javascript - 将数据从 Node 发送到python并打印

Question

我一直在尝试在 Node 和python之间进行通信我想将对象数组发送到 python，并在 python 中打印它，但我的代码无法正常工作。

content=[
{

    "username": "admin",
    "first_name": "",
    "last_name": "",
    "roles": "system_admin system_user",
    "locale": "en",
    "delete_at": 0,
    "update_at": 1511335509393,
    "create_at": 1511335500662,
    "auth_service": "",
    "email": "adminuser@cognizant.com",
    "auth_data": "",
    "position": "",
    "nickname": "",
    "id": "pbjds5wmsp8cxr993nmc6ozodh"
},
{

    "username": "chatops",
    "first_name": "",
    "last_name": "",
    "roles": "system_user",
    "locale": "en",
    "delete_at": 0,
    "update_at": 1511335743479,
    "create_at": 1511335743393,
    "auth_service": "",
    "email": "chatops@cognizant.com",
    "auth_data": "",
    "position": "",
    "nickname": "",
    "id": "akxdddp5p7fjirxq7whhntq1nr"
}]

JavaScript 代码:

const express=require('express')

const app=express()

let p = require('python-shell');

app.get('/send',(req,res)=>{


    var options = {
        args:
        [
          content

        ]
      }
      p.PythonShell.run('hello.py', options, function  (err, results)  {


        console.log(results.toString())

      });

})

app.listen('5000')

Python 脚本:

import sys 

import json

details=sys.argv[1]

print (details)

由于我们无法将对象传递给命令行，python-shell 正在调用内容对象上的 .toString() 方法。使其成为对象对象。

解决方案:将您的 options 对象更改为:

var options = {
        args:
        [
          JSON.stringify(content)

        ]
      }

在 python 文件中:

parsed = json.loads(sys.argv[1])
print (json.dumps(parsed))
