我收到错误，我想发送图像并从中接收数据。缺少什么？

我还想知道如何创建一个按钮来发送图像/视频和接收信息。

    $(function() {
        var params = {
            // Request parameters
            "returnFaceId": "true",
            "returnFaceLandmarks": "false",
            "returnFaceAttributes": "{string}",
        };

        $.ajax({
            url: "https://westcentralus.api.cognitive.microsoft.com/face/v1.0/detect?" + $.param(params),
            beforeSend: function(xhrObj){
                // Request headers
                xhrObj.setRequestHeader("Content-Type","application/json");
                xhrObj.setRequestHeader("Ocp-Apim-Subscription-Key","<redacted>");

最佳答案

可以找到带有人脸检测功能的完整 JavaScript 代码 here .

To run the sample, perform the following steps:

  1. Copy the following and save it to a file such as detectFaces.html.
  2. Replace the subscriptionKey value with your valid subscription key.
  3. Change the uriBase value to use the location where you obtained your subscription keys.
  4. Drag-and-drop the file into your browser.
  5. Click the Analyze faces button.

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

        // Replace the subscriptionKey string value with your valid subscription key.
        var subscriptionKey = "13hc77781f7e4b19b5fcdd72a8df7156";

        // Replace or verify the region.
        //
        // You must use the same region in your REST API call as you used to obtain your subscription keys.
        // For example, if you obtained your subscription keys from the westus region, replace
        // "westcentralus" in the URI below with "westus".
        //
        // NOTE: Free trial subscription keys are generated in the westcentralus region, so if you are using
        // a free trial subscription key, you should not need to change this region.
        var uriBase = "https://westcentralus.api.cognitive.microsoft.com/face/v1.0/detect";

        // Request parameters.
        var params = {
            "returnFaceId": "true",

            "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){

            type: "POST",

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

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

        .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>
