我在创建React本机应用程序时遇到问题。我使用FastAPI作为后端。在对我的后端进行此调用时,什么也没有发生
function sendAkt() {
fetch("https://192.168.1.5:8000/newActivity", {
method: "POST",
headers: {
'Accept': "application/json",
"Content-Type": "application/json",
},
body: JSON.stringify({
name: ime,
desc: opis,
place: mjesto,
team: tim,
typeOf: pickerSel,
id: users.id,
}),
})
.then(_=> console.log('rea for the minute'))
.catch(e => console.log(e))
}
没有错误,后端控制台从不报告曾经调用后端路由。看来回程就要结束了。大约3分钟后,控制台会弹出此对话框
Network request failed

这是我呼叫的后端路线
@app.post('/newActivity')
async def unos(request: NewActivity):
print('route Reaches')
# name = request.name
# desc = request.desc
# place = request.place
# team = request.team
# typeOf = request.typeOf
# id = request.id
# year = 10
# new_activity = Activities(activity_type_id=typeOf, academic_year_id=year,
# description=desc,
# user_id=id, team_id=team, title=name, location=place)
# session.add(new_activity)
# session.commit()
return JSONResponse(content='Uspijeh')
这是我后端的CORS设置
app.add_middleware(
CORSMiddleware,
allow_origins=['http://localhost:19001'],
allow_credentials=True,
allow_methods=["*"],
allow_headers=["*"],
)
我已经做了几个小时了,我不知道是什么导致了这个问题
真是愚蠢的问题。我用
https
而不是http. Changing to
