Flutter Web Dio 无法进行简单的 POST

如何解决Flutter Web Dio 无法进行简单的 POST

任何帮助将不胜感激！如果不能解决Dio，建议Flutter Web 用什么其他的包做POST（我要能加followRedirect=false，这样基本的http 包就出来了）。谢谢！！

var resp = await Dio().post("xyz.com:1001/login",data: {"user": email,"pass" : pwd})

解决方法

您的网址缺少架构，例如：http://

所以尝试添加像 http://example.com/login

这样的方案
