**重点nginx跨域参考：[https://www.cnblogs.com/gaoyuechen/p/12880939.html][https_www.cnblogs.com_gaoyuechen_p_12880939.html]**

### **务必注意：add\_header Access-Control-Allow-Origin \*; 通配符配置所有的域名跨域在nginx会无效,多次测试依然如此，建议使用指定多域名跨域！** ###

### **【我跨域成功的配置】指定多域名配置跨域：** ###

#使用正则表达式配置多个域名跨域信息【nginx配置*全部域名跨域不安全,也不建议使用,其次本人配置全部跨域一直未成功,具体原因还未知...】
