get/post与测试

get请求,蓝图文件：

from flask import Blueprint,request
index_page = Blueprint("index_page",__name__)
@index_page.route('/')
def index():
    return "index page"
@index_page.route('/me')
def hello():
    return "hello, this is me"
@index_page.route('/get')
def get():
    var_a = request.args.get('a','Welcom')
    return 'request:%sparams:%s,var_a:%s'%(request.method,request.args,var_a)

访问127.0.0.1/learning/get?a=Tom时 ，浏览器的显示：

post请求：

from flask import Blueprint,request


index_page = Blueprint("index_page",__name__)

@index_page.route('/')
def index():
    return "index page"


@index_page.route('/me')
def hello():
    return "hello, this is me"

@index_page.route('/get')
def get():
    var_a = request.args.get('a','Welcom')
    return 'request:%sparams:%s,var_a:%s'%(request.method,request.args,var_a)


@index_page.route('/post',methods=['POST'])
def post():
    var_b = request.values['b'] if 'b' in request.values else 'welcome'
    return 'request: %s; params: %s; var_b: %s;%s'%(request.method,request.args,var_b,request.values)

如何既取到post的form的值，又能取到get的args的值:request.values【源码中values封装了两个变量的值，类型是CombinedMultiDict】不过不知道是不是升级了，我这里看的时候，from已经是空的了，从request.args中也能取到post的值。

返回结果：

使用post方法获取文件上传：
enctype = “multiport/form-data”

from flask import Blueprint,request


index_page = Blueprint("index_page",__name__)

@index_page.route('/')
def index():
    return "index page"


@index_page.route('/me')
def hello():
    return "hello, this is me"

@index_page.route('/get')
def get():
    var_a = request.args.get('a','Welcom')
    return 'request:%sparams:%s,var_a:%s'%(request.method,request.args,var_a)


@index_page.route('/post',methods=['POST'])
def post():
    var_b = request.values['b'] if 'b' in request.values else 'welcome'
    return 'request: %s; params: %s; var_b: %s;%s'%(request.method,request.args,var_b,request.values)



@index_page.route('/upload',methods=['POST'])
def upload():
    var_c = request.files['file'] if 'file' in request.files else None
    return 'request: %s; params: %s; var_c: %s; values:%s'%(request.method,request.files,var_c,request.values)

测试

post工具：curl，postman

curl

get:
curl "http://127.0.0.1:5000/learning/get?a=Tom"

post:
curl "http://127.0.0.1:5000/learning/post" -X POST -d "b=Jerry"
-X表示方法，-d表示参数

postman

也可以通过postman的功能展示curl的写法：
