【python】简单使用tornado web

官网

http://www.ttlsa.com/docs/tornado/#_4

安装

pip3 install tornado

设置请求头

请求头最好设置utf-8，否则容易出中文转码错误

def set_default_header(self):
    # 后面的*可以换成ip地址，意为允许访问的地址
    self.set_header('Access-Control-Allow-Origin', '*')
    self.set_header('Access-Control-Allow-Headers', 'x-requested-with')
    self.set_header('Access-Control-Allow-Methods', 'POST, GET, PUT, DELETE')
    self.set_header("Content-Type", "application/json;charset=UTF-8")

从url传参

class UrlHandler(RequestHandler):
    """从url传参"""
    def get(self, story_id):
        self.write("You requested the story " + story_id)

效果

从param传参

class ParamHandler(RequestHandler):
    """从param传参"""
    def get(self):
        arr = self.get_argument("arr")
        if arr:
            print('arr = ', arr, type(arr))
            arr = eval(arr)  # 字符转列表
            print('arr = ', arr, type(arr))
        self.write("You requested the story " + arr)

效果

从body传参

class GetArrHandle(RequestHandler):
    """从body传参"""
    def get(self):
        data = json.loads(self.request.body)
        project_id = data['project_id']
        if project_id:
            print('project_id = ', project_id, type(project_id))
        result = {
            "code": 0 if project_id >= 0 else 1,
            "msg": f"执行完成，project_id:{project_id}"
        }
        self.write(json.dumps(result, ensure_ascii=False))
