Question

我正在尝试向我所做的本地服务器执行 http 请求，但我收到以下 I / flutter (28338) 错误消息：错误状态：平台不允许不安全的 HTTP： http://mylocalip/auth/login，有谁知道怎么解决吗？

注：我也在用模块化的flutter和mobx

I'm trying to make a request to a local http server, the request is a post for a login system that receives username and password by parameter

login() async {
try {
  var response = await http.post(http://mylocalip/auth/login,
      body: {'username': 'maximosdrr', 'password': '621251'});
  print(response.statusCode);
} catch (e) {
  print(e);
}
}

控制台输出如下：I / flutter (28338): Bad state: Insecure HTTP is not allowed by platform: http://mylocalip/auth/login

临时解决您的问题。首先在res/xml（我的完整路径是/Users/dolphin/source/third-party/Cruise/android/app/src/main/res/xml）文件夹中添加一个配置：

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true" />
</network-security-config>

然后在您的 AndroidManifest.xml 文件中添加此配置：

android:networkSecurityConfig="@xml/network_security_config"

这可能允许 http 流量。但它只是用来调试，最好的方法是使用 https 流量。更多信息：
