我有一个烧瓶应用程序,已部署到Heroku,其中一条路线如下
def get_kws():
seed_kw = request.json['firstParam']
audience_max = request.json['secondParam']
interest_mining_service = InterestMiningService(seed_kw, audience_max)
query_result = interest_mining_service.query_keyword().tolist()
if seed_kw in query_result:
print ("yes")
return jsonify(
{
'keyword_data' : interest_mining_service.find_kws().to_json(orient='records'),
'query_results': query_result
}
)
当我在本地测试此端点时,向该端点发送POST和GET请求时没有问题。但是,当我部署到Heroku时,出现以下错误:
File "/app/server/controller.py", line 24, in get_kws

我以前从未见过此错误Request object has no attribute 'is_xhr'
,并且似乎仅在我部署到Heroku时才发生。关于我应该研究什么的任何指导?
json键似乎也没有问题keyword_data
-问题似乎仅限于query_results
列表。
