当用户访问我的flask应用程序上运行的这个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)
当前回答
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)
(编辑:删除格式字符串中的空格)
其他回答
这应该可以
@app.route('/login$username=<username>$password=<password>', methods=['GET', 'POST'])
def login(username, password):
# you can add stuff
return f"Username: {username}\nPassword: {password}"
URL参数在request中可用。args是一个ImmutableMultiDict，它有一个get方法，有默认值(default)和类型(type)的可选参数——这是一个可调用对象，它将输入值转换为所需的格式。(有关详细信息，请参阅该方法的文档。)
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)
上面代码的示例:
/my-route?page=34 -> page: 34 filter: '*'
/my-route -> page: 1 filter: '*'
/my-route?page=10&filter=test -> page: 10 filter: 'test'
/my-route?page=10&filter=10 -> page: 10 filter: '10'
/my-route?page=*&filter=* -> page: 1 filter: '*'
如果你在URL中传递了一个参数，你可以这样做
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)
如果你有多个参数:
#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请求中，参数作为表单参数传递，而不出现在URL中。在实际开发登录API的情况下，使用POST请求而不是GET请求并将数据公开给用户是明智的。
如有职位要求，其工作方式如下:
#url
http://10.1.1.1:5000/login
HTML代码片段:
<form action="http://10.1.1.1:5000/login" method="POST">
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)
(编辑:删除格式字符串中的空格)
使用请求。获取查询字符串的解析内容:
from flask import request
@app.route(...)
def login():
username = request.args.get('username')
password = request.args.get('password')
