如何从相册通过Facebook图表api获取大图片 [英] how to get large pictures from photo album via facebook graph api

问题描述

我正在使用以下代码从用户个人资料中检索所有照片

I am currently using the following code to retrieve all the photos from a user profile

FB.api('/me/albums?fields=id,name', function(response) {
  //console.log(response.data.length);
  for (var i = 0; i < response.data.length; i++) {
    var album = response.data[i];

    FB.api('/' + album.id + '/photos', function(photos) {
      if (photos && photos.data && photos.data.length) {
        for (var j = 0; j < photos.data.length; j++) {
          var photo = photos.data[j];
          // photo.picture contain the link to picture
          var image = document.createElement('img');
          image.src = photo.picture;
          document.body.appendChild(image);
          image.className = "border";

          image.onclick = function() {
            //this.parentNode.removeChild(this);
            document.getElementById(info.id).src = this.src;
            document.getElementById(info.id).style.width = "220px";
            document.getElementById(info.id).style.height = "126px";
          };
        }
      }
    });

  }
});

但是，它返回的照片质量差，基本上就像缩略图。如何检索较大

but, the photos that it returns are of poor quality and are basically like thumbnails.How to retrieve larger photos from the albums.

一般用于个人资料图片我使用？type = large，返回体面的个人资料图片

Generally for profile picture I use ?type=large which returns a decent profile image

但是，如果从相册
的照片中，type = large不起作用，并且还有一种方法可以从zip格式获取照片一旦我指定照片网址，我希望用户能够下载照片。

but the type=large is not working in the case of photos from photo albums and also is there a way to get the photos in zip format from facebook once I specify the photo url as I want users to be able to download the photos.

推荐答案

您需要更改： / p>

You need to change:

image.src = photo.picture;

to：

image.src = photo.source;

源成员是指向完整照片的链接，而不是由图片会员提供的缩略图链接。

The source member is a link to the full photo, rather then a thumbnail link provided by the picture member.
