将 user_data 发送到 GA4、Google 广告等时使用 sha256 进行哈希处理

Question

tl;dr：城市、地区、邮政编码、国家/地区是否应该有 sha256_ 前缀，我是否应该对它们进行哈希处理？

----详情 我想知道谷歌是否不认为城市、地区和邮政编码是敏感信息，或者文档不完整。从第二个例子来看，我什至不需要对街道地址进行哈希处理。但我相信我应该散列一切...... 【示例中使用smarty】

                gtag('set', 'user_data', {
                    "sha256_email_address": "{hash('sha256', $order_info.email)}",
                    "address": {
                        "sha256_first_name": "{hash('sha256', $order_info.firstname)}",
                        "sha256_last_name": "{hash('sha256', $lastname)}",
                        "sha256_street": "{hash('sha256', $address)}",
                        "sha256_city":"{hash('sha256', $city)}",
                        "sha256_region":"{hash('sha256', $country)}",
                        "sha256_postal_code": "{hash('sha256', $zipcode)}",
                        "sha256_country": "{hash('sha256', $country)}"
                    }
                });

"sha256_city":"{hash('sha256', $city)}",

与

"city":"{hash('sha256', $city)}",

与

"city":"{$city}",

Answer 1

文档显示了这个清晰的示例（在 Node.js 中）：

user_data: {
  sha256_email_address: yourEmailSha256Variable,
  sha256_phone_number: yourPhoneSha256Variable,
  address: {
    sha256_first_name: yourFirstNameSha256Variable,
    sha256_last_name: yourLastNameSha256Variable,
    sha256_street: yourStreetAddressSha256Variable,
    city: yourCityVariable,
    region: yourRegionVariable,
    postal_code: yourPostalCodeVariable,
    country: yourCountryVariable
  }
}

所以你的问题的答案是：

"city":"{$city}"
