可否提供复现步骤关于：userInfoBodyString && WeixiaoUserInfoResp

[jayzch]

userInfoBodyString

userInfoBodyString的内容为

{"errcode":0,"errmsg":"OK","weixiao_stu_id":"mmmmm","card_number":"1111111","name":"\u5f20\u7a0b\u6d69","identity_type":1,"data_source":0,"ocode":"1111111"}

public class WeixiaoUserInfoResp {
    @Override
    public String toString() {
        return "WeixiaoUserInfoResp{" +
                "card_number='" + card_number + '\'' +
                '}';
    }

    String card_number;

    public String getCard_number() {
        return card_number;
    }

    public void setCard_number(String card_number) {
        this.card_number = card_number;
    }
}
