使用 laravel8 的 RateLimiter 对部分API做访问速率限制，记录了定义规则和在路由文件中使用。
定义速率限制规则，
在 app/Providers/RouteServiceProvider.php boot方法内定义，如：
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
26
27
28
29
30
31
32
33
34
35
36
37
38
39
40
| use Illuminate\Support\Facades\RateLimiter;
use Illuminate\Http\Request;
use Illuminate\Cache\RateLimiting\Limit;
public function boot()
{
// 100/IP/24h
RateLimiter::for('limitsec', function (Request $request) {
$key = $_SERVER['REMOTE_ADDR'];
if (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {
$key = $_SERVER['HTTP_X_FORWARDED_FOR'];
}
$key .= $request->route()->uri;
return Limit::perDay(100)->by($key)->response(function () {
return response()->json([
'code' => 500,
'message' => '操作触发速率限制，请稍后再试。',
'data' => "",
]);
});
});
// ocr 50/IP/24h
RateLimiter::for('limitocr', function (Request $request) {
$key = $_SERVER['REMOTE_ADDR'];
if (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {
$key = $_SERVER['HTTP_X_FORWARDED_FOR'];
}
$key .= $request->route()->uri;
return Limit::perDay(50)->by($key)->response(function () {
return response()->json([
'code' => 500,
'message' => '操作触发速率限制，请稍后再试。',
'data' => "",
]);
});
});
parent::boot();
}

在路由中使用：
1
| Route::post('/api/ocr', 'Home\ApiController@ocr')->middleware(['throttle:limitocr']);
