我有一個接受 JSON 的端點(diǎn)api.add_resource(EventsList, '/events')Flask Restful / SQL Alchemy 是：class EventsList (Resource): #RETURNS ALL EVENTS def get(self): schema = EventSchema() result = db.session.query(EventModel).all() return schema.dump(result, many=True), 200 #POSTS A SINGLE EVENT def post(self): title = request.json['title'] date = request.json['date'] event = EventModel(title=title,date=date) db.session.add(event) db.session.commit() data = ({'title': event.title, 'date': event.date}) response = jsonify(data) response.status_code = 200 return response當(dāng)通過命令行使用curl時，這絕對可以正常工作：卷曲請求curl http://localhost:5002/events -H "Content-Type: application/json" -d '{"title": "TEst Event 3", "date":"2020-02-23"}'卷曲響應(yīng)響應(yīng)包含預(yù)期的數(shù)據(jù)：{"date":"Sun, 23 Feb 2020 00:00:00 GMT","title":"TEst Event 3"}這一切都很好。但是，當(dāng)我嘗試從 Python 執(zhí)行此操作時，我收到服務(wù)器錯誤。Pythonimport importlibimport subprocessimport csvimport sysimport requeststargetWikiPage = input("Target Wiki Page: ")eventTitle = input("Event Title: ")eventDate = input("Event Date: ") #POST AN EVENTdata = '{"title": "'+eventTitle+'","date":"'+eventDate+'"}'print("SENDING EVENT DATA:")print(requests.body)print(requests.headers)response = requests.post("http://localhost:5002/events", json=data)任何幫助表示贊賞。

修復(fù)了這個問題。
問題在于我如何將數(shù)據(jù)發(fā)送到服務(wù)器。這就是我所擁有的：
targetWikiPage = input("Target Wiki Page: ")
eventTitle = input("Event Title: ")
eventDate = input("Event Date: ")
#POST AN EVENT
data = '{"title": "'+eventTitle+'","date":"'+eventDate+'"}'
print("SENDING EVENT DATA:")
print(requests.body)
print(requests.headers)
response = requests.post("http://localhost:5002/events", json=data)
請注意，我的requests.post有兩個值被傳遞。網(wǎng)址和數(shù)據(jù)。
問題如下：
數(shù)據(jù)格式不正確。這應(yīng)該是：
data = json.dumps({"title": eventTitle, "date": eventDate})
我需要添加標(biāo)題：
headers = {'Content-type': 'application/json', 'Accept': 'text/plain'}
我需要將一個
data值傳遞給服務(wù)器，而不是json
requests.post("http://localhost:5002/events", headers=headers, data=data)
這將我的文件更改為：
targetWikiPage = input("Target Wiki Page: ")
eventTitle = input("Event Title: ")
eventDate = input("Event Date: ")
#POST AN EVENT
data = json.dumps({"title": eventTitle, "date": eventDate})
headers = {'Content-type': 'application/json', 'Accept': 'text/plain'}
print(data)
print(headers)
print("SENDING EVENT DATA:")
response = requests.post("http://localhost:5002/events", headers=headers, data=data)
json=json.loads(response.content)

您在字符串對象中有 JSON 數(shù)據(jù)。嘗試通過字符串的鍵從字符串中提取值將產(chǎn)生您所描述的錯誤
>>> response = '{"date":"Sun, 23 Feb 2020 00:00:00 GMT","title":"TEst Event 3"}'
>>> response_date = response["date"]
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
response_date = response["date"]
TypeError: string indices must be integers
您需要先將字符串轉(zhuǎn)換為a dict，然后提取值
>>> import json
>>> response_as_json = json.loads(response)
>>> response_date = response_as_json["date"]
>>> response_date
'Sun, 23 Feb 2020 00:00:00 GMT'
