Question

我正在使用ms图表联系人api并寻找过滤器选项

是否可以过滤电子邮件或商务电话中至少包含一个元素的联系人？

我已经尝试了类似$ filter = emailAddresses / $ count gt 0'

的内容

Answer 1

$ count仅适用于联系人级别，根据this document，电子邮件或商务手机尚不支持$ filter。

作为解决方法，您可以使用c＃/ javascript过滤联系人集合中的结果。例如在c＃：

中

     using (var request = new HttpRequestMessage(HttpMethod.Get, "https://graph.microsoft.com/v1.0/me/contacts"))
                {
                    request.Headers.Add("Authorization", "Bearer " + token);
                    request.Headers.Add("Accept", "application/json;odata.metadata=minimal");

                    using (var response = client.SendAsync(request).Result)
                    {

                        if (response.StatusCode == HttpStatusCode.OK)
                        {
                            var model = JsonConvert.DeserializeObject<RootObject>(response.Content.ReadAsStringAsync().Result);
                            foreach (var item in model.value)
                            {
                                if (item.BusinessPhones.Count>0)
                                {
                                    //you could add this contact to a contact list .
                                }
                            }


                        }

                    }
                }

    public class RootObject
    {

        public List<Value> value { get; set; }
    }

    public class Value
    {
        public string id { get; set; }
        public List<object> BusinessPhones { get; set; }
        public List<object> EmailAddresses { get; set; }
    }
