第 5 章 ActiveDocs 和 OAuth

ActiveDocs 允许用户从一个位置测试和调用启用了 OAuth 的 API。

先决条件

5.1. 3scale 规格中的客户端凭证和资源所有者流示例

第一个示例是在 3scale 规格中使用 OAuth 2.0 客户端凭证流的 API。此 API 接受任何路径并返回有关请求的信息(path、请求标头、标头等)。Echo API 只能通过有效的访问令牌访问。API 的用户只能在为访问令牌交换其凭据(client_idclient_secret)进行调用。

若要让用户能够从 ActiveDocs 调用 API,用户必须请求访问令牌。由于这仅仅是对 OAuth 授权服务器的调用,您可以为 OAuth 令牌端点创建 ActiveDocs 规格。这允许从 ActiveDocs 中调用此端点。在这种情况下,对于客户端凭证流,Swagger JSON 规格如下:

{
  "swagger": "2.0",
  "info": {
    "version": "v1",
    "title": "OAuth for Echo API",
    "description": "OAuth2.0 Client Credentails Flow for authentication of our Echo API.",
    "contact": {
      "name": "API Support",
      "url": "http://www.swagger.io/support",
      "email": "support@swagger.io"
    }
  },
  "host": "red-hat-sso-instance.example.com",
  "basePath": "/auth/realms/realm-example/protocol/openid-connect",
  "schemes": [
    "http"
  ],
  "paths": {
    "/token": {
      "post": {
        "description": "This operation returns the access token for the API. You must call this before calling any other endpoints.",
        "operationId": "oauth",
        "parameters": [
          {
            "name": "client_id",
            "description": "Your client id",
            "type": "string",
            "in": "query",
            "required": true
          },
          {
            "name": "client_secret",
            "description": "Your client secret",
            "type": "string",
            "in": "query",
            "required": true
          },
          {
            "name": "grant_type",
            "description": "OAuth2 Grant Type",
            "type": "string",
            "default": "client_credentials",
            "required": true,
            "in": "query",
            "enum": [
                "client_credentials",
                "authorization_code",
                "refresh_token",
                "password"
            ]
          }
        ]
      }
    }
  }
}

对于资源所有者 OAuth 流,请为用户名和密码添加参数,以及提供访问令牌所需的其他参数。对于这个客户端凭证流,您要发送 client_idclient_secret,这可从对签名用户的 3scale 值填充,以及 grant_type。

然后,在 Echo API 的 ActiveDocs 规格中,添加 access_token 参数,而不是 client_idclient_secret

{
  "swagger": "2.0",
  "info": {
    "version": "v1",
    "title": "Echo API",
    "description": "A simple API that accepts any path and returns information about the request",
    "contact": {
      "name": "API Support",
      "url": "http://www.swagger.io/support",
      "email": "support@swagger.io"
    }
  },
  "host": "echo-api.3scale.net",
  "basePath": "/v1/words",
  "schemes": [
    "http"
  ],
  "produces": [
    "application/json"
  ],
  "paths": {
    "/{word}.json": {
      "get": {
        "description": "This operation returns information about the request (path, request parameters, headers, etc.),
        "operationId": "wordsGet",
        "summary": "Returns the path of a given word",
        "parameters": [
          {
            "name": "word",
            "description": "The word related to the path",
            "type": "string",
            "in": "path",
            "required": true
          },
          {
            "name": "access_token",
            "description": "Your access token",
            "type": "string",
            "in": "query",
            "required": true
          }
        ]
      }
    }
  }
}

然后您可以在 Developer Portal 中包含 ActiveDocs。在这种情况下,由于您想要指定它们显示具有 OAuth 端点的顺序,因此类似如下:

{% active_docs version: "2.0" services: "oauth" %}





<script type="text/javascript">
  $(function () {
    window.swaggerUi.load(); // <-- loads first swagger-ui

    // do second swagger-ui

    var url = "/swagger/spec/echo-api.json";
    window.anotherSwaggerUi = new SwaggerUi({
      url: url,
      dom_id: "another-swagger-ui-container",
      supportedSubmitMethods: ['get', 'post', 'put', 'delete', 'patch'],
      onComplete: function(swaggerApi, swaggerUi) {
        $('#another-swagger-ui-container pre code').each(function(i, e) {hljs.highlightBlock(e)});
      },
      onFailure: function(data) {
        log("Unable to Load Echo-API-SwaggerUI");
      },
      docExpansion: "list",
      transport: function(httpClient, obj) {
        log("[swagger-ui]>>> custom transport.");
        return ApiDocsProxy.execute(httpClient, obj);
      }
    });

    window.anotherSwaggerUi.load();

  });
</script>
