    1. wevemob 和 adstard 返回的数据有这样的:

    "creatives": {
    ""cover_url": "https://lh3.googleusercontent.com/YyDDeSsT7sHD-NQcR8l6Rrhki7HSaJ4hmaUzH7ZoXgW4MVafug9zy2T7kFCzKerDt8M"
    }

    一直以为 creatives.cover_url可以取到值,没想到想错了,根本取不出来。
    只能使用 for i,key 使用 creatives[key]可以取到url。

    有这样的(一个数组):

    creatives=[{
    "1200x627": "http://pic.adsoaring.com/creatives/4ce40a1dbc692449bed0970ab3143a7d.JPEG"
    },
    {
    "300x250": "http://pic.adsoaring.com/creatives/b409f7eb250d32b56fb0aefd55eaa798.JPEG"
    },
    {
    "320x480": "http://pic.adsoaring.com/creatives/18ccef98fb963258a8a405d4f1966888.JPEG"
    },
    {
    "320x50": "http://pic.adsoaring.com/creatives/c8f39fc74e5898ad7ad12132269ea28b.JPEG"
    },
    {
    "480x320": "http://pic.adsoaring.com/creatives/9ab865eb0f494ff136f3b49c1a2be1c5.JPEG"
    }]

    还有这样的(数组又嵌套数组):

    creatives=[[{
    "728x90": "https://cloud.hugoffers.com/creatives/100001/110067/1516849277266_156.jpg"
    }],
    {
    "1": {
    "980x120": "https://cloud.hugoffers.com/creatives/100001/110067/1516849277582_317.jpg"
    }
    },
    {
    "2": {
    "930x180": "https://cloud.hugoffers.com/creatives/100001/110067/1516849277274_947.jpg"
    }
    },
    {
    "5": {
    "120x600": "https://cloud.hugoffers.com/creatives/100001/110067/1516849277851_816.jpg"
    }
    },
    {
    "9": {
    "300x50": "https://cloud.hugoffers.com/creatives/100001/110067/1516849279274_397.jpg"
    }
    }]

    我只能说上游太牛掰了,一个api的数据,一个对象可以有各种数据结构。

    1. 为了适应上述网盟奇葩的数据结构,写啦如下的递归函数:
      function loop_creatives(loop_creatives) {
      for (let[i, key]of Object.keys(loop_creatives).entries()) {
      if (typeof(loop_creatives[key]) == 'string')
      tmpdata.images.push(loop_creatives[key]);
      else
      arguments.callee(loop_creatives[key]);
      }
      }

    2. 变体去掉if else语句,如下:
      for (let[i, key]of Object.keys(creatives).entries()) {
      typeof(creatives[key]) == 'string' && tmpdata.images.push(creatives[key]) || print("no");
      }

    3. 如下写法来自最开始的具体写法,目前修改成了错误的(尝试使用小括号表示或语句段,所以错误):

    for (let[i, key]of Object.keys(creatives).entries()) {
    typeof(creatives[key]) == 'string' && tmpdata.images.push(creatives[key]) || (
    for (let[ii, keyi]of Object.keys(creatives[key]).entries()) (
    typeof(creatives[key][keyi]) == 'string' && tmpdata.images.push(creatives[key][keyi]) || (
    for (let[iii, keyii]of Object.keys(creatives[key][keyi]).entries()) {
    typeof(creatives[key][keyi][keyii]) == 'string' && tmpdata.images.push(creatives[key][keyi][keyii]) || console.log("need more for loop");
    }
    )
    )
    )
    }

    1. 曾经用过的写法是try catch,因为一直不敢相信 if(ad.creatives.cover_url)其实从未执行过,因为ad.creatives.cover_url根本没有这个属性:

    /*
    if(ad.creatives.cover_url)
    tmpdata.images.push(ad.creatives.cover_url);
    else {
    console.log(" ad.creatives : " + JSON.stringify(ad.creatives));
    try {
    ad.creatives.forEach(function(item, index) {
    for (let [i, key] of Object.keys(item).entries()) {
    if(typeof(item[key])=='string'){
    tmpdata.images.push(item[key]);
    }
    }});
    } catch (e) {
    console.log("error using wevemob ad.creatives : " + JSON.stringify(ad.creatives));
    }
    };
    */

    1. 还用过如下版本的代码:

    for (let[i, key]of Object.keys(ad.creatives).entries()) {
    if (typeof(ad.creatives[key]) == 'string')
    tmpdata.images.push(ad.creatives[key]);
    else {
    for (let[ii, keyi]of Object.keys(ad.creatives[key]).entries()) {
    if (typeof(ad.creatives[key][keyi]) == 'string')
    tmpdata.images.push(ad.creatives[key][keyi]);
    else {
    for (let[iii, keyii]of Object.keys(ad.creatives[key][keyi]).entries()) {
    if (typeof(ad.creatives[key][keyi][keyii]) == 'string')
    tmpdata.images.push(ad.creatives[key][keyi][keyii]);
    else {
    console.log("need more for loop");
    }
    }
    }
    }
    }
    }

    1. 最后在common.js定义了如下函数:
      function loop_creatives(loop_creatives,creative_array) {
      for (let[i, key]of Object.keys(loop_creatives).entries()) {
      typeof(loop_creatives[key]) == 'string' && creative_array.push(loop_creatives[key]) || arguments.callee(loop_creatives[key],creative_array);
      }
      }

    2. 调用方式为:
      Commons.loop_creatives(ad.creatives,tmpdata.images);

    3. 思考:上面的函数传入了一个数组并操作之,且递归第一个元素。
      我希望这个函数是传入一个对象并基于该对象返回一个数组,而不需要传入一个数组来操作。
      这样,所有的素材对象可以直接调用这个方法来生成了。
