python - 如何在从烧瓶到客户端的请求中发送多个命令？

问题描述

我刚刚开始使用烧瓶并设置了烧瓶服务器。这个想法是用户将看到一个基于 Web 的 UI，通过它输入一些参数并点击运行按钮。然后将参数传递给服务器，服务器应在用户系统上打开命令提示符并执行以下操作：-

  1. 推送路径
  2. 使用用户通过 UI python script.py -a arg1 -a arg2 提供的参数运行位于路径中的脚本（仅作为示例）

烧瓶服务器

from flask import Flask, render_template, request
import subprocess
app = Flask(__name__)

@app.route("/")
def home():
    return render_template("home.html")

@app.route("/person", methods =['POST','GET'])
def person():
    if request.method == 'POST':
        data = request.form
        return subprocess.call([r'C:\\flask_sample\\matrix.bat'])

if __name__ == "__app__":
    app.run(debug=True)

home.html（包含应该从哪里获取参数的表单）

            </div>
    </div>
</body>
<script type="text/javascript">
function create_command()
{
    if(document.getElementById('vmlinux').value=="")
    {
        document.getElementById('appended_command').innerHTML = "python adspcrashman.py -t " + document.getElementById('target_chipset').value + " -d " 
        + document.getElementById('ram_dump').value + " -o " + document.getElementById('output').value + " -b " 
        + document.getElementById('build').value + " -e " + document.getElementById('elf').value;
    }
    else
    {
        document.getElementById('appended_command').innerHTML = "python adspcrashman.py -t " + document.getElementById('target_chipset').value + " -d " 
        + document.getElementById('ram_dump').value + " -o " + document.getElementById('output').value + " -b " 
        + document.getElementById('build').value + " -e " + document.getElementById('elf').value + " -smmu64 "
        +document.getElementById('vmlinux').value;
    }  
}
</script>
</html>

现在烧瓶代码将只运行一个 .bat 文件（在线找到https://datatofish.com/batch-file-from-python/），该文件当前位于同一系统中，因此是直接路径。但是返回请求应该做的是运行上面提到的两个命令或者发送一个bat文件（包含两个命令）给用户在他/她的系统中运行它。在这种情况下我能做什么？

解决方案

到目前为止，以下代码似乎正在运行，至少对于在 localhost 上托管服务器。

@app.route("/person", methods =['POST','GET'])
def person():
    if request.method == 'POST':
            f = open ("crashman.bat","w+")
            f.write("@echo off\r\n")
            f.write("PUSHD \\\\rover\hyd_dspfw\ADSP_Tools\TriageTeam\Crashman\Latest\r\n")
            if request.form['Vmlinux'] == '':
                f.write("python adspcrashman.py -t " + request.form['target']+ " -d " + request.form['dump'] + " -o " + request.form['Output'] + " -b " + request.form['Build'] + " -e " + request.form['Elf'])
            else:
                f.write("python adspcrashman.py -t " + request.form['target']+ " -d " + request.form['dump'] + " -o " + request.form['Output'] + " -b " + request.form['Build'] + " -e " + request.form['Elf'] + " -smmu64 " + request.form['Vmlinux'])
            f.close()
            return subprocess.call([r'crashman.bat'])
