这是哪里报的错误

authorize执行完没有根据路径调用 access_token 后台没有报错,return wxLogin("weixin").authorize(redirect_uri, "snsapi_base", "2019");
通过微信调试工具 报这个 XMLHttpRequest cannot load https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx6a7b19b0fbd21040&redirect_uri=https%3A%2F%2F24736g26e1.zicp.vip%2Falfx%2Fwx%2Fweixin%2Faccess_token&response_type=code&scope=snsapi_base&state=2019#wechat_redirect. Response for preflight is invalid (redirect)

我把路径拷贝出来在微信web测试端执行正常,不知道哪里出了问题!

@Ok(">>:${obj}") 应该是这个重定向执行报的错误

这样写试试

@Ok("void")


String url = wxLogin("weixin").authorize(redirect_uri, "snsapi_base", "2019")';
log.info(url);
resp.sendRedirect(url);

还是不行

这是打印出来的url

https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx6a7b19b0fbd21040&redirect_uri=https%3A%2F%2F24736g26e1.zicp.vip%2Falfx%2Fwx%2Fweixin%2Faccess_token&response_type=code&scope=snsapi_base&state=vii1s95ki4j3pq14ccbf4spgf0#wechat_redirect

下面是微信调试工具显示的信息

不能ajax啊,微信登录要跳转的,ajax不行

话说,你这是做微信公众号登录呢?还是微信网页登录?

当前你的代码是网页登录

微信公众号登录 哈哈,应该是ajax的原因,改一下

公众号走的是jssdk哦

我给的例子是网页登录,误导你了
