Flask学习笔记05之请求与响应

1. 请求
# request.method
# request.args
# request.form
# request.values
# request.cookies
# request.headers
# request.path
# request.full_path
# request.script_root
# request.url
# request.base_url
# request.url_root
# request.host_url
# request.host
# request.files
# obj = request.files['the_file_name'] #上传文件
# obj.save('/var/www/uploads/' + secure_filename(f.filename)) # 保存文件

2. 响应

响应体：
return “asdf” #字符串
return jsonify({'k1':'v1'})  # json字符串
return render_template('html模板路径')
return redirect('/index.html')

定制响应头：

# 通过make_response 对象来封装响应头和响应体
obj = make_response("响应体内容") 
obj.headers['xxxxxxx'] = '123'
obj.set_cookie('key', 'value')
return obj

from  flask import Flask, render_template, request, redirect, session, views, make_response, jsonify

app = Flask(import_name=__name__)
app.secret_key = 'flask'


# app.debug = True


@app.route('/index')
def index():
    print(dir(request))
    # 请求相关
    print(request.method)
    print(request.args)
    print(request.form)
    print(request.values)
    print(request.cookies)
    print(request.headers)
    print(request.path)
    print(request.full_path)
    print(request.script_root)
    print(request.url)
    print(request.base_url)
    print(request.url_root)
    print(request.host_url)
    print(request.host)

    # 响应
    dict = {'name': 'ok'}
    # response = make_response("123")
    response = make_response(jsonify(dict))
    response.set_cookie(key="name", value="admin")
    response.headers['age'] = 18
    return response 

if __name__ == '__main__':
    app.run()
