怎么实现跨域创建和写文件
如何实现跨域创建和写文件
假设有两个域名指向我的服务器，分别是
a.com指向../a/.. b.com指向../b/..
如果我在a.com里要创建和修改b.com里面的文件。。
有什么办法可以实现的，是不是一定要在b.com里才能操作？
------解决方案--------------------
有很多种，如果两个域名路径在同一个服务器上，那么你只需要对路径进行操作即可，例如../a/a.php操作../b/b.txt，那么路径就是../b/b.txt就行了
也可以用代理，例如你b.com文件请求a.com中的文件，那么你可以在b.com中想a.com中一个php文件发送请求，然后a.com中的php文件再操作a.com下的文件
当然了也可以直接通过url操作文件，不过要注意一些问题
------解决方案--------------------
不同服务器的话让b开放接口.
相同服务器直接去修改磁盘文件.
