我尝试连接到MySQL,它没有显示用户添加的成功状态,我收到以下错误:
{"message": "The method is not allowed for the requested URL."}
我不明白它所说的“方法”是什么...... POST我正在使用POSTMAN?一些帮助将不胜感激!
所以我改变我的代码把MySQL()放在POST方法中,我仍然得到同样的错误....
这是我的“api.py”代码:
from flask import Flask
from flask_restful import Resource, Api, reqparse
from flaskext.mysql import MySQL
app = Flask(__name__)
api = Api(app)
class CreateUser(Resource):
def post(self):
try:
# Parse the arguments
parser = reqparse.RequestParser()
parser.add_argument('email', type=str, help='Email address to create user')
parser.add_argument('password', type=str, help='Password to create user')
args = parser.parse_args()
_userEmail = args['email']
_userPassword = args['password']
return {'Email': args['email'], 'Password': args['password']}
mysql = MySQL()
# MySQL configurations
app.config['MYSQL_DATABASE_USER'] = 'root'
app.config['MYSQL_DATABASE_DB'] = 'itemlistdb'
app.config['MYSQL_DATABASE_HOST'] = 'localhost'
mysql.init_app(app)
conn = mysql.connect()
cursor = conn.cursor()
cursor.callproc('spCreateUser',(_userEmail,_userPassword))
data = cursor.fetchall()
if len(data) is 0:
conn.commit()
return {'StatusCode':'200','Message': 'User creation success'}
else:
return {'StatusCode':'1000','Message': str(data[0])}
except Exception as e:
return {'error': str(e)}
api.add_resource(CreateUser, '/CreateUser')
if __name__ == '__main__':
app.run(debug=True)
我使用存储过程在db中写入值,过程是spCreateUser,这里是代码:
BEGIN
if ( select exists (select 1 from tblUser where UserName = p_username) )
THEN
select 'Username Exists !!';
ELSE
insert into tblUser(
UserName,
Password
)
values
(
p_Username,
p_Password
);
END IF;
END

如果使用不受支持的HTTP方法调用资源,API将返回状态为405 Method Not Allowed的响应。
我猜你试图在浏览器上查看你的资源,所以你有这个错误。如果您想在浏览器上查看资源,则必须支持http get
方法。
class CreateUser(Resource):
def post(self):
cur.execute("INSERT INTO table VALUES(?,?)",(email,password))
def get(self):
#...
还有一个QueryDb
方法不会被self调用,你必须在http方法中调用它。

好的,我解决了所有问题......可能对其他人有用:
首先我把这个函数的名字放在" post"不是"发布"。
然后我收到以下消息:
"在处理完第一个请求后调用了一个设置函数"
解决这个问题的方法是禁用调试模式......
所以这里的代码正在运行:
from flask import Flask
from flask_restful import Resource, Api, reqparse
from flaskext.mysql import MySQL
app = Flask(__name__)
api = Api(app)
class CreateUser(Resource):
def post(self):
try:
# Parse the arguments
parser = reqparse.RequestParser()
parser.add_argument('email', type=str, help='Email address to create user')
parser.add_argument('password', type=str, help='Password to create user')
args = parser.parse_args()
_userEmail = args['email']
_userPassword = args['password']
#return {'Email': args['email'], 'Password': args['password']}
mysql = MySQL()
# MySQL configurations
app.config['MYSQL_DATABASE_USER'] = 'root'
app.config['MYSQL_DATABASE_DB'] = 'itemlistdb'
app.config['MYSQL_DATABASE_HOST'] = 'localhost'
mysql.init_app(app)
conn = mysql.connect()
cursor = conn.cursor()
cursor.callproc('spCreateUser',(_userEmail,_userPassword))
data = cursor.fetchall()
if len(data) is 0:
conn.commit()
return {'StatusCode':'200','Message': 'User creation success'}
cursor.close()
conn.close()
else:
return {'StatusCode':'1000','Message': str(data[0])}
cursor.close()
conn.close()
except Exception as e:
return {'error': str(e)}
api.add_resource(CreateUser, '/CreateUser')
if __name__ == '__main__':
app.run(debug=False)
