angular2 json2typescript-jsonConvert.deserializeObject不起作用

问题描述

你好，我是angular 2的新手，我从Google，facebook和linkedin获取用户数据.我正在尝试反序列化对象到我创建的名为UserLogin的实例，但是它不起作用.

hello i am new in angular 2 and i am pulling from google , facebook and linkedin the data of user. i am trying to do deserialize object to instance that i created called UserLogin but it doesn't work.

登录方法:

signIn(provider: string) {
    this.sub = this._auth.login(provider).subscribe(
        (loginDataObj) => {
            console.log(loginDataObj);
            let jsonConvert: JsonConvert = new JsonConvert();
            let user: UserLogin = jsonConvert.deserializeObject(loginDataObj, UserLogin);

            console.log(user.email);
            //user data
            //name, image, uid, provider, uid, email, token (accessToken for Facebook & google, no token for linkedIn), idToken(only for google)
        }
    )
}

UserLogin类:

UserLogin class:

    @JsonObject
export class UserLogins implements IUserLogin{

    @JsonProperty("email", String)
    public email: String;
    @JsonProperty("idToken", String)
    public idToken: String;
    @JsonProperty("image", String)
    public image: String;
    @JsonProperty("name", String)
    public name: String;
    @JsonProperty("provider", String)
    public provider: String;
    @JsonProperty("token", String)
    public token: String;
    @JsonProperty("uid", String)
    public uid: string;

}

当我将console.log记录到数据时，可以正常打印，但是当我尝试反序列化并打印user.email时，则发送未定义的电子邮件

when i do console.log to the data its printed ok but when i am trying to deserialize and printed the user.email its undefined

感谢帮手.

推荐答案

每个变量都需要初始化.我自己才发现的.@JsonProperty("email"，字符串)公开电子邮件:String =";

Each variable needs to be initialized. I just found this out myself. @JsonProperty("email", String) public email: String = "";
