但是当我尝试颤动时,请求从不响应:
getCategories() async {
String url = 'http://localhost:4444/categorie?page_size=15&page=1';
var response = await http.get(url);
if (response.statusCode == 200) {
// If the call to the server was successful, parse the JSON
return response.body;
} else {
// If that call was not successful, throw an error.
throw Exception('Failed to load post');
}
}

我跑我的服务器Windows10使用Django。我的颤振应用程序正在Android Studio使用Virtual Machine作为设备。我尝试将 ip 更改为127.0.0.1,10.0.0.1但仍然无法正常工作。我是否更改了 Django 的主机或在我的颤振中或内部启用了任何配置VirutalBox?

您 PC 上的本地主机与 Android 模拟器上的不同。要从 Android 模拟器访问 PC 的本地主机,您需要指向10.0.2.2.
这意味着您需要将代码更改为:
String url = 'http://10.0.2.2:4444/categorie?page_size=15&page=1';
