使用AutoRest生成C# REST服务客户端时构造函数为internal且未添加凭据参数的问题排查

Let's break down your two problems and walk through solutions for each:

1. Internal Constructor Despite --public-clients=true #

The --public-clients=true parameter isn't taking effect likely due to one of these common issues:

• Parameter Spelling Mismatch: Newer versions of AutoRest's C# generator use the singular --public-client=true (not plural) to mark clients as public. Swap your plural parameter for the singular version in your command.
• Outdated Generator Version: Old AutoRest or C# generator packages can have parameter inconsistencies. Run autorest --version to check your current version, then update to the latest stable release with npm install -g autorest.
• OpenAPI Override: If your swagger.json includes extensions like x-ms-internal that force internal access, this will override the CLI parameter. Scan your OpenAPI document for such extensions and remove them if present.

2. Missing Credential Parameter in Constructor #

The --add-credential flag depends entirely on your OpenAPI document defining a valid security scheme—without this, AutoRest has no context to generate credential-aware constructors. Here's how to fix this:

• Add a Security Scheme to swagger.json: For example, if using Azure AD OAuth2, add this to the components section:

  "components": {
    "securitySchemes": {
      "azure_auth": {
        "type": "oauth2",
        "flows": {
          "authorizationCode": {
            "authorizationUrl": "https://login.microsoftonline.com/common/oauth2/v2.0/authorize",
            "tokenUrl": "https://login.microsoftonline.com/common/oauth2/v2.0/token",
            "scopes": {
              "https://management.azure.com/.default": "Default scope"
            }
          }
        }
      }
    }
  }
  

  Then apply this scheme globally by adding a root-level security section:

  "security": [
    {
      "azure_auth": []
    }
  ]
  

• Match Your Auth Type: If using API keys or another auth method, adjust the security scheme to match your setup. AutoRest will generate the correct credential constructor once it recognizes a valid security definition.

Revised Command to Test #

With the parameter fix and updated OpenAPI document, your command should look like this:

autorest --input-file="./Resources/swagger.json" --output-folder="./SomeService/Generated" --namespace="SomeService.Client" --override-client-name="SomeServiceClient" --skip-csproj --public-client=true --add-credential --csharp
