，而且JSON还被js原生支持，所以在客户端几乎可以随心所欲的处理这种格式的数据。然后客户端就可以通过与调用脚本一模一样的方式，来调用跨域服务器上动态生成的js格式文件。客户端在对JSON文件调用成功之后，也就获得了自己所需的数据。这就形成了JSONP的基本概念。
