JavaScript閱讀應用 - JSON - FaceAPI

我有這個JSON響應，我需要得到這個響應中的一些元素的值。我想要顯示的值是「化妝」的價值，其中有元素，它是，「eyemakeup」&「lipmakeup」我想顯示它在警報/或文本框中。JavaScript閱讀應用 - JSON - FaceAPI

以下是我迄今爲止使用的javascript，它沒有給我正確的值。

<script type="text/javascript"> 
function processImage() { 

    var subscriptionKey = "mysubkey"; 


    var uriBase = "https://westcentralus.api.cognitive.microsoft.com/face/v1.0/detect"; 

    // Request parameters. 
    var params = { 
     "returnFaceId": "true", 
     "returnFaceLandmarks": "false", 
     "returnFaceAttributes": "age,gender,headPose,smile,facialHair,glasses,emotion,hair,makeup,occlusion,accessories,blur,exposure,noise", 
    }; 

    // Display the image. 
    var sourceImageUrl = document.getElementById("inputImage").value; 
    document.querySelector("#sourceImage").src = sourceImageUrl; 

    // Perform the REST API call. 
    $.ajax({ 
     url: uriBase + "?" + $.param(params), 

     // Request headers. 
     beforeSend: function(xhrObj){ 
      xhrObj.setRequestHeader("Content-Type","application/json"); 
      xhrObj.setRequestHeader("Ocp-Apim-Subscription-Key", subscriptionKey); 
     }, 

     type: "POST", 

     // Request body. 
     data: '{"url": ' + '"' + sourceImageUrl + '"}', 
    }) 

    .done(function(data) { 
     // Show formatted JSON on webpage. 
     $("#responseTextArea").val(JSON.stringify(data, null, 2)); 
     $("#demo2").val(this.responseText); 

     var data =[JSON.stringify(data, null, 2)]; 
     var json = JSON.parse(data); 
     alert(json["eyeMakeup"]);  
    }) 
     .fail(function(jqXHR, textStatus, errorThrown) { 
     // Display error message. 
     var errorString = (errorThrown === "") ? "Error. " : errorThrown + " 
    (" + jqXHR.status + "): "; 
     errorString += (jqXHR.responseText === "") ? "" : 
(jQuery.parseJSON(jqXHR.responseText).message) ? 
      jQuery.parseJSON(jqXHR.responseText).message : 
jQuery.parseJSON(jqXHR.responseText).error.message; 
     alert(errorString); 
    }); 
}; 
    </script>

首先添加contentType:"json"您的$就配置，那麼你不需要的數據解析成JSON，因爲它已經JSON類型所以刪除此行。

var data =[JSON.stringify(data, null, 2)];

根據您的JSON你加入到質疑您會收到對象的陣列從第一對象

獲取數據試試這個：

對於eyeMakeup使用：

data[0].faceAttributes.makeup.eyeMakeup

並用於lipMakeup使用

data[0].faceAttributes.makeup.lipMakeup

或者你可以通過你的結果數據環路，如果你想訪問多個對象數據

$.each(data,function(obj,function(){ 
    console.log(obj.faceAttributes.makeup.eyeMakeup); 
    console.log(obj.faceAttributes.makeup.lipMakeup); 
})

$.ajax({ 
    url:'data.php', 
    data:{ 
     'a' : 1, 
     'b': 2 
    }, 
    type:'post', 
    cache:false, 
    dataType:'json', 
    success:function(data) { 
     do something... 
    }, 
    error : function() { 
     do something 
    } 
});

嘗試使用AJAX像上述高達
