如何向 Microsoft Vision API 发送 ajax 请求



我在这里遵循文档,底部的示例代码如下所示

<!DOCTYPE html>
<html>
<head>
    <title>JSSample</title>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js">    </script>
</head>
<body>
<script type="text/javascript">
    $(function() {
    var params = {
        // Request parameters
        "returnFaceId": "true",
        "returnFaceLandmarks": "false",
        "returnFaceAttributes": "{age}",
    };
    $.ajax({
        url: "https://api.projectoxford.ai/face/v1.0/detect?" + $.param(params),
        beforeSend: function(xhrObj){
            // Request headers
            xhrObj.setRequestHeader("Content-Type","application/json");
            xhrObj.setRequestHeader("Ocp-Apim-Subscription-Key","REDACTED");
        },
        type: "POST",
        // Request body
        data: "http://newsrescue.com/wp-content/uploads/2015/04/happy-person.jpg",
    })
    .done(function(data) {
        alert("success");
    })
    .fail(function() {
        alert("error");
    });
});
</script>
</body>
</html>

但是我一直收到错误代码404找不到资源。谁能告诉我我做错了什么?

使用Postman快速检查显示您得到的参数错误(不是404)。

几件事:

  1. returnFaceAttributes应该是"age"的(而不是"{age}"
  2. data需要一个参数名称

试试这个(检查data更新):

<html>
<head>
<script src="https://code.jquery.com/jquery-2.1.4.js"></script>
    <title>JSSample</title>
</head>
<body>
<script type="text/javascript">
    $(function() {
    var params = {
        // Request parameters
        "returnFaceId": "true",
        "returnFaceLandmarks": "false",
        "returnFaceAttributes": "age",
    };
    $.ajax({
        url: "https://api.projectoxford.ai/face/v1.0/detect?" + $.param(params),
        beforeSend: function(xhrObj){
            // Request headers
            xhrObj.setRequestHeader("Content-Type","application/json");
            xhrObj.setRequestHeader("Ocp-Apim-Subscription-Key","e2c75ad5d44846d590ac7c2dcc2f210e");
        },
        type: "POST",
        // Request body
        data: '{ "url": "http://newsrescue.com/wp-content/uploads/2015/04/happy-person.jpg"}'
    })
    .done(function(data) {
        console.log(data);
        alert("success");
    })
    .fail(function() {
        alert("error");
    });
});
</script>
</body>
</html>

我创建了一个 jsbin 以确保它有效(根据 Microsoft,她是 19.3 岁)。

最后一个重要说明。立即更改您的Ocp-Apim-Subscription-Key密钥!
