我正在尝试部署一个node.js应用程序,该应用程序为后台任务调用python脚本。我实现它的方式是通过python:
var pythonShell = require('python-shell');
var options = {
pythonPath: 've-env/bin/python3',
args:
[
req.query.term,
req.params.id,
req.session.user.searchName,
req.session.user.searchKey
]
};
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的路径是在options.pythonPath中指定的(在称为‘ve’的python虚拟环境中)。
这在我当地的环境中是可行的。但是,当我将我的应用程序部署到Azure app时,我收到了以下错误消息:
Error: spawn Unknown system error -8

在部署之前,我应该执行任何python环境配置吗?

答案是肯定的。如果要在Azure中运行python脚本,则需要在application.Please中安装python环境,请参阅以下步骤:
请参考我的工作步骤,看看是否还会出现错误。
步骤1:在门户上添加扩展(这里是Python3.6.1 x64)

步骤2:切换到Kudu并命令cd Python364x64和touch get-pip.py,并通过编辑按钮将url https://bootstrap.pypa.io/get-pip.py的内容复制到get-pip.py中,然后运行python get-pip.py来安装pip工具。

步骤3:通过python -m pip install requests安装所需的任何软件包

然后,您需要修改代码的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)希望它能帮到你。如果有任何问题,请告诉我。
