Flutter-macos构建目标上的http.get失败:连接失败

问题描述

我开始将Flutter应用程序移植到 macos Desktop .用户界面开始正常.但是，应用程序一旦进行网络通话，就会立即失败，并显示连接失败(操作系统错误:不允许操作).

I started porting my Flutter app to macos Desktop. The UI started fine. However, as soon as the app makes a network call, it fails instantly with Connection failed (OS Error: Operation not permitted).

运行单线:

final response = await http.get('https://jsonplaceholder.typicode.com/posts/1');

失败:

Unhandled Exception: SocketException: Connection failed (OS Error:
    Operation not permitted, errno = 1),
         address = jsonplaceholder.typicode.com, port = 443
#0      IOClient.send (package:http/src/io_client.dart:33:23)

macos构建目标来自Google的示例此处.

推荐答案

您的macOS XCode项目缺少Internet权限，称为传出连接(客户端)".

Your macOS XCode project lacks Internet permission called "Outgoing Connections (Client)".

打开您的macOS Xcode项目-[root]/macos/Runner.xcworkspace

Open your macos xcode project - [root]/macos/Runner.xcworkspace

在项目导航器中单击运行器"-将显示常规设置.从标签栏中选择功能"，然后勾选选项外向连接(客户端)" .

Click "Runner" in Project navigator - general settings will show up. Select "Capabilities" from tabbar and tick option "Outgoing Connections (Client)".

在XCode中重建应用程序并启动项目.

Rebuild your application inside XCode and launch the project.
