c# - 在 .net/c# 中调用 Marketo Rest Api 的示例代码

Question

有没有人有从 .net/C# 调用 Marketo Rest API 的示例。

我对 oauth 身份验证特别感兴趣。 http://developers.marketo.com/documentation/rest/authentication/

我计划将此端点称为 http://developers.marketo.com/documentation/rest/get-multiple-leads-by-list-id/

我在互联网上找不到任何例子。

我能够编写用于调用 Marketo Rest API 并执行 OAuth 的解决方案。下面是一个操作方法 下面的代码显示了基础知识，但需要清理、日志记录和错误处理才能实现生产价值。

您需要获取 Marketo 实例的 Rest api URL。为此，请登录 marketo，然后导航到 Admin\Integration\Web Services，然后使用 Rest API 部分中的 URL。

您需要从 marketo 获取您的用户 ID 和密码 - 导航到 Admin\Integration\Launch Pont。查看您的 Rest Service 的详细信息以获取 id 和 secret。如果您没有服务，请按照以下说明操作http://developers.marketo.com/documentation/rest/custom-service/。

最后，您需要您的列表 ID 来获取您想要获取的潜在客户列表。您可以通过导航到您的列表并从 url 中复制 id 的数字部分来获取此信息。示例：https ://XXXXX.marketo.com/#ST1194B2 —> 列表 ID = 1194

        private void GetListLeads()
    {
        string token = GetToken().Result;

        string listID = "XXXX";  // Get from Marketo UI
        LeadListResponse leadListResponse = GetListItems(token, listID).Result;
        //TODO:  do something with your list of leads

    }
    private async Task<string> GetToken()
    {
        string clientID = "XXXXXX"; // Get from Marketo UI
        string clientSecret = "XXXXXX"; // Get from Marketo UI

        string url = String.Format("https://XXXXXX.mktorest.com/identity/oauth/token?grant_type=client_credentials&client_id={0}&client_secret={1}",clientID, clientSecret ); // Get from Marketo UI
        var fullUri = new Uri(url, UriKind.Absolute);

        TokenResponse tokenResponse = new TokenResponse();
        using (var client = new HttpClient())
        {
            HttpResponseMessage response = await client.GetAsync(fullUri);

            if (response.IsSuccessStatusCode)
            {
                tokenResponse = await response.Content.ReadAsAsync<TokenResponse>();
            }
            else
            {
                if (response.StatusCode == HttpStatusCode.Forbidden)
                    throw new AuthenticationException("Invalid username/password combination.");
                else
                    throw new ApplicationException("Not able to get token"); 
            }
        }

        return tokenResponse.access_token;
    }

    private async Task<LeadListResponse> GetListItems(string token, string listID)
    {

        string url = String.Format("https://XXXXXX.mktorest.com/rest/v1/list/{0}/leads.json?access_token={1}", listID, token);// Get from Marketo UI
        var fullUri = new Uri(url, UriKind.Absolute);

        LeadListResponse leadListResponse = new LeadListResponse();
        using (var client = new HttpClient())
        {
            HttpResponseMessage response = await client.GetAsync(fullUri);

            if (response.IsSuccessStatusCode)
            {
                leadListResponse = await response.Content.ReadAsAsync<LeadListResponse>();
            }
            else
            {
                if (response.StatusCode == HttpStatusCode.Forbidden)
                    throw new AuthenticationException("Invalid username/password combination.");
                else
                    throw new ApplicationException("Not able to get token");
            }
        }

        return leadListResponse;
    }


    private class TokenResponse
    {
        public string access_token { get; set; }
        public int expires_in { get; set; }
    }

    private class LeadListResponse
    {
        public string requestId { get; set; }
        public bool success { get; set; }
        public string nextPageToken { get; set; }
        public Lead[] result { get; set; }
    }

    private class Lead
    {
        public int id { get; set; }
        public DateTime updatedAt { get; set; }
        public string lastName { get; set; }
        public string email { get; set; }
        public DateTime datecreatedAt { get; set; }
        public string firstName { get; set; }
    }

老问题，只是希望能帮助下一个从谷歌搜索到这里的人:-)

在发这篇文章的时候，这个页面可能还没有，但现在有一个很好的页面，里面有几种语言的例子。该页面位于 http://developers.marketo.com/documentation/rest/get-multiple-leads-by-list-id
