chrome中出错:Access-Control-Allow-Headers不允许使用Content-Type

Question

我在尝试发送ajax请求时在Chrome中收到此错误:

Content-Type is not allowed by Access-Control-Allow-Headers

在Firefox中一切正常.

任何人都可以帮我解决这个问题吗？

Answer 1

我解决了向Apache Web Server虚拟主机配置添加以下设置的问题

Header set Access-Control-Allow-Origin "*"
Header set Access-Control-Allow-Headers "Origin, X-Requested-With, Content-Type, Accept"

Answer 2

PHP解决方案:

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: POST,GET,OPTIONS');
header('Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept');

(需要在任何其他内容之前发送)

Answer 3

在node.js中设置CORS（跨站点HTTP请求）。对我来说，它看起来像下面这样：

app.use('/api', function(req, res, next) {
  res.header('Access-Control-Allow-Origin', '*');
  res.header('Access-Control-Allow-Headers', 'X-Requested-With, Content-Type');
  next();
});
