FastAPI和SlowAPI不適用于Ajax和getJSON請求-python-有解無憂

我有問題。當我正確地從瀏覽器或郵遞員發出太多請求時，API (slowapi) 會阻止我，因為我已正確設定，但如果我通過 AJAX 和 jquery 的 $ .getJSON 發出請求，API 不會阻止我。我該如何解決？我的代碼（從完整代碼中提取）：

from fastapi import FastAPI, Request, Response, status
from fastapi.middleware.cors import CORSMiddleware
from slowapi import Limiter, _rate_limit_exceeded_handler
from slowapi.util import get_remote_address
from slowapi.errors import RateLimitExceeded
from slowapi.middleware import SlowAPIMiddleware
limiter = Limiter(key_func=get_remote_address, default_limits=["2/5seconds"])
app = FastAPI()
app.state.limiter = limiter
app.add_exception_handler(RateLimitExceeded, _rate_limit_exceeded_handler)
app.add_middleware(
    CORSMiddleware,
    allow_origins=origins,
    allow_credentials=True,
    allow_methods=["*"],
    allow_headers=["*"],
)
app.add_middleware(SlowAPIMiddleware)

@app.get('/schools/{regione}/{provincia}/{comune}')
def search_school(request: Request, response: Response, regione: str, provincia: str, comune: str):
    if(request.headers.get("Provider") == "Test-User-Provider"):
        return {"message": "OK", "status": "success", "code": 200}

    else:
        response.status_code = status.HTTP_400_BAD_REQUEST
        return {"message": "Provider not found", "status": "error", "code": 400}

瀏覽器結果（作業）：

{"error":"Rate limit exceeded: 2 per 5 second"}

jQuery代碼（不作業）：

$.getJSON(apiURL "/schools/Test/Test/Test", function(data) {
        console.log(data)
});

顯然，使用 jquery，我嘗試每秒發出很多請求控制臺瀏覽器結果（不限于！）：

{message: '...', status: 'success', code: 200}

FastAPI 和 SlowAPI 不適用于 Ajax 和 getJSON 請求 - python

萬分感謝。

更新通過 jquery 我嘗試向其他路徑發出請求，并且它是正確的速率限制。如果我向此路徑發出請求，/schools/{region}/{province}/{municipality}則速率限制不起作用

更新 2

I refer the updated and tested code. When I send a request to path /testpath /{region} it is correctly rate-limited. If instead I send a request to some sub-paths (/schools/{region}/{province}/{municipality} it is not rate-limited.

The jQuery code is the same as listed above

from fastapi import FastAPI, Request, Response, status
from fastapi.middleware.cors import CORSMiddleware
from slowapi import Limiter, _rate_limit_exceeded_handler
from slowapi.util import get_remote_address
from slowapi.errors import RateLimitExceeded
from slowapi.middleware import SlowAPIMiddleware

limiter = Limiter(key_func=get_remote_address, default_limits=["2/5seconds"])
app = FastAPI()
app.state.limiter = limiter
app.add_exception_handler(RateLimitExceeded, _rate_limit_exceeded_handler)

origins = ["http://127.0.0.1/", "http://localhost", "http://192.168.1.75"] ## CORS

app.add_middleware(
    CORSMiddleware,
    allow_origins=origins,
    allow_credentials=True,
    allow_methods=["*"],
    allow_headers=["*"],
)
app.add_middleware(SlowAPIMiddleware) ## Rate-limit all request

@app.get('/schools/{regione}/{provincia}/{comune}')
def search_school(request: Request, response: Response, regione: str, provincia: str, comune: str):
        return {"message": 'No schools found!', "status": 'error', "code": 200} ## Or if found return schools informations

@app.get('/testpath/{regione}') ## Works with one path. If I add "provincia" and "comune" non work
def search_school(request: Request, response: Response, regione: str, provincia: str, comune: str):
        return {"message": 'No schools found!', "status": 'error', "code": 200} ## Or if found return schools informations

If i use schools path: FastAPI 和 SlowAPI 不適用于 Ajax 和 getJSON 請求 - python

If i use testpath it's correct rate-limited: FastAPI 和 SlowAPI 不適用于 Ajax 和 getJSON 請求 - python

uj5u.com熱心網友回復：

測驗您的代碼并且作業正常，只要您在方法”中用直雙引號替換結束雙引號："getJSON()

$.getJSON(apiURL   "/security/validate_token", function(data) {
        console.log(data)
});

您在上面寫了“狀態回應是個性化的，我自己決定”。因此，如果您仍然收到{message: '...', status: 'success', code: 200}回復，我建議您嘗試回傳一條簡單的訊息，例如，return {"status": "success"}并查看它是否按預期作業。如果不是，則可能是您的自定義回應中沒有以正確的方式實施。

更新

以下應該按預期作業。如果不是，那么問題可能出在您的問題中未包含的代碼中的其他地方。我還建議將它作為模板添加到您的應用程式中，因為從您發布的錯誤來看，您似乎收到了Cross-Origin警告。
