一、请求相关信息
1. 请求参数
1. request.method - 请求方法
2. request.args - get请求的参数
3. request.form - post请求的参数
4. request.values - 所有的请求参数
5. request.cookies
6. request.headers
7. request.path
8. request.full_path
9. request.script_root
10.request.url
11.request.base_url
12.request.url_root
13.request.host_url
14.request.host
15.request.remote_addr - 获取ip
2. 示例
1. 获取单个值
request.args.get('id')
2. 获取多个值
request.args.getlist('ids')
3. 将参数转换为字典
data = request.args
data_dict = data.to_dict()
4. 获取文件
f = request.files['the_file']
f.save('/var/www/uploads/uploaded_file.txt')
5. 如果想要知道文件上传之前其在客户端系统中的名称,使用filename属性
f = request.files['the_file']
f.save('/var/www/uploads/' + secure_filename(f.filename))
二、响应相关信息
1. 返回模式
1. return '字符串' - 实际上是调用make_response
2. return render_template('html模板路径', {})
3. return redirect('/index.html')
4. jsonify - 返回json数据
from flask import jsonify
return jsonify(**dict)
2. make_response
1. 响应中加入信息,基于make_response
from flask import make_response, render_template
# response是flask.wrappers.Response类型
response = make_response(render_template('index.html'))
response.set_cookie('key', 'value')
response.delete_cookie('key')
response.headers['X-Something'] = 'A value'
from flask import Flask, make_response
app = Flask(__name__)
def auth_decorator(func):
def inner(*args, **kwargs):
print('装饰器')
return func(*args, **kwargs)
return inner
@app.route('/index', endpoint='index', methods=['GET'])
@auth_decorator
def index():
response = make_response('index')
response.headers['hhhh'] = 'asdsad'
return response
if __name__ == '__main__':
app.run()
