在Azure Functions上部署Node应用 [英] Deploying a Node app on Azure Functions

问题描述

我想知道如何在Azure Functions上部署Node.js应用程序.

I am wondering about how it might be possible to deploy a Node.js app on Azure Functions.

基本上，我有一个功能设置并运行一个基本的hello world http示例，如下所示:

Basically, I have a function setup and running a basic hello world http example that looks like:

module.exports = function (context, req) {
    context.log('JavaScript HTTP trigger function processed a request.');
    context.res = {
        // status: 200, /* Defaults to 200 */
        body: "Hello " + req.params.name
    };
    context.done();
};

我要部署到功能中的应用程序是一个使用swagger的简单moc客户端(基本上接受请求并返回一些xml). app.js看起来像:

The app I am trying to deploy into a function is a simple moc client that uses swagger (basically takes a request and returns some xml). The app.js looks like:

const SwaggerExpress = require('swagger-express-mw');
const app = require('express')();
const compression = require('compression');

const configSwagger = {
    appRoot: __dirname, // required config
};


SwaggerExpress.create(configSwagger, (err, swaggerExpress) => {
    if (err) {
        throw err;
    }

    // install middleware
    swaggerExpress.register(app);

    // server configuration
    const serverPort = process.env.PORT || 3001;
    app.listen(serverPort, () => {
        //logger.info('Listening on port %s', serverPort);
    });

    app.use(compression());
});

module.exports = app; // for testing

我不确定的是当使用modeul.exports建立函数时(即module.exports = function(context，req))如何处理module.exports = app

The thing I am not sure about is how to handle module.exports = app when modeul.exports is used to establish the function (i.e. module.exports = function (context, req))

推荐答案

您可以尝试使用

You can try to use azure-function-express to enable your swagger middleware.

请注意，某些中间件将无法正常运行(例如，body-parser).这是因为函数req不是流-它被注入到具有已填充的'body'属性的函数中.

Note that certain middleware will not function correctly (for example, body-parser). This is because the functions req is not a stream - it is injected into the function with a 'body' property already populated.
