我们先来看一下效果（简单的写了一个）:
原理: 将post请求的代码数据写入了服务器的一个文件，然后用服务器的python编译器执行返回结果
实现代码：
＃flaskrun.py# -*- coding: utf-8 -*-# __author__="ZJL"from flask import Flaskfrom flask import requestfrom flask import Responseimport jsonimport zxbyapp = Flask(__name__)def Response_headers(content): resp = Response(content) resp.headers['Access-Control-Allow-Origin'] = '*' return resp@app.route('/')def hello_world(): return Response_headers('hello world!!!')@app.route('/run', methods=['POST'])def run(): if request.method == 'POST' and request.form['code']: code = request.form['code'] print(code) jsondata = zxby.main(code) return Response_headers(str(jsondata))@app.errorhandler(403)def page_not_found(error): content = json.dumps({"error_code": "403"}) resp = Response_headers(content) return resp@app.errorhandler(404)def page_not_found(error): content = json.dumps({"error_code": "404"}) resp = Response_headers(content) return resp@app.errorhandler(400)def page_not_found(error): content = json.dumps({"error_code": "400"}) resp = Response_headers(content) return resp@app.errorhandler(405)def page_not_found(error): content = json.dumps({"error_code": "405"}) resp = Response_headers(content) return resp@app.errorhandler(410)def page_not_found(error): content = json.dumps({"error_code": "410"}) resp = Response_headers(content) return resp@app.errorhandler(500)def page_not_found(error): content = json.dumps({"error_code": "500"}) resp = Response_headers(content) return respif __name__ == '__main__': app.run(debug=True)
#zxby.py# -*- coding: utf-8 -*-# __author__="ZJL"import os, sys, subprocess, tempfile, time# 创建临时文件夹,返回临时文件夹路径TempFile = tempfile.mkdtemp(suffix='_test', prefix='python_')# 文件名FileNum = int(time.time() * 1000)# python编译器位置EXEC = sys.executable# 获取python版本def get_version(): v = sys.version_info version = "python %s.%s" % (v.major, v.minor) return version# 获得py文件名def get_pyname(): global FileNum return 'test_%d' % FileNum# 接收代码写入文件def write_file(pyname, code): fpath = os.path.join(TempFile, '%s.py' % pyname) with open(fpath, 'w', encoding='utf-8') as f: f.write(code) print('file path: %s' % fpath) return fpath# 编码def decode(s): try: return s.decode('utf-8') except UnicodeDecodeError: return s.decode('gbk') # 主执行函数def main(code): r = dict() r["version"] = get_version() pyname = get_pyname() fpath = write_file(pyname, code) try: # subprocess.check_output 是 父进程等待子进程完成，返回子进程向标准输出的输出结果 # stderr是标准输出的类型 outdata = decode(subprocess.check_output([EXEC, fpath], stderr=subprocess.STDOUT, timeout=5)) except subprocess.CalledProcessError as e: # e.output是错误信息标准输出 # 错误返回的数据 r["code"] = 'Error' r["output"] = decode(e.output) return r else: # 成功返回的数据 r['output'] = outdata r["code"] = "Success" return r finally: # 删除文件(其实不用删除临时文件会自动删除) try: os.remove(fpath) except Exception as e: exit(1)if __name__ == '__main__': code = "print(11);print(22)" print(main(code)) 运行app.run()方法，通过post提交代码，就ok了。我们可以对输出结过做进一步的处理，我这只是为了解一下原理，就没继续了。
