Question

我想从我的Tumblr博客中获取所有图片，（无限制）

即使我将限制更改为大数字，默认情况下它变成了20张图片，我只是想知道我创建的代码有什么问题，请帮助..提前感谢

请检查上面的小提琴以检查结果。

在Tumblr api docs上，明确指出，对于请求/posts，您只能获得从1到20的限制。

我采用的方法是一个带有offset参数的递归函数。（从下面我删除了一些不起作用的代码/被注释掉了）

function GetImages(offset) {
    var postUrl = tumblrUrl + blogUrl + apiType + '?api_key=' + apiKey + '&limit=20&offset=' + offset;
    $.ajax({
        url: postUrl,
        type: 'get',
        dataType: 'jsonp',
        complete: function(){

        },
        success: function( strData ){

            console.log(strData.response.posts);

            var posts = strData.response.posts;
            $.each(posts, function (i, v) {
                if(typeof v.photos !== 'undefined') {
                    var n = Math.floor(Math.random() * 6);
                    var info = $($.parseHTML(v.caption)).text();
                    tileContainer.append('<li class="item"><div class="tile-img-container"><img src="' + v.photos[0].alt_sizes[2].url + '"></div><div class="tile-info-container"><a class="various fancybox" href="' + v.post_url + '">' + info + '</a></div></li>');
                    //tileContainer.append('<li class="item"><div class="tile-img-container"><img src="' + v.photos[0].alt_sizes[2].url + '"></div><div class="tile-info-container"><a title="' + info + '" class="various fancybox" href="' + v.photos[0].original_size.url + '">' + info + '</a></div></li>');
                }
            });


            $('ul#tiles').on('click', 'li.item', function (e) {
                var href = $(this).find('.tile-info-container').find('a').attr('href');
                $(this).parents('.item').find('.tile-info-container').find('a').trigger('click');
                window.open(href);
                //$(this).find('.tile-info-container').find('a').trigger('click');

            });


            $('ul#tiles').on('click', 'li.item a', function (e) {
                e.preventDefault();
            });

            $('.tile-img-container').on('click', function (e) {
                $(this).parents('.item').find('.tile-info-container').find('a').trigger('click');
                e.preventDefault();
            });

            // actual changed part
            if (typeof offset === "undefined") {
                offset = 0;
            }
            // (to avoid having to load a hundred pages for each time it was tested, there was also this in the if: `offset < 100 &&`)
            if (((offset + 20) < strData.response.total_posts)) {
                GetImages(offset + 20);
            }
        }
    });
}
GetImages(0);
