Swagger规范中定义的Swagger路由，但没有定义get操作。

Question

我正在使用swagger创建一个nodejs web服务。于是，我使用了swagger的在线编辑器，完成了我的yaml，并将其导出到nodejs服务器。当我在我的计算机上运行时，主机作为本地主机(参见yaml)，我尝试执行一个PUT --我得到了这样的消息：

Error: Route defined in Swagger specification (/test) but there is no defined get operation.

和

我有一个get操作，所以我不知道是什么错误。以下是我的主要文件：

definitions: ........ 

index.js:

'use strict';

    var fs = require('fs'),
        path = require('path'),
        http = require('http')

    var app = require('connect')();
    var swaggerTools = require('swagger-tools');
    var jsyaml = require('js-yaml');
    var serverPort = 8080;

    // swaggerRouter configuration
    var options = {
      swaggerUi: path.join(__dirname, '/swagger.json'),
      controllers: path.join(__dirname, './controllers'),
      useStubs: process.env.NODE_ENV === 'development' // Conditionally turn on stubs (mock mode)
    };

    // The Swagger document (require it, build it programmatically, fetch it from a URL, ...)
    var spec = fs.readFileSync(path.join(__dirname,'api/swagger.yaml'), 'utf8');
    var swaggerDoc = jsyaml.safeLoad(spec);

    // Initialize the Swagger middleware
    swaggerTools.initializeMiddleware(swaggerDoc, function (middleware) {
      // Interpret Swagger resources and attach metadata to request - must be first in swagger-tools middleware chain
      app.use(middleware.swaggerMetadata());

      // Validate Swagger requests
      app.use(middleware.swaggerValidator());

      // Route validated requests to appropriate controller
      app.use(middleware.swaggerRouter(options));

      // Serve the Swagger documents and Swagger UI
      app.use(middleware.swaggerUi());

      // Start the server
      http.createServer(app).listen(serverPort, function () {
        console.log('Your server is listening on port %d (http://localhost:%d)', serverPort, serverPort);
        console.log('Swagger-ui is available on http://localhost:%d/docs', serverPort);
      });

    });

和my控制器:

'use strict';

var url = require('url');

var test = require('./testService');

module.exports.addTestConf = function addTestConf(req, res, next) {
  test.addTestConf(req.swagger.params, res, next);
};

module.exports.getTestConfigurationById = function getTestConfigurationById(req, res, next) {
  test.getTestConfigurationById(req.swagger.params, res, next);
};

test_configurationService.js:

use strict';

exports.addTestConf = function(args, res, next) {
  res.end();
}

exports.getTestConfigurationById = function(args, res, next) {
  res.end();
}

Answer 1

operationId必须与控制器函数匹配。

看起来，您的代码中存在一种情况不匹配：

• operationId: addTestconf
• 功能名称: addTestConf

Answer 2

这是与CORS相关的问题。

如果尝试使用与.yaml文件中指示的不同的url/主机请求Api，则会得到以下错误

所以如果在你的.yaml里

host: "localhost:8085"

并使用127.0.0.1:8080，您可能会面临这个问题。
