无法在 swagger ui 中处理 [GET] 响应

问题描述 投票：0回答：1

除了 GET 之外，所有 API 都可以无缝运行。我无法解决的问题请帮助我解决这个问题。

      /**
         * @swagger
         * /admin/get_all_languages:
         *   get:
         *     produces:
         *       - application/json
         *     summary: Get all languages.
         *     description:  This API fetches all the languages.
         *     tags:
         *       - Admin
         *     security:
         *       - JWTAuth: []  # Specify JWT as the authentication method
         *     responses:
         *       '200':
         *         description: Successful response - Fetched all languages successfully.
         *         content:
         *           application/json:
         *             schema:
         *               type: array  # Adjust this based on the actual response structure
         *       '401':
         *         description: Unauthorized. JWT token is missing or invalid.
         *       '500':
         *         description: Internal server error.
         */
        this.router.route('/get_all_languages').get(AuthService.authenticateToken, AdminController.getAllLanguages);

当我点击这个时，我收到此错误

错误：::1 HTTP/1.1 500 GET /api/v1/admin/get_role_for_assigning - 无法读取未定义的属性“lastIndexOf”（#unknown）： ServerError：无法读取未定义的属性“lastIndexOf” 在 Function.get (/home/cubix/vtt-backend/dist/api/core/factories/error.factory.js:31:28) 在工厂（/home/cubix/vtt-backend/dist/api/core/middlewares/catch.middleware.js:24:43） 在 Layer.handle_error (/home/cubix/vtt-backend/node_modules/express/lib/router/layer.js:71:5) 在trim_prefix（/home/cubix/vtt-backend/node_modules/express/lib/router/index.js:321:13） 在/home/cubix/vtt-backend/node_modules/express/lib/router/index.js:284:7 在 Function.process_params (/home/cubix/vtt-backend/node_modules/express/lib/router/index.js:341:12) 接下来（/home/cubix/vtt-backend/node_modules/express/lib/router/index.js:275:10） 在通知时（/home/cubix/vtt-backend/dist/api/core/middlewares/catch.middleware.js:21:9） 在 Layer.handle_error (/home/cubix/vtt-backend/node_modules/express/lib/router/layer.js:71:5) 在trim_prefix（/home/cubix/vtt-backend/node_modules/express/lib/router/index.js:321:13） 在/home/cubix/vtt-backend/node_modules/express/lib/router/index.js:284:7 在 Function.process_params (/home/cubix/vtt-backend/node_modules/express/lib/router/index.js:341:12) 接下来（/home/cubix/vtt-backend/node_modules/express/lib/router/index.js:275:10） 在 Layer.handle_error (/home/cubix/vtt-backend/node_modules/express/lib/router/layer.js:67:12) 在trim_prefix（/home/cubix/vtt-backend/node_modules/express/lib/router/index.js:321:13） 在/home/cubix/vtt-backend/node_modules/express/lib/router/index.js:284:7

这就是cors的处理方式

private options: Record<string, unknown> = {
    cors: {
      origin: (origin: string, callback: ( error: Error, status?: boolean ) => void) => {
        // origin = origin.trim(); // to remove extra space 
        console.log("Request Origin",origin)
        if (AUTHORIZED.indexOf(origin) !== -1) {
          // if (authorizedOrigins.includes(origin)) {
          callback(null, true);                                              
        } else {
          callback( notAcceptable('Domain not allowed by CORS') );
        }
      },
      methods: ['GET', 'POST', 'PUT', 'PATCH', 'DELETE'],
      allowedHeaders: ['Accept', 'Content-Type', 'Authorization', 'Origin', 'From'],
      credentials: true,
    },

