推荐答案

该错误是由发送到服务器的自定义privatekey标头引起的.该字段必须包含在服务器的Access-Control-Allow-Headers响应标头中.可以使用:

The error is caused by the custom privatekey header that is send to the server. This field has to be included in the Access-Control-Allow-Headers response header from the server. It can be done using:

Access-Control-Allow-Headers: privatekey

使用php时，可以使用以下代码段:

when using php the following snippet can be used:

header('Access-Control-Allow-Headers: X-Requested-With, privatekey');
