我一直在努力保存我从HTTP请求中检索的文件几天了.这是我的代码:

    Parse.Cloud.httpRequest({
    url: "https://ss1.4sqi.net/img/categories_v2/food/vietnamese_88.png",
    success: function(httpImgFile) 
    {
        console.log("httpImgFile: " + String(httpImgFile.buffer));
        var imgFile = new Parse.File("imgFile1.png", httpImgFile.buffer);                                               
        object.set("location", "newYork"); //object is a PFObject retrieved earlier
        object.set("icon1", imgFile);
        object.save(null, {
          success: function(gameScore) {
            response.success("saved object");
          },
          error: function(gameScore, error) {
            response.error("failed to save object");
          }
        });     
    },
    error: function(httpResponse) 
    {
        console.log("unsuccessful http request");
        response.error(responseString);
    }
});

我得到的错误是:
