hoo*_*rus 1 javascript ajax microsoft-cognitive
我正在关注此处的文档，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>
但我不断收到错误代码 404 资源未找到。谁能告诉我我做错了什么？
Postman的快速检查表明您得到了一个错误的参数（不是 404）。
几件事：
returnFaceAttributes应该是"age"（不是"{age}"）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以确保它正常工作（根据微软的说法，她 19.3 岁）。
最后一个重要说明。Ocp-Apim-Subscription-Key立即更换您的钥匙！
