var pythonShell = require('python-shell');

pythonShell.run('VideoAnalyzer/Search.py', options, function (err, data) {
if (err)
throw err ;
var values = JSON.parse(data[0]).value;
var resultsByRel = values;
res.render('video', {resultsByRel: resultsByRel, resultsByTime: [], searchTerm: req.query.term, url: req.query.url});
});
python的路径在options.pythonPath(在名为“ve env”的python虚拟环境中)中指定
这在我当地的环境中起作用。但是,当我将我的应用程序部署到Azure应用程序服务时,我收到以下错误消息:
Error: spawn Unknown system error -8

该应用程序部署在Linux环境中,节点版本为v8.9
在部署之前,我是否应该执行任何python环境配置
是否有我应该执行的python环境配置
部署前
答案是肯定的。如果要在Azure App Service中运行python脚本,需要在应用程序中安装python环境。请参阅以下步骤:
请参考我的工作步骤,看看错误是否仍然出现
步骤1:在门户上添加扩展(这里是Python 3.6.1 x64)
步骤2:切换到Kudu CMD并使用命令cd Python364x64
和触摸get pip.py
并复制url的内容https://bootstrap.pypa.io/get-pip.py
通过编辑按钮进入get pip.py
,然后运行python get pip.py
安装pip工具
步骤3:通过python-mpip安装请求安装您需要的任何软件包
然后需要修改代码的python配置:
var express = require('express');
var pythonShell = require('python-shell');
var router = express.Router();
var options = {
pythonPath: 'D:/home/python364x64/python',
scriptPath: 'D:/home/site/wwwroot'
// args:
// [
// req.query.term,
// req.params.id,
// req.session.user.searchName,
// req.session.user.searchKey
// ]
};
var resultsByRel;
pythonShell.run('TestRequests.py', options, function (err, data) {
if (err) throw err;
// results is an array consisting of messages collected during execution
var values = JSON.parse(data[0]);
resultsByRel = values;
console.log('results: %j', resultsByRel);
});
router.get('/', function(req, res, next) {
res.send(resultsByRel);
// res.render('executePython', resultsByRel );
});
module.exports = router;
我的简单python脚本:
import requests
r= requests.get("https://www.bing.com")
print (r.status_code)
