我有一个配置了一些CORS选项的Flask-Restful API：
api = Api()
api.decorators=[cors.crossdomain(origin=’*’, headers=[‘accept’, ‘Content-Type’])]
…
api.init_app(app)
我的API接受POST请求,如果请求中的数据无效,则可能会失败：
class myAPI(Resource):
def post(self):
args = request.get_json()
if args.get(‘something’):
return {‘message’: ‘Request worked, data received!’,
‘something’: args[‘something’]}
else:
abort(500, “Error: Data must contain a ‘something’ field!”)
当我对我的API发出成功的POST请求时,我可以看到CORS选项已正确设置：
…
* upload completely sent off: 81 out of 81 bytes
* HTTP 1.0, assume close after body
< HTTP/1.0 200 OK
< Content-Type: application/json
< Content-Length: 205
< Access-Control-Allow-Origin: *
< Access-Control-Allow-Methods: HEAD, GET, POST, OPTIONS
< Access-Control-Max-Age: 21600
< Access-Control-Allow-Headers: ACCEPT, CONTENT-TYPE
< Server: Werkzeug/0.9.4 Python/2.7.6
但是,如果我的类中的post调用通过abort方法退出(通过故意将错误数据发送到请求),则响应中缺少Access-Control- *字段：
* upload completely sent off: 75 out of 75 bytes
* HTTP 1.0, assume close after body
< HTTP/1.0 500 INTERNAL SERVER ERROR
< Content-Type: application/json
< Content-Length: 51
< Server: Werkzeug/0.9.4 Python/2.7.6
是否有可能使中止方法与我的CORS规则一致,或者我应该创建自己的完整响应并避免使用中止函数？
