javascript - 使用 node.js 读写 vcard

Question

我正在尝试为 vcard 创建和读取两者，在 googleng 了一段时间后没有找到合适的例子，是否有任何 vcard 创建者/阅读器可以开始，

我正在尝试这个 https://www.npmjs.org/package/vcard

我的代码

app.get('/',function(req,res){
    //https://github.com/Fusselwurm/vcard-js/commit/dafd17ffd226c6170849be82e9c5dae94e23b8f0
    card.readFile("./public/sample.vcf", function(err, json1) {
        if(err){  
            console.log("vcard err "+err);
            res.json(util.inspect(json1));
            }
        else
            {
            console.log("vcard json "+json1);
            console.log("vcard json "+util.inspect(json1));
            res.json(util.inspect(json1));
            }


    });
});

示例.vcf文件

日志输出:它仅适用于 sample.vcf 中的 1 个 vcard 数据，但是当它包含更多数据时，它就会出错IEvCard 数据无效:缺少一个或多个必需元素(VERSION 和 FN)

Answer 1

我认为这里有几个问题:

1. 您正在使用的 vcard 库尚未完成
2. 您使用的 vcard 格式不正确

改为查看 vcardparser 库。

var vcardparser = require('vcardparser');

vcardparser.parseFile("./sample.vcf", function(err, json) {
    if(err)
        return console.log(err);
    console.log(json);
});

这是一个示例电子名片:

vcardparser 的输出
