我正在搜索解决方案,可以在Google DFP广告管理系统中自定义广告素材中扩展SafeFrame自定义广告,这有可能吗?

答案 0 :(得分:5)

有两种可能的解决方案:

1)使用SafeFrame API

的优点:

  • 你可以使用它"开箱即用"
  • 您可以在任何网站上使用它,不需要网站上的自定义代码
  • 使用安全
缺点:

  • 仅限于填写网站的可见区域
  • 需要等待,直到广告单元对用户可见

2)使用window.postMessage() javascript方法

编写您自己的API代码

缺点:

  • 您需要在网站上添加自定义代码
  • 如果您使用某些第三方广告
  • ,则可能构成威胁

的优点:

  • 您可以通过广告
  • 为您的网站做几乎所有事情

1)使用SafeFrame API

此API易于使用,您可以在其中查看一些示例 GPT Safeframe preview tool

首先,您需要在网站的<head>

更新DFP广告管理系统初始化脚本
var pageConfig = {
    allowOverlayExpansion: true,
    allowPushExpansion: true,
    sandbox: true
};
googletag.pubads().setSafeFrameConfig(pageConfig);

这样可以在您的网站上展开SafeFrame广告。更多关于这一点     Control SafeFrame Container behavior through GPT

现在,您可以创建自定义广告素材并在网站上将其作为SafeFrame投放。这是我的一个例子。这个例子可以等待&#34;利用它可见,然后将扩展到SafeFrame内的<div id="container">高度:

<div id="container">
    some lines to make container height<br>
    line<br>
    line<br>
    line<br>
    line<br>
    line<br>
    line<br>
    line<br>
    line<br>
    line<br>
    line<br>
    line<br>
    line<br>
    line<br>
    line<br>
    line<br>
    line<br>
    line<br>
</div>

<script>
    // global expanded indicator variable, because API don't have any
    var expanded = false;
    function expand() {
        var self= $sf.ext.geom().self;
        var config = {
            push: true, // we want to push expanded content
            b: 0
        };

        var el = document.getElementById('container');
        var containerHeight = el.offsetHeight;

        // get height from bottom, that need to be expanded
        var expandBottom = containerHeight - self.h;

        // if container is whole inside a SafeFrame, it will not expand
        if(expandBottom < 0) return;

        config.b = expandBottom;
        $sf.ext.expand(config);
    }

    function expandDelayed(forceExpand) {
        // expand will run just once, or you can force it to run again
        // but collapse first is needed
        if(expanded && forceExpand || !expanded) {
            $sf.ext.collapse();
            expanded = false;
            // there must be some timeout, because .collapse(); method is deplayed somehow
            setTimeout(expand, 0);
        }
    }

    $sf.ext.register(160, 150, function(status, data) {
        // this code will do whole magic of "waiting" for right moment
        if (status === 'geom-update') {
            expandDelayed();
        }

        // change global expanded status
        if (status === 'expanded') {
            expanded = true;
        }
    });

    // init
    expandDelayed();
</script>

2。使用window.postMessage() javascript方法

编写您自己的API代码

首先,您需要将此代码放入您网站<head>的DFP初始化脚本中。此代码会将#hash-tag的广告位ID添加到<iframe> src,以便您可以从广告素材内部获取。

googletag.pubads().addEventListener('slotRenderEnded', function (event) {
    var containerId = event.slot.getSlotElementId();
    var containerEl = document.getElementById(containerId);

    if (containerEl === null) return;

    var iframeEl = containerEl.querySelectorAll('iframe')[0];

    // it's delayed by 10 milliseconds, because iframe is not yet fully rendered
    // and limited to max to 10 seconds to wait 
    var timeoutFunction = function () {
        var src = "#" + containerId;
        // `src` attribute is null, when iframe is FriendlyIframe, and
        // when it's present, then it's SafeFrame
        if (iframeEl.getAttribute('src') !== null) {
            src = iframeEl.getAttribute('src').replace(/#.*/, "") + src;
        } else {
            var name = iframeEl.getAttribute('name') + "#" + containerId;
            iframeEl.setAttribute('name', name);
        }
        iframeEl.setAttribute('src', src);
    };
    setTimeout(timeoutFunction, 10);
});

其次,您需要将此代码添加到您的网站,最好将其作为单独的.js文件添加。

function onMessageReceivedGetStyle(e) {

    // this will filter just setStyle commands from correct origin
    if (
        !(e.origin === 'http://tpc.googlesyndication.com' || e.origin === 'https://tpc.googlesyndication.com') ||
        typeof e.data !== 'object' ||
        typeof e.data.id !== 'string' ||
        e.data.cmd !== 'setStyle' ||
        typeof e.data.params !== 'object'
    ) {
        return;
    }

