运行.NET Aspire启动应用时遇applicationUrl配置错误求助

错误信息： #

One or more errors occurred. (The 'applicationUrl' setting must be an https address unless the 'ASPIRE_ALLOW_UNSECURED_TRANSPORT' environment variable is set to true. This configuration is commonly set in the launch profile.)

两种解决办法： #

1. 将applicationUrl改为HTTPS地址

找到项目下Properties/launchSettings.json文件，修改对应启动配置里的applicationUrl字段，确保包含HTTPS地址。示例：

"profiles": {
  "YourAppName": {
    "commandName": "Project",
    "dotnetRunMessages": true,
    "launchBrowser": true,
    "applicationUrl": "https://localhost:5001;http://localhost:5000",
    "environmentVariables": {
      "ASPNETCORE_ENVIRONMENT": "Development"
    }
  }
}

如果不需要HTTP地址，直接只保留HTTPS地址即可。

2. 设置ASPIRE_ALLOW_UNSECURED_TRANSPORT环境变量为true

• 临时设置（当前终端生效）：
  • Windows命令行：

    set ASPIRE_ALLOW_UNSECURED_TRANSPORT=true
    

  • PowerShell：

    $Env:ASPIRE_ALLOW_UNSECURED_TRANSPORT = "true"
    

• 持久化到启动配置：
  在launchSettings.json的对应启动配置里，添加环境变量：

  "profiles": {
    "YourAppName": {
      // 其他配置...
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development",
        "ASPIRE_ALLOW_UNSECURED_TRANSPORT": "true"
      }
    }
  }
