Django Celery 使用 JS 微服務創建任務

Question

您好，我有一個運行 celery 的 Django 應用程序，我正在嘗試使用 JS 中的微服務將任務添加到隊列中。 當我通過 Django 將任務添加到 AWS SQS 時，一切正常，但是當我使用 JS 時出現此錯誤：

[2021-01-05 19:39:55,982: WARNING/MainProcess] Received and deleted unknown message.  Wrong destination?!?

The full contents of the message body was: body: '{"expires":null,"utc":true,"args":[5456,2878],"chord":null,"callbacks":null,"errbacks":null,"taskset":null,"id":"1a361c85-2209-4ffa-95c2-ee2e4855155e","retries":0,"task":"config.celery.debug_task","timelimit":[null,null],"eta":null,"kwargs":{}}' (244b)

我正在使用此代碼發送消息：

let taskId = uuidv4();
let result = {
    "expires": null,
    "utc": true,
    "args": [5456, 2878],
    "chord": null,
    "callbacks": null,
    "errbacks": null,
    "taskset": null,
    "id": taskId,
    "retries": 0,
    "task": "config.celery.debug_task",
    "timelimit": [null, null],
    "eta": null,
    "kwargs": {}
}

const client = new SQSClient({
    region: "eu-west-3",
    credentialDefaultProvider: myCredentialProvider
});

const send = new SendMessageCommand({
    // use wrangler secrets to provide this global variable
    QueueUrl: "SQS_QUEUE_URL_HERE",
    MessageBody: Buffer.from(JSON.stringify(result)).toString("base64")
});

let resultSQS = client.send(send);

我調試了 django 任務有效負載來復制它，所以我發送了它需要的相同數據，但收到了這個錯誤。 任何人都知道我是否遺漏了什么？

謝謝

我解決了這個問題，MessageBody 是錯誤的。 這是解決方案

let taskId = uuidv4();
    let body = [[{"hello": "world from JS", "success": true}], {}, {"callbacks": null, "errbacks": null, "chain": null, "chord": null}]

    let properties = {
        "correlation_id": taskId,
        "reply_to": "5480744c-f3ca-3e3f-9403-445fa5b865e1",
        "delivery_mode": 2,
        "delivery_info": {
            "exchange": "",
            "routing_key": "default"
        },
        "priority": 0,
        "body_encoding": "base64",
        "delivery_tag": uuidv4()
    }


    let headers = {
        "lang": "py",
        "task": "config.celery.debug_task",
        "id": taskId,
        "shadow": null,
        "eta": null,
        "expires": null,
        "group": null,
        "retries": 0,
        "timelimit": [null, null],
        "root_id": taskId,
        "parent_id": null,
        "argsrepr": "({'hello': 'wolrd', 'success': True},)",
        "kwargsrepr": "{}",
        "origin": "gen21089@Marcoss-MacBook-Pro.local"
    }


    let payload = {
        "body": Buffer.from(JSON.stringify(body)).toString("base64"),
        "content-encoding": "utf-8",
        "content-type": "application/json",
        "headers": headers,
        "properties": properties
    }


    let encodedPayload = Buffer.from(JSON.stringify(payload)).toString("base64")

    const client = new SQSClient({
        region: "eu-west-3",
        credentialDefaultProvider: myCredentialProvider
    });

    const sendData = new SendMessageCommand({
        // use wrangler secrets to provide this global variable
        QueueUrl: "URL",
        MessageBody: encodedPayload
    });

    let data = await client.send(sendData);

因此，base64 中的有效負載包含一個“主體”，該“主體”也在 base64 中，以及 Celery 讀取以定位任務的標頭。
