问题描述
我正在尝试使用Flask-RESTful实现REST API。我的API包含4个请求：GET，POST，PUT，DELETE。除PUT请求外，其他所有功能均正常运行。它会继续返回状态代码404，但找不到请求的URL。我正在使用Postman测试我的API。这是我的代码。可以告诉我我在哪里做错了吗？谢谢！
# Small API project using Flask-RESTful
from flask import Flask,request
from flask_restful import Resource,Api,reqparse
from flask_jwt import JWT,jwt_required
app = Flask(__name__)
# Encrypted key
app.secret_key = "Nam Dao"
api = Api(app)
students = []
class Student(Resource):
parser = reqparse.RequestParser()
parser.add_argument("major",type=str,required=True,help="This field cannot be left blank")
def get(self,name):
# filter function will return a filter object
# next function will get the "next" student in the filter object.
# if the Next function does not return anything => return None.
for student in students:
if student["name"] == name:
return student,200
return {"message": "student not found"},404
def post(self,name):
if next(filter(lambda x: x["name"] == name,students),None) is not None:
return {"message": f"A student with the name {name} already exists"},400
request_data = self.parser.parse_args()
print(request_data)
student = {"name": name,"major": request_data["major"]}
students.append(student)
return student,201
def delete(self,name):
for student in students:
if student["name"] == name:
students.remove(student)
return {"message": "Item deleted"},200
return {"message": "No student found"},204
def put(self,name):
data = request.get_json()
for student in students:
if student["name"] == name:
student["major"] = data["major"]
return {"message": "Student Major Changed"},200
student = {"name": data["name"],"major": data["major"]}
students.append(student)
return {"message": "Student Added"},200
api.add_resource(Student,"/student/<string:name>")
class StudentsList(Resource):
def get(self):
return {"students": students},200
api.add_resource(StudentsList,"/students")
if __name__ == '__main__':
app.run(debug=True)
解决方法
我再次重新检查我的URL，但是我遗漏了字母，这就是为什么它返回404状态代码的原因。这是一个非常愚蠢的错误。一切都很好
