Javascript Safari因“访问控制允许标头不允许请求标头字段内容类型”而导致XMLHttpRequest（POST）失败
我只是尝试使用httpbin测试XMLHttpRequestsJavascript Safari因“访问控制允许标头不允许请求标头字段内容类型”而导致XMLHttpRequest（POST）失败,javascript,ajax,safari,Javascript,Ajax,Safari,我只是尝试使用httpbin测试XMLHttpRequests <!DOCTYPE html> <html> <head lang="en"> <meta charset="UTF-8"> <title></title> </head> <body> <script type="text/javascript"> (function() { var

编辑：抱歉，我想我的主要问题是1如何解决此问题，以便safari上的POST请求不会引发错误出于安全原因，一些浏览器会检查主机和访问控制允许源是否相同，或者访问控制允许源是否允许主机url发出该请求，这样你的浏览器就可以保护你免受chrome浏览器的攻击，你可以禁用该安全功能 甚至还有一种解释
