如何使用 prebid.js 处理来自 GOT 的多个广告位

Question

我也从 Adnuntius 迁移到 GPT 并且正在使用 prebid.js 我在每个页面上都需要不同的插槽，当我尝试定义它们时，如果我在每个插槽上都有不同的尺寸，我只会让它们工作。假设我在第一个上使用 970x250 并将第二个更改为 300x250 它会工作.

我认为我的问题出在我定义插槽的地方，或者可能是我们的 adunit？

我希望能够对所有插槽使用相同的大小。 site_level 是我们来自 gpt 的 adunit 名称

var div_sizes_l = [[970, 250], [980, 200], [980, 240]];
var PREBID_TIMEOUT = 1000;
var FAILSAFE_TIMEOUT = 3000;

var adUnits = [
    {
        code: 'div-gpt-ad-Landing_Top',  
        mediaTypes: {
            banner: {
                sizes:  div_sizes_l,
            }
        },
        bids: [
            {
                bidder: 'rubicon',
                params: {
                    accountId: '20562',
                    siteId: '2153438',
                    zoneId: '11258332'
                }
            }
        ]
    },
    //
    {
        code: 'div-gpt-ad-Landing_Middle',
        mediaTypes: {
            banner: {
                sizes:  div_sizes_l,
            }
        },
        bids: [
            {
                bidder: 'rubicon',
                params: {
                    accountId: '20562',
                    siteId: '2153438',
                    zoneId: '11258344'
                }
            },
        ]
    },
];

var googletag = googletag || {};
googletag.cmd = googletag.cmd || [];
googletag.cmd.push(function() {
    googletag.pubads().disableInitialLoad();
});

var pbjs = pbjs || {};
pbjs.que = pbjs.que || [];

pbjs.que.push(function() {
    pbjs.addAdUnits(adUnits);
    pbjs.requestBids({
        bidsBackHandler: initAdserver,
        timeout: PREBID_TIMEOUT
    });
});

function initAdserver() {
    if (pbjs.initAdserverSet) return;
    pbjs.initAdserverSet = true;
    googletag.cmd.push(function() {
        pbjs.que.push(function() {
            pbjs.setTargetingForGPTAsync();
            googletag.pubads().refresh();
        });
    });
}
// in case PBJS doesn't load
setTimeout(function() {
    initAdserver();
}, FAILSAFE_TIMEOUT);

 googletag.cmd = googletag.cmd || [];

 googletag.cmd.push(function() {
    googletag.defineSlot('/21855748559/site_level', 
   div_sizes_l, 
  'div-gpt-ad-Landing_Top').addService(googletag.pubads());
    googletag.pubads().setTargeting('position', 'Landing_Top');

    googletag.pubads().enableSingleRequest();
    googletag.enableServices();
});
googletag.cmd.push(function() {
    googletag.defineSlot('/21855748559/site_level', 
    div_sizes_l, 
   'div-gpt-ad-Landing_Middle').addService(googletag.pubads());
    googletag.pubads().setTargeting('position', 'Landing_Middle');

    googletag.pubads().enableSingleRequest();
    googletag.enableServices();
});

您的预出价代码是正确的，它将能够在两个广告单元的拍卖中为所有尺寸使用该变量。但是，由于您使用的是 Rubicon，这就是出现问题的原因。他们的适配器特别需要一组 adunit 尺寸 ID#，然后才能读取并向您传递正确尺寸的出价响应。 [查看这里查看他们的文档] (http://prebid.org/dev-docs/bidders/rubicon.html)。示例：

{
    bidder: 'rubicon',
    params: {
        accountId: '20562',
        siteId: '2153438',
        zoneId: '11258332',
        sizes: [15, 3, 2]
    }
}

这里还有他们的 sizeMap 供您参考以将正确的尺寸 ID 传递给他们，这是直接从他们的 [适配器源] (https://github.com/prebid/Prebid.js/blob/master/modules/rubiconBidAdapter.js) 中提取的：
