flutter——实现支付宝支付tobias

需求：支付宝支付

使用tobias：https://github.com/OpenFlutter/tobias/blob/master/README_CN.md

1、在yaml里

tobias:
  url_scheme: tobiasexample
  ios:
    ignore_security: true

2、info plist里。好像会自动生成

   
      CFBundleTypeRole
      Editor
      CFBundleURLName
      alipay
      CFBundleURLSchemes
      
         tobiasexample
      
   

3、在xcode里的info 的url types

设置好，要和2上面的参数一一对应

4、页面代码：

class PayRequest{
  // 支付宝支付，返回一个对象
  static Future aliPay(String itemName) async{
    final url = "alipay-app-pay/";
    final res = await HttpRequest.request(url,method: "post",
        params: {"item_name":itemName});
    // 解决'_Map' is not a subtype of type 'FutureOr'的报错
    final Map jsonData = res;
    final AliPayEntity aliPayEntity = AliPayEntity.fromJson(jsonData);
    return aliPayEntity;
  }
}
Tobias tobias = Tobias();
// 支付宝支付
Future aliPay() async{
  // 先写死
  String itemName = "600钻石";
  AliPayEntity aliPayEntity = await PayRequest.aliPay(itemName);
  print("支付宝支付，后端返回的${aliPayEntity.orderStr}");
  tobias.pay(aliPayEntity.orderStr);
}
