safari 下cookie bug

safari 的设cookie值，不要以，结尾：document.cookie = "server_site_str_init=2345;path=/;domain=.12345.com";
document.cookie = "server_site_str=111;path=/;domain=.12345.com";
//document.cookie = "server_site_str=htrecom3333mend,;path=/;domain=.12345.com";document.cookie = "server_site_str_init=2345;path=/;domain=.12345.com";
document.cookie = "server_site_str=111;path=/;domain=.12345.com";
document.cookie = "server_site_str=htrecom3333mend,;path=/;domain=.12345.com";
最后一个值有了逗号，请求到子域下的接口，cookie没有带过去
