Question

我尝试反序列化我从sendgrid获得的这个json字符串。我使用hakanL的sendgridplus存储库：https://github.com/HakanL/sendgridplus-csharp

[{"email":"ogsasd@gmail.com","Identification":"934224","timestamp":1387734767,"ip":"83.223.255.137","useragent":"Mozilla/5.0 (iPhone; CPU iPhone OS 7_0_3 like Mac OS X) AppleWebKit/537.51.1 (KHTML, like Gecko) Mobile/11B511","category":["ReservationConfirmation"," Online"," Salonkey-86432150"," AppointmentId-132347"," SalonId-223"],"event":"open"}]

以下是我使用的方法：

public static List<EventData> GetEvents(string json)
        {
            // RWM: Deal with v1 and v2 batched Event data.
            if (!json.StartsWith("["))
            {
                json = string.Format("[{0}]", json.Replace("}" + Environment.NewLine + "{", "},{"));
            }

            // RWM: Hack to deal with SendGrid not being able to get their shit together and send well-formed JSON.
            if (!json.EndsWith("]"))
            {
                json += "]";
            }

            _logger.Info("Json returned: " + JsonConvert.DeserializeObject<List<EventData>>(json));

            return JsonConvert.DeserializeObject<List<EventData>>(json);
        }

得到同样的问题，看起来响应有空行。

.TrimEnd()修复了问题，不错的问题＆＃39; sendgridplus-csharp＆＃39;添加相同的修复程序。

Dim jsonData As String = sr.ReadToEnd().TrimEnd()

还修复了SendGridCategoryConverter＆＃39;如果你要在任何地方序列化你的EventData：

//// Left as an exercise to the reader :)

serializer.Serialize(writer, value);

尝试反序列化json字符串时出现JsonReaderException
