我需要创建一个包含对象数组、字符串和数字的验证器。
下面是我发现的一个类似的问题：：Class-validator - validate array of objects
下面是应该如何过滤数据......这意味着这些是我希望从请求正文中提取的好参数

{
"call_transfers": [
  {"bid":33,"bid_id":"1239dasdj8","carrier":"Jimmies pizza", "qualification_duration":222},
  {"bid":28,"bid_id":"3234sdfJIA","carrier":"Krusty crabs", "qualification_duration":22},
  {"bid":19,"bid_id":"9anHXawefa","carrier":"Bikiny bottom", "qualification_duration":33},
        ],
"ping_id": "adi2837dasdjc8",
"time" : 0.123      
}

我创建以下请求来测试类验证器是否按预期工作：

{
"name" : "Juan",
"email": "jcasdasda@gmail.com",
"token" : "1oap8X8ase@#*&",
"call_transfers": [
    {"bid":33,"bid_id":"1239dasdj8","carrier":"Jimmies pizza", "qualification_duration":222, "fakeParam":123},
    {"bid":28,"bid_id":"3234sdfJIA","carrier":"Krusty crabs", "qualification_duration":22, "fakeParam":123 },
    {"bid":19,"bid_id":"9anHXawefa","carrier":"Bikiny bottom", "qualification_duration":33, "fakeParam":123}
    ],
"ping_id": "adi2837dasdjc8",
"time" : 0.123,
"authParameters": [{"id":123,"type":"user","value":"chocolates"}]
}

但是，我无法正确过滤所需的参数！
这是我正在使用的控制器逻辑：

setFlagsOnBid(
        @Body('call_transfers') call_transfers: MediaAlphaResponseItem,
        @Body('ping_id') ping_id: MediaAlphaResponseItem,
        @Body('time') time: MediaAlphaResponseItem,
         
        ){
        const filteredData = { call_transfers , ping_id , time };
        return filteredData;
    
    }

这是我正在使用的类验证：

export class MediaAlphaResponseItem {
    @ValidateNested({ each: true })
    @Type(() => MediaAlphaCallTransferItem)
    call_transfers: MediaAlphaCallTransferItem[];

    @IsString()
    ping_id:string;

    @IsNumber()
    time:number;

}

 class MediaAlphaCallTransferItem {

    @IsNumber()
    bid:number;

    @IsString()
    bid_id:string;

    @IsString()
    carrier:string;

    @IsNumber()
    qualification_duration:number;
}

这是postman x1c 0d1x中的输出
