Question

我正在开发部署在Azure App Service上的node.js应用程序。

应用程序在localhost上按预期运行 -

http://localhost:55231/search?q=pink+floyd

但是当部署在Azure上时，URL行为很奇怪 -

在查询字符串之前

http://<appname>.azurewebsites.net/search/?q=pink+floyd额外'/'。

我的Express.js代码是 -

app.get('/search', function (req, res) {
  response = {
  search_text:req.query.q,
  };
//Few more code

HTML页面提供查询 -

<form action = "/search" method = "GET">
  <input type = "text" name = "q" placeholder=" Search your Favourite Music">
  <input type = "submit" value = "Search">
</form>

我无法使用Express在Azure App Service上重现您的问题。但是，以下是我到目前为止所尝试的内容。

我的文件夹结构：

我的 app.js 代码如下：

var express = require('express')
var app = express()

app.use(express.static('public'))

app.get('/', function (req, res) {
  res.send('Hello Azure!')
})

app.get('/search', function(req, res) {
  res.send(200, 'Test')
})

app.listen(process.env.PORT || 3000, function () {
  console.log('Example app listening on port 3000!')
})

我的 test.html 代码：

<html>
  <head>
    <title>Test</title>
  </head>

  <body>
    <form action="search" method="GET">
      <input type="text" name="q" />
      <button type="submit">Search</button>
    </form>
  </body>
</html>

的web.config ：

<?xml version="1.0" encoding="utf-8"?>

               You can control how Node is hosted within IIS using the following options:
                 * watchedFiles: semi-colon separated list of files that will be watched for changes to restart the server
                 * node_env: will be propagated to node as NODE_ENV environment variable
                 * debuggingEnabled - controls whether the built-in debugger is enabled

               To debug your node.js application:
                 * set the debuggingEnabled option to "true"
                 * enable web sockets from the portal at https://manage.windowsazure.com/#Workspaces/WebsiteExtension/Website/aaronexpress/configure
                 * browse to https://aaronexpress.azurewebsites.net/app.js/debug/

测试结果：

你能分享你正在使用的 web.config 文件吗？我的猜测是你错过了一个简单的事情。

Azure App Service在URL中添加“/”
