所以我在玩Expo+Rreact Native+yoga graphql服务器+Apollo客户端，通过查询获取数据可以在浏览器中工作，当我在Expo中点击"在浏览器中运行"时，但如果我试图在android模拟器上运行应用程序，就会引发网络错误/qr代码。附言：我在github上读到了类似的帖子和问题，所以我设法通过nat和无ip从"外部"访问了我的graphql端点。(所以这不是本地主机的问题)。这是控制台中抛出的错误。log(错误)：

我做错了什么？：-(
所以，如果你想让你的graphql端点从"外部世界"访问，你必须在https下进行，因为expo服务器运行在一个安全的连接上，它会拒绝从一个不安全的连接加载数据。我一直在尝试在graphql yoga服务器上实现ssl，但最终将graphql端点部署到heroku或prisma云会更快，因为那里提供了开箱即用的https！不过，我上面显示的堆栈错误与Apollo没有获取数据无关，因为即使现在它仍然会弹出！我希望这能帮助其他人腾出一些时间！
