Gmail 联系人/反序列化 json 包含电子邮件的对象

Question

我想获取 gmail 联系人（实际上是电子邮件联系人），所以我在 google 开发者控制台上注册并获取了凭据，然后使用访问令牌获取了联系人。使用范围：

https://www.google.com/m8/feeds/ + https://www.googleapis.com/auth/contacts.readonly

并请求 uri 为：

https://www.google.com/m8/feeds/contacts/default/full?alt=json

这给了我这个 json 结果：

要么我需要一种更好的方法从 gmail 中获取电子邮件联系人，要么我需要一种方法将这个 json 反序列化为 class，我试图通过转换这个 json 来反序列化] 到 C# 但证明不成功。让我知道可以做什么。

Answer 1

解决了我的问题，有时会出现像“$t”这样的实例或其中包含“$”的类似内容，当转换为 C# class 时会导致名称无效。要解决这个问题，请添加 dll 引用 'Newtonsoft.Json' 并使用命名空间作为 'using Newtonsoft.Json' 创建一个 class 并在每个属性中名称变得无效，如下所示；

public string __invalid_name__$t { get; set; }

添加 Json 属性属性，如下所示，并根据您的喜好更改名称：

[JsonProperty("$t")]
public string NameOfMyChoosing { get; set; }