    // remove # character from id, we don't use jquery
    var elementId = e.data.id.replace(/#/, "");

    var wrapperEl = document.getElementById(elementId);
    if (wrapperEl === null) {
        return;
    }

    var elements = [wrapperEl];
    // you can target child elements too with query parameter
    if (typeof e.data.query === 'string' && e.data.query) {
        elements = wrapperEl.querySelectorAll(e.data.query);
    }

    elements.forEach(function (element) {
        Object.keys(e.data.params).forEach(function (param) {
            element.style[param] = e.data.params[param];
        });
    });

}

if (window.addEventListener) {
    addEventListener('message', onMessageReceivedGetStyle, false);
}
else {
    if (window.attachEvent) {
        attachEvent('onmessage', onMessageReceivedGetStyle);
    }
    else {
        window.onmessage = onMessageReceivedGetStyle;
    }
}

第三件事是DFP中自定义广告素材类型中的自定义代码。这是一个例子,类似于 第一个例子,但是这里这个脚本可以等到加载所有内容和图像然后扩展/缩小你的 带有广告素材的iframe:

<div id="container">
    <a href="#" target="_blank">
        <img src="%%FILE:JPG1%%">
    </a>
    <a href="#" target="_blank">
        <img src="%%FILE:JPG2%%">
    </a>
</div>

<style>
    a {
        display: block;
        margin-bottom: .5em;
    }
    img {
        display: block;
        max-width: 100%;
    }
    *:last-child {
        margin-bottom: 0;
    }
</style>

<script>
    var container = document.getElementById('container');

    function resizeOutsideSafeFrame() {
        if (!window.top.postMessage) {
            return false;
        }

        // get ID of your Ad unit <div> with this creative 
        var divGptAdId = '%%PATTERN:url%%';

        if (divGptAdId.indexOf('#') !== -1) {
            divGptAdId = divGptAdId.split('#')[1];
        } else {
            divGptAdId = window.location.hash;
        }

        if(!divGptAdId) {            
            if (window.name.indexOf('#') !== -1) {               
                divGptAdId = window.name.split('#')[1];
            }
        }

        if(!divGptAdId) {
            return;
        }

        // set with to fullwidth, and height to height of container inside creative
        var width = '100%';
        var height = container.offsetHeight + 'px';

        // send our request to website
        window.top.postMessage({
            cmd: 'setStyle',
            id: divGptAdId,
            query: 'div, iframe', // we want to target child div and iframe and don't change container styles
            params: {
                display: 'block',
                height: height,
                width: width
            }
        }, '*');
    }

    document.onreadystatechange = function () {
        // resize iframe when all is loaded
        if (document.readyState == "complete") {
            resizeOutsideSafeFrame();
        }
    };

    // first resize must occur little bit later 
    setTimeout(resizeOutsideSafeFrame, 100);
</script>

这就是全部。如果您想从iframe内部更改网站上的任何内容,您可以在自己的网站上编写自己的cmd代码 网站并从iframe内部调用此命令。

编辑1: 现在注意到,var divGptAdId = '%%PATTERN:url%%;不会以#hash方式在页面上返回div的正确ID,所以现在需要给他一个正确的容器div id更改:

if(!divGptAdId) {
    return;
}

if(!divGptAdId) { 
    divGptAdId = 'div-gpt-ad-container-div-id-1';
}

答案 1 :(得分:0)

我无法找到任何可靠的文档,所以PayteR的例子对我帮助很大!我不得不使用新的维度来让广告以正确的方式扩展。

以下是我从PayteR的例子中创建的一些示例代码:

/* Main object for namespacing */
var Ad = function(obj) {};

/* 
  Register your ad with the dimensions of the current ad.
  - This is basically an event handler for the the ad frame.
  - 728 initial ad width
  - 90 initial ad height
*/
Ad.prototype.registerExpand = function() {
  $sf.ext.register(728, 90, function(status, data){});
};

/* Expand function to be called on click or load */
Ad.prototype.expandAd = function() {

  /* Get the current geometry of your ad */
  var self = $sf.ext.geom().self;

  /* 
    Set the new geometry
    - Increase height 315 pixels
    - Expand downward by setting the bottom to the new height minus the current height
  */
  $sf.ext.expand({
    h: 315,
    b: 315 - self.h
  });
};


/* Intialize, register, and expand */
var ad = new Ad();
ad.registerExpand();
ad.expandAd();