Swagger 选项文件

const swaggerOptions = {
      definition: {
        openapi: '3.0.0',
        info: {
          title: 'Nitin API',
          version: '1.0.0',
          description: 'NITIN API Documentation'
        },
        servers: [
          {
              url: 'http://localhost:8101/api/v1',
              description: 'Local server'
          },
          {
              url: 'https://vtt.myclient.com/api/v1',
              description: 'DEV Env'
          }
        ],
        components: {
          securitySchemes: {
            JWTAuth: { // Define the Bearer Token (JWT) security scheme
              type: 'http',
              scheme: 'bearer',
              bearerFormat: 'JWT',
            }
          }
        },
        security: [{
          JWTAuth: []
        }]
      },
      apis: ['src/api/core/routes/v1/*.ts'],
      // apis: ['../core/routes/v1/*.ts']
    };

    const swaggerSpec = swaggerJsdoc(swaggerOptions);
    // console.log("swaggerSpec", swaggerSpec);
    const excludeSwagger = true;

    if(excludeSwagger){
      // this.application.use('/api-docs', (req, res, next) => {
      //   req.headers['Content-Type'] = CONTENT_TYPE_ENUM['application/json'];
      //   next();
      // });
      this.application.use('/api-docs', swaggerUi.serve, swaggerUi.setup(swaggerSpec));
    }

我可能会遇到此错误的部分

validate(req: Request, res: Response, next: (e?: Error) => void): void {

    if (req.method === 'OPTIONS') {
      res.writeHead(200, {
        'Access-Control-Allow-Origin': '*',
        'Access-Control-Allow-Headers': ['Content-Type', 'Authorization', 'Origin'],
        'Access-Control-Allow-Methods': '*',
      });
      res.end();
      return ;
    }

    if (!req.headers['content-type']) {
      return next( notAcceptable(`Content-Type headers must be ${CONTENT_TYPE} or 'multipart/form-data', ${req.headers['content-type']} given`) );
    }

    const contentType = req.headers['content-type'];

    if (['PATCH', 'POST', 'PUT'].includes(req.method)) {
      if(CONTENT_TYPE_ENUM['text/plain'] === req.headers['content-type']) {
        console.log('second')
        return next( notAcceptable(`Content-Type headers must be ${CONTENT_TYPE} or 'multipart/form-data', ${req.headers['content-type']} given`) );
      }
    }

    if ( CONTENT_TYPE_ENUM[CONTENT_TYPE] !== req.headers['content-type'] && req.headers['content-type'].lastIndexOf(CONTENT_TYPE_ENUM['multipart/form-data']) === -1 && CONTENT_TYPE_ENUM['text/plain'] !== req.headers['content-type'] && CONTENT_TYPE_ENUM['application/json; charset=utf-8'] !== req.headers['content-type']){
      console.log('third')
      console.log('req.headers', req.headers['content-type'])
      // if(req.headers['content-type'] === 'text/plain'){
      //   console.log('fourth')
      // }
      return next( notAcceptable(`Content-Type head must be ${CONTENT_TYPE}, multipart/form-data or application/json; charset=utf-8, but ${req.headers['content-type']} given`) );
    }

 if (!req.headers.origin) {
      return next( notAcceptable('Origin header must be specified') );
    }

我尝试删除标头，希望能够解决某些问题，但效果不佳，令人沮丧，也许我无法达到可能导致此问题的程度。

if(req.method === 'GET'){
      delete req.headers['content-type']
    }

    if (
      req.headers['content-type'] &&
      CONTENT_TYPE_ENUM[CONTENT_TYPE] !== req.headers['content-type'] &&
      req.headers['content-type'].lastIndexOf(CONTENT_TYPE_ENUM['multipart/form-data']) === -1 &&
      CONTENT_TYPE_ENUM['text/plain'] !== req.headers['content-type'] &&
      CONTENT_TYPE_ENUM['application/json; charset=utf-8'] !== req.headers['content-type']
    ) {
      console.log('third')
      console.log('req.headers', req.headers['content-type'])
      return next( notAcceptable(`Content-Type head must be ${CONTENT_TYPE}, multipart/form-data or application/json; charset=utf-8, but ${req.headers['content-type']} given`) );
    }

如果我做了一些愚蠢的事情，请忽略任何帮助，我们将不胜感激。 谢谢！

您似乎陷入了 GET 请求，您正在尝试删除标头，但这无济于事，而是尝试查找请求方法 GET 并设置一个条件来检查标头是否未接收内容类型应用程序 json 然后进行分配

req.headers['content-type'] = 'application/json';

这应该可以解决您的错误。
