通過 https.onCall 的 Firebase Cloud 功能

Question

我正在嘗試通過 https.onCall 從 Web 瀏覽器或使用 curl 命令調用 firebase 雲函數。 我用 curl 得到以下響應：

{"error":{"status":"INVALID_ARGUMENT","message":"Bad Request"}}

當我通過瀏覽器嘗試（並在 firebase 上進行身份驗證）時，出現錯誤：域 ...“在 Access-Control-Allow-Origin 標頭中找不到”，

這可能更多地與http跨域請求有關，而不是firebase。 我試圖將 Access-Control-Allow-Origin 標頭設置為“*”，但無濟於事。

由於我試圖讓 https.onCall 工作，我對服務器功能使用了一個超級簡單的方法：

        exports.testClientCall = functions.https.onCall((req, res) => { 
         var jsonObj = {"Founder": "Apple"};
        var json = JSON.stringify(jsonObj);
      response.send(json);
        });

Web 瀏覽器中的客戶端功能是：

    function getDataFromFirebaseFunction() {
    var http = new XMLHttpRequest();
    var url = "https://us-central1-<myproject>.cloudfunctions.net/testClientCall";
    var params = {"hello":"friend" };
    http.open("POST", url, true);
    
    //Send the proper header information along with the request
    http.setRequestHeader("Content-type", "application/json");
    http.setRequestHeader("X-MyHeader", "123");
    http.setRequestHeader("Access-Control-Allow-Origin", "*");
    http.setRequestHeader("Access-Control-Allow-Methods", "POST");
     
    http.onreadystatechange = function() {//Call a function when the state changes.
        if(http.readyState == 4 && http.status == 200) {
            alert(http.responseText);
        }
    }
    http.send(params);
    }

一直在努力通過客戶端執行 Firebase 雲功能。 有什么想法嗎？
