一、发现问题
1、Android手机可以正常显示所有小程序页面
①页面中----第三方服务器链接的页面http导图可以正常显示
② 页面中----wx.request第三方服务器的https数据可以正常提取
2、ios手机不能显示小程序所有页面
①页面中----第三方服务器链接的http导图可以正常显示
②页面中----wx.request第三方服务器的https数据无法提取
二、分析问题
1、由于微信小程序的第三方服务器链接的图片都可以正常显示
2、明确问题，应该是ios在wx.request对接中受到限制
三、明确问题
判断是SSL证书有问题，但证书状态完全正常，小程序后台的安全域名也添加的没问题，最后解决办法是：换了一家SSL证书，并重启Nginx
四、重启nginx
