利用 PPS 改进广告系列
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
您可以在广告请求中以发布商提供的信号 (PPS) 的形式发送受众群体和情境数据。借助 PPS，您可以通过使用标准类目将您的受众群体特征传达给所有交易类型的出价方，从而利用用户数据提高程序化变现能力，而无需分享用户标识符。受众群体特征可能包括行为数据和兴趣数据（IAB 受众群体类目 1.1），以及情境数据（IAB 内容类目 2.2）。您还可以发送由 Google 定义的发布商提供的结构化信号，并允许发送其他信号。
构建用户信号 JSON
在顶级，创建一个包含单个键值对的 JSON 对象。键应为 PublisherProvidedTaxonomySignals，其值应为对象数组。数组中的每个对象都应包含 2 个键值对：
构建结构化信号数组
对于结构化信号，请添加 PublisherProvidedStructuredSignals 键，并将其值设为对象数组。根据以下信号键值对列表构建对象：

请参阅以下示例，其中对分类信号使用 IAB_AUDIENCE_1_1 和 IAB_CONTENT_2_2，并且包含结构化信号。
const userSignals = {
"PublisherProvidedTaxonomySignals": [{
"taxonomy": "IAB_AUDIENCE_1_1",
"values": ["6", "284"]
// '6' = 'Demographic | Age Range | 30-34'
// '284' = 'Interest | Business and Finance | Mergers and Acquisitions'
},
{
"taxonomy": "IAB_CONTENT_2_2",
"values": ["49", "138"]
// '49' = 'Books and Literature | Poetry'
// '138' = 'Education | College Education | College Planning'
}],
"PublisherProvidedStructuredSignals": [{
"type": "audio_feed",
"single_value": "af_1",
},
{
"type": "delivery",
"values": ["cd_1", "cd_3"],
},
],
};
如需通过 IMAStreamRequest 发送 PPS，请按以下步骤操作：
let userSignals = """
{
"PublisherProvidedTaxonomySignals": [
{
"taxonomy": "IAB_AUDIENCE_1_1",
"values": [
"1",
"284"
]
}
],
}
"""
let base64Signals = Data(userSignals.utf8).base64EncodedString()
var encodedSignals = base64Signals.replacingOccurrences(of: "+", with: "%2B")
encodedSignals = encodedSignals.replacingOccurrences(of: "/", with: "%2F")
encodedSignals = encodedSignals.replacingOccurrences(of: "=", with: "%3D")
streamRequest.adTagParameters = { "ppsj" : encodedSignals}
