Swift/Firebase：无法在 Firebase 云函数上发送请求数据

Question

我似乎无法通过请求正文从 Swift iOS 应用向 Firebase 发送标识符。

我的 javascript 代码有效（我在 API 构建器中测试过它）：

exports.numberOfVideos = functions.https.onRequest((request, response) => {
var attributionID = request.body.data.attributionID || "No attributionID found.";
functions.logger.info('[LOG]: request.body has a value of ' + JSON.stringify(request.body), {structuredData: true});
var db = admin.firestore();

db.collection("content").get().then(snapshot => {
    var total = 0;
    snapshot.forEach(doc => {
        if (doc.data().attributionID == attributionID) {
            total++;
        }
        // stuff = stuff.concat(newelement);
    });
    response.send('{"data": {"attributionID": "' + attributionID + '", "numberOfContents": "' + total + '"}}');
    return "";
}).catch(reason => {
    response.send(reason)
})
 });

我的Swift代码看不到传送数据：

static func getContentCount(for obj: Object, completion: @escaping (_ count: Int?) -> Void) {
    let httpsCallable = functions.httpsCallable("numberOfVideos")

//        httpsCallable.setValue("application/json", forKey: "Content-Type")
    httpsCallable.call(["attributionID" : obj.id]) { result, error in
        if let error = error as NSError? {
            if error.domain == FunctionsErrorDomain {
                let code = FunctionsErrorCode(rawValue: error.code)
                let message = error.localizedDescription
                let details = error.userInfo[FunctionsErrorDetailsKey]
                print(error)
            }
        }
        

        if let response = result?.data as? [String: [String: Any]] {
            if let data = response["data"] {
                if let countAsAString = data["numberOfContents"] as? String {
                    let count = Int(countAsAString)
                    if count != nil {
                        completion(count)
                    } else {
                        print("Data is valid but no count found: \(result?.data)")
                        completion(nil)
                    }
                }
            }
        } else {
            print("Data is invalid: \(result?.data)")
            completion(nil)
        }
    }
}

当它在 REST API 测试仪上运行时，正文如下：

POST /numberOfVideos HTTP/1.1
Host: *****************
Content-Type: application/json
Content-Length: 49

{"data":{"attributionID":"biNiaWVtmjUKoTQ1fTZu"}}

如有任何帮助，我们将不胜感激！

已修复。我必须使用 NSDictionary，而不是字典：

NSDictionary(dictionary: ["attributionID" : obj.id])
