flask_restful.abort = api_abort def api_abort( httpcode=400, errcode=None, message=None, key=""): res = BaseResponse() res.errcode = errcode or 4011 if message: res.errmsg = message else: res.errmsg = key + codetype.get(res.errcode) res.dict.pop('data') if httpcode == 200: print(123456, res.dict) return jsonify(res.dict), httpcode return abort( httpcode, **res.dict) 

@app.after_request def after_request(response): # 允许跨域 response.headers.add('Access-Control-Allow-Origin', '*') if request.method == 'OPTIONS': response.headers['Access-Control-Allow-Methods'] = 'POST, DELETE, PUT, GET' headers = request.headers.get('Access-Control-Request-Headers') if headers: response.headers['Access-Control-Allow-Headers'] = headers return response 

当 return abort( httpcode, **res.dict) 状态码 400 提示跨域
