当用户访问我在烧瓶应用程序上运行的此URL时,我希望Web服务能够处理问号后指定的参数:
http://10.1.1.1:5000/login?username=alex&password=pw1
#I just want to be able to manipulate the parameters
@app.route('/login', methods=['GET', 'POST'])
def login():
username = request.form['username']
print(username)
password = request.form['password']
print(password)

使用request.args
获取查询字符串的已解析内容:
from flask import request
@app.route(...)
def login():
username = request.args.get('username')
password = request.args.get('password')

request.args
中提供了网址参数,MultiDict是一个MIME types,其get
方法,默认值(default
)和类型({的可选参数{1}}) - 可调用,将输入值转换为所需格式。
type
上述代码示例:
from flask import request
@app.route('/my-route')
def my_route():
page = request.args.get('page', default = 1, type = int)
filter = request.args.get('filter', default = '*', type = str)

您还可以使用括号<>在视图定义的URL上,此输入将进入您的视图函数参数
@app.route('/<name>')
def my_view_func(name):
return name

如果您在URL中传递了一个参数,则可以按照以下步骤进行操作
from flask import request
#url
http://10.1.1.1:5000/login/alex
from flask import request
@app.route('/login/<username>', methods=['GET'])
def login(username):
print(username)
如果您有多个参数:
#url
http://10.1.1.1:5000/login?username=alex&password=pw1
from flask import request
@app.route('/login', methods=['GET'])
def login():
username = request.args.get('username')
print(username)
password= request.args.get('password')
print(password)
在POST请求的情况下,您尝试执行的操作将参数作为表单参数传递并且不出现在URL中。如果您实际上正在开发登录API,建议您使用POST请求而不是GET,然后将数据公开给用户。
在发布请求的情况下,其工作方式如下:
#url
http://10.1.1.1:5000/login
HTML片段:
<form action="http://10.1.1.1:5000/login">
Username : <input type="text" name="username"><br>
Password : <input type="password" name="password"><br>
<input type="submit" value="submit">
</form>
路线:
from flask import request
@app.route('/login', methods=['POST'])
def login():
username = request.form.get('username')
print(username)
password= request.form.get('password')
print(password)

URL:
http://0.0.0.0:5000/user/name/
代码:
@app.route('/user/< string:name >/', methods=['GET', 'POST'])
def user_view(name):
print(name)
答案 5 :(得分:1)
这应该有效
@app.route('/login$username=<username>$password=<password>', methods=['GET', 'POST'])
def login(username, password):
# you can add stuff
return f"Username: {username}\nPassword: {password}"

这真的很简单。让我将此过程分为两个简单步骤。
在html模板上,您将用户名和密码的名称标签声明为
<form method="POST">
<input type="text" name="user_name"></input>
<input type="text" name="password"></input>
</form>
然后,将您的代码修改为:
from flask import request
@app.route('/my-route', methods=['POST']) #you should always parse username and
# password in a POST method not GET
def my_route():
username = request.form.get("user_name")
print(username)
password = request.form.get("password")
print(password)
#now manipulate the username and password variables as you wish
#Tip: define another method instead of methods=['GET','POST'], if you want to
# render the same template with a GET request too

使用request.args.get(param)
,例如:
http://10.1.1.1:5000/login?username=alex&password=pw1
@app.route('/login', methods=['GET', 'POST'])
def login():
username = request.args.get('username')
print(username)
password = request.args.get('password')
print(password)
