如何在Flask Python中修复“找不到此页面”？
如何在Flask Python中修复“找不到此页面”？
提问于 2019-06-21 05:22:19
我正在Flask中为API设置一个新服务器。还有一个服务器来渲染Flask的前端。好吧，所以当我向确定API路线发出请求时，我得到了这个奇怪的回答“找不到这个页面”。我似乎真的好好怎样才能调试这个bug？其他奇怪的是它总是给我200状态。错误在路线中：@ app.route（'/ v1.0 / aluno / update /'，methods = ['POST']）
API SIDE
@app.route('/v1.0/aluno/<int:aluno_id>', methods=['GET'])
def aluno(aluno_id):
if request.method == 'GET':
cur = mysql.connection.cursor()
query = "SELECT NOME, NUMERO, PASSWORD FROM aluno WHERE NUMERO=%s"
cur.execute(query, (aluno_id,))
data = cur.fetchall()
if len(data) <= 0:
return Response(status=404)
else:
aluno = {
'nome': data[0][0],
'numero': data[0][1],
'password': data[0][2]
}
js = json.dumps(aluno)
resp = Response(js, status=200, mimetype='application/json')
resp.headers['Links'] = 'http://127.0.0.1/aluno'
return resp
@app.route('/v1.0/aluno/delete/<int:aluno_id>', methods=['POST'])
def aluno_delete(aluno_id):
if request.method == 'POST' and request.form['_method'] == 'delete':
query = "DELETE FROM aluno WHERE NUMERO = %s"
cur = mysql.connection.cursor()
cur.execute(query, (aluno_id,))
mysql.connection.commit()
cur.fetchall()
cur.close()
return Response(status=200)
@app.route('/v1.0/aluno/update/<int:aluno_id>', methods=['POST'])
def aluno_update(aluno_id):
form = AlunoForm(request.form)
if request.method == 'POST' and form.validate():
nome = request.form["nome"]
numero = request.form["numero"]
password = request.form["password"]
cur = mysql.connection.cursor()
query = "UPDATE aluno SET NOME=%s, NUMERO=%s, PASSWORD=%s WHERE NUMERO = %s"
cur.execute(query, (nome, numero, password, aluno_id))
mysql.connection.commit()
cur.execute(
"SELECT NOME, NUMERO FROM aluno WHERE NUMERO = %s", (aluno_id,))
data = cur.fetchall()
cur.close()
print(" * DATA ")
print(data)
aluno = {
'nome': data[0][0],
'numero': data[0][1]
}
js = json.dumps(aluno)
resp = Response(js, status=200, mimetype='application/json')
resp.headers['Links'] = 'http://127.0.0.1/aluno'
return resp
elif request.method == 'POST' and not form.validate():
resp = Response(status=400)
resp.headers['Links'] = 'http://127.0.0.1/aluno'
return resp

我尝试过使用POSTMAN而不是常规的Web浏览器。向API发出请求。但我得到相同的回答：'找不到此页面'
至少我期待某种400 Bad Request或类似的东西。

表单验证失败，您将根据以下代码获得400
elif request.method == 'POST' and not form.validate():
resp = Response(status=400)
resp.headers['Links'] = 'http://127.0.0.1/aluno'
return resp
