我正在嘗試確保我已設置錯誤處理。我不確定我是否使用了 try、except 和 return 正確。所需的輸出是 True 或 False 如果文檔插入成功，則為 True，否則為 False。我做對了嗎？我擔心的是它總是會返回 true 嗎？不完全確定 try/except 是如何工作的。謝謝。import jsonimport pymongofrom bson import json_utilfrom pymongo import MongoClientfrom pymongo import errorsconnection = MongoClient('localhost', 27017)db = connection['city']collection = db['inspections']def insert_document(documentToInsert): try: collection.insert_one(documentToInsert) return True except WriteConcernError as wce: print(wce) return False except WriteError as we: print(we) return Falsedef main(): document = { "id" : "11111-2019-ENFO", "certificate_number" : 9278806, "business_name" : "TAXOLOGY", "date" : "Feb 20 2015", "result" : "No Violation Issued", "sector" : "Accounting - 111", "address" : { "city" : "MISSION HILLS", "zip" : 91401, "street" : "Sepulveda", "number" : 1809 } } print(insert_document(document))main()

我沒有看到任何write_concern被傳入作為您寫入的選項，我假設您可能看不到WriteConcernError. 檢查此：pymongo.write_concern.WriteConcern有關如何設置的示例WriteConcern。此外，僅當您想在發(fā)生某種類型的錯誤時執(zhí)行某些功能時才需要這些錯誤檢查，因為您只需要返回True/ False，那么您可以刪除所有這些錯誤檢查：
代碼 ：
connection = MongoClient('localhost', 27017)
db = connection['city']
collection = db['inspections']
def insert_document(documentToInsert):
try:
collection.insert_one(documentToInsert)
return True
except Exception as e:
print("An exception occurred ::", e)
return False
def main():
document = {
"id": "11111-2019-ENFO",
"certificate_number": 9278806,
"business_name": "TAXOLOGY",
"date": "Feb 20 2015",
"result": "No Violation Issued",
"sector": "Accounting - 111",
"address":
{
"city": "MISSION HILLS",
"zip": 91401,
"street": "Sepulveda",
"number": 1809
}
}
print(insert_document(document))
main()
