函数计算提供了丰富类型的触发器，不同种类的触发器事件格式会根据具体情况而有所差异，下面将详细列举各触发器对应的事件格式。

HTTP触发器

通过HTTP触发器和自定义域名访问事件函数时，仅会把请求中的body部分通过event传递到事件函数的handler，数据类型是byte数组。而header和queryparams等其余请求信息会被丢弃，如果用户需要关心请求中除body以外的信息，可以使用Http函数

云原生网关触发器

云原生网关触发器与Http触发器的行为相同，详细请参考上文。

定时触发器

{
    "time": "2025-08-14T02:24:09Z",
    "name": "trigger-name",
    "data": "hello,trigger"
}

Kafka触发器

有两种消息格式：RawData和CloudEvent格式，可在触发器配置里选择。

CloudEvent格式如下：

[
    {
        "id": "eca53463-6baf-4d56-8f86-cbdb748208ed",
        "source": "ctyun.faas.trigger.kafka",
        "specversion": "1.0",
        "type": "kafka:topic:send-message",
        "datacontenttype": "application/json",
        "subject": "kafka-trigger-mqbjvsezbp-dial-test:test-for-faas",
        "time": "2025-08-14T02:04:16Z",
        "data": {
            "headers": {},
            "timestamp": 1747879456,
            "topic": "test-for-faas",
            "partition": 0,
            "offset": 15280,
            "key": "",
            "value": "msg[9]: 154b2a0e-2c3d-4b03-ae9e-c225b5370c3b, ts=2025-08-14 02:04:16"
        }
    }
]

RawData格式是CloudEvent格式的子集，只包含原始kafka消息的信息，消息结构相当于CloudEvent的data字段

[
  {
    "offset" : 15280,
    "partition" : 0,
    "headers" : {},
    "topic" : "test-for-faas",
    "key" : "testkey",
    "timestamp" : 1747879456,
    "value" : "msg[9]: 154b2a0e-2c3d-4b03-ae9e-c225b5370c3b, ts=2025-08-14 02:04:16"
  }
]

RocketMQ触发器

有两种消息格式：RawData和CloudEvent格式，可在触发器配置里选择。

CloudEvent格式如下：

    {
        "id": "21000777109E05EF04B574B8A1DF0001",
        "source": "ctyun.faas.trigger.rocketmq",
        "specversion": "1.0",
        "type": "rocketmq:topic:send-message",
        "datacontenttype": "application/json",
        "subject": ":mq-func-hckzeddbxj-rocket-test:test-for-faas",
        "time": "52025-08-14T16:18:39Z",
        "data": {
            "topic": "test-for-faas",
            "properties": {
                "CLUSTER": "1dafcb4049ba42df96d80b7dd2f99c5e",
                "CONSUME_START_TIME": "1747987057130",
                "KEYS": "webtest",
                "MAX_OFFSET": "2",
                "MIN_OFFSET": "0",
                "TAGS": "1747987057097_0",
                "UNIQ_KEY": "21000777109E05EF04B574B8A1DF0001"
            },
            "data": "WebTestTools_174798gjkS"
        }

    {
        "topic": "test-for-faas",
        "properties": {
