使用jQuery In Post方法发送文件

Question

我无法使用此代码

在jquery中读取文件

// Html代码

< input type="file" id="UploadedImage" name="UploadedImage" accept="image/*">

// JS代码

  var file_data = $("#UploadedImage").prop("files")[0];  
  var form_data = new FormData();        

            form_data.append("fileData", file_data);

                jQuery.ajax({
                    type:'POST',
                    url:Drupal.settings.basePath + 'KycCallBack',
                    data:
                    {
                        id:"SaveKYC",
                        UploadedImage:form_data,

                    },
                    success:function(data)
                    {

                        jQuery(".ajaxLoading").hide();

//我希望在我的API中的php中读取这样的内容

    $UploadedImage = $_FILES["UploadedImage"]["name"];  
    $target_dir = "sites/all/modules/vestigepos/vestigepos/KYCImages/";
    $target_dir = $target_dir . basename( $_FILES["UploadedImage"]["name"]);
    if (move_uploaded_file($_FILES["UploadedImage"]["tmp_name"],     $target_dir)) {
                    echo "File Uploaded ";
                    }
