c# - 如何将所有事务模板从一个 SendGrid 帐户迁移到另一个帐户？

Question

给定一个大型的 SendGrid 模板库，如何一键将它们移动到不同的 SendGrid 帐户，比如测试环境？

Answer 1

似乎不可能开箱即用。以下 C# 代码将通过 API 完成工作。

代码使用以下块：NewtonSoft Json.NET、SendGrid API 客户端。

一大警告：迁移后模板 ID 会有所不同。似乎不是保存它们的方法。

    public ActionResult MigrateSendGridTemplates() {

        //https://sendgrid.com/docs/API_Reference/Web_API_v3/Transactional_Templates/templates.html
        //https://sendgrid.com/docs/API_Reference/Web_API_v3/Transactional_Templates/versions.html

        var fromClient = new SendGridClient("full access api key"); //full access key
        var toClient = new SendGridClient("full access api key"); //full access key - assume blank slate

        //fetch all existing templates

        var templatesRaw = fromClient.RequestAsync(SendGridClient.Method.GET, null, null, "templates").Result;

        var templates = templatesRaw.DeserializeResponseBody(templatesRaw.Body);

        var templatesEnumerable = ((IEnumerable)templates.First().Value).Cast<dynamic>().Reverse();

        foreach (var template in templatesEnumerable)
        {
            //fetch template with versions attached

            var templateWithVerisonRaw = fromClient.RequestAsync(SendGridClient.Method.GET, null, null, $"templates/{template.id}").Result;

            var templateWithVersion = templateWithVerisonRaw.DeserializeResponseBody(templateWithVerisonRaw.Body);

            //create template on the new account

            var templateNewRaw = toClient.RequestAsync(SendGridClient.Method.POST, templateWithVerisonRaw.Body.ReadAsStringAsync().Result, null, "templates").Result;

            var activeVersion = ((IEnumerable)templateWithVersion["versions"]).Cast<dynamic>().Where(v => v.active).SingleOrDefault();

            if (activeVersion == null)
                continue; //this template does not have any versions to migrate

            //create template version on new account

            var templateNewId = templateNewRaw.DeserializeResponseBody(templateNewRaw.Body)["id"];

            var templateSerialized = JsonConvert.SerializeObject(activeVersion, Formatting.None);

            var templateVersionNewRaw = toClient.RequestAsync(SendGridClient.Method.POST, templateSerialized, null, $"templates/{templateNewId}/versions").Result;
        }

        return Content($"Processed {templatesEnumerable.Count()} templates.");
    }

由此得出的结论是，如果您希望您的代码跨不同的 sendgrid 帐户工作，您的代码不应依赖模板 ID。相反，您可以构建一个查找字典并通过其友好名称引用您的模板，如下所示：

public static Dictionary<string, string> GetSendGridTemplates()
{
    var templatesRaw = Persistent.ConfiguredSendGridClient.RequestAsync(SendGridClient.Method.GET, null, null, "templates").Result;

    var templates = templatesRaw.DeserializeResponseBody(templatesRaw.Body);

    var templatesEnumerable = ((IEnumerable)templates.First().Value).Cast<dynamic>();

    var results = new Dictionary<string, string>();

    foreach (dynamic template in templatesEnumerable)
    {
        var activeVersion = ((IEnumerable)template.versions).Cast<dynamic>().Where(v => v.active).SingleOrDefault();

        if (activeVersion == null)
            continue; //skip this one

        results.Add((string)activeVersion.name, (string)template.id);
    }

    return results;
}
