python/flask get/post 不同请求头格式

如下：

```python
from flask import request
import flask
server = flask.Flask(__name__)
@server.route('/argslogin', methods=['get'])
def test_args():
    #表单格式
    ad = request.args.get('admin')
    ps = request.args['ps']
    print(ad,ps)
    return {'ad':ad,'ps':ps}
@server.route('/jsonlogin', methods=['post'])
def test_josn():
    #json格式
    ad = request.json.get('admin')
    ps = request.json['ps']
    print(ad,ps)
    return {'ad':ad,'ps':ps}
@server.route('/formlogin', methods=['post'])
def test_form():
    #表单格式
    ad = request.form.get('admin')
    ps = request.form['ps']
    print(ad,ps)
    return {'ad':ad,'ps':ps}
if __name__ == '__main__':
    server.run(debug=True, host='0.0.0.0', port=8080)
