我正在使用Bottle和MongoDB创建REST服务。问题是尝试插入文档时出现500错误代码。
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

<title>Error: 500 Internal Server Error</title>
<style type="text/css">

</head>
<body>
<h1>Error: 500 Internal Server Error</h1>

curl -H "Content-Type: application/json" -X POST -d '{"id" : "10011-2017-TEST","certificate_number" : 9278833,"business_name" : "ACME TEST INC.","date" : "Feb 20 2017","result" : "No Violation Issued","sector" : "Test Retail Dealer - 101"}' http://localhost:8080/create
事实是，即使得到500错误代码，我仍然能够成功插入文档。为什么会收到500错误代码？我一直在尝试为MongoDB和Bottle实施异常处理。不知道这就是为什么我要获取代码。如果没有，如何正确实施异常处理？我已经阅读了中止的内容，但是对此有麻烦。另外，当我注释掉return result时，我得到200的响应代码，但是我想返回插入的文档的ID。谢谢

from bottle import route, run, request, abort, post, error

connection = MongoClient('localhost', 27017)
db = connection['city']
collection = db['inspections']
@route('/create', method='POST')
def insert_document():
try:
data = request.json
result = collection.insert_one(data).inserted_id
except Exception, e:
print ('EXCEPTION: ', e)
return result
if __name__ == '__main__':
run(host='localhost', port=8080)
更改
return result
to
return str(result)
或完全删除该行。
