自定义视觉预测（ClassifyImageUrl）错误

Question

我有一个网站，我想在通过点击按钮后使用Azure Custom Vision在经过训练的模型上显示测试图像的结果。

示例我想通过Shark image对其进行分类，并获得具有最高概率的输出标签。

我只是熟悉JavaScript / AJAX，所以我做了这段代码。

    <script>
        $(document).ready(function(){
            $("#yalla").click(function(){
                $.ajax({
                        url: "https://westeurope.api.cognitive.microsoft.com/customvision/v3.0/Prediction/MyPredictionKey/classify/iterations/Classify%20Iteration/url",
                        beforeSend: function(xhrObj){
                                // Request headers
                                xhrObj.setRequestHeader("Prediction-Key","MyPredictionKey");
                                xhrObj.setRequestHeader("Content-Type","application/json");
                        },
                        type: "POST",
                        // Request body
                        data: {"Url": "https://i.imgsafe.org/66/66f4494ce5.jpeg"},
                })
                .done(function(data) {
                        alert("success");
                })
                .fail(function() {
                       //THIS WHAT CODE RESULTS IN
                        alert("Error");
                });
            });
        });
        </script>

但如果有帮助，这也可以在Azure API Console中使用。

POST https://westeurope.api.cognitive.microsoft.com/customvision/v3.0/Prediction/MyPredictionKey/classify/iterations/Classify%20Iteration/url HTTP/1.1
Host: westeurope.api.cognitive.microsoft.com
Prediction-Key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Content-Type: application/json

{
  "url": "https://i.imgsafe.org/66/66f4494ce5.jpeg"
}

可以帮忙吗？
