Question

所以我有一个Nodejs服务器，它接收一个JSON对象，然后将它放入变量并通过电子邮件发送内容。这是我的代码：

＆＃13;

app.post('/sendEmail', function(req, res) {
	var answers = req.body.answers;
	var str = JSON.stringify(answers, null, "\t"); // stringify with tabs inserted at each level
	console.log(answers);
	var fromEmail = new helper.Email('ahun...ok.com');
	var toEmail = new helper.Email('ahun...ok.com');
	var subject = 'Survey Completion';
	var content = new helper.Content('text/plain', str);
	
	
	var mail = new helper.Mail(fromEmail, subject, toEmail, content);

	var sg = require('sendgrid')(process.env.SENDGRID_API_KEY);
	var request = sg.emptyRequest({
	  method: 'POST',
	  path: '/v3/mail/send',
	  body: mail.toJSON()
	});
	
	sg.API(request, function (error, response) {
	  if (error) {
	    console.log('Error response received');
	  }
	});
	
	res.send("Success");
	
});

＆＃13;

正如您所看到的，我使用stringify使JSON更漂亮，但它仍然具有所有粗括号和引号以及间距作为JSON。有没有办法以更易读的形式存储JSON？

电子邮件内容如下： var content = new helper.Content('text/plain', str); 因此，可读的JSON需要存储在具有格式等的变量中。

任何帮助将不胜感激。感谢

编辑：这是发送的JSON对象：

＆＃13;

{

"question1": {
	"Reliable": true,
	"Knowledgeable": true,
	"Helpful": true,
	"Courteous": true
},
"question2": {
	"checked": "Extremely Well"
},
"question3": {
	"checked": "Extremely Well"
},
"question4": {
	"checked": 3
},
"fullName": "Test",
"address": "Test",
"city": "Test",
"state": "Test",
"zip": "321",
"areaCode": "321",
"phone": 1234567896,
"call": true,
"lifeInsurance": "Yes",
"brokerage": "Yes",
"bankName": "Regions"
}

＆＃13;

使用上面的JSON对象，我想将其格式化为：

问题1：可靠，知识渊博，乐于助人，彬彬有礼。

问题2：非常好。

问题3：非常好。

问题4：3。

全名：测试。

地址：测试。

...

经纪：是的。

银行名称：地区。

Answer 1

数据只需要一点按摩

＆＃13;

var data = {
    "question1": {
        "Reliable": true,
        "Knowledgeable": false,
        "Helpful": true,
        "Courteous": true
    },
    "question2": {
        "checked": "Extremely Well"
    },
    "question3": {
        "checked": "Extremely Well"
    },
    "question4": {
        "checked": 3
    },
    "fullName": "Test",
    "address": "Test",
    "city": "Test",
    "state": "Test",
    "zip": "321",
    "areaCode": "321",
    "phone": 1234567896,
    "call": true,
    "lifeInsurance": "Yes",
    "brokerage": "Yes",
    "bankName": "Regions"
};

var result = Object.entries(data).reduce((result, [key, value]) => {
    key = key.replace(/([A-Z]|\d+)/g, ' $1').replace(/^(.)/, (unused, p1) => p1.toUpperCase());
    if (!['string', 'number', 'boolean'].includes(typeof value)) {
        value = Object.entries(value).map(([key, value]) => (typeof value == 'boolean') ? (value ? key : undefined) : value).filter(v => v !== undefined).join(',');
    }
    result.push(`${key}: ${value}`);
    return result;
}, []);
console.log(result.join('\n'));

注意：我将其中一个true更改为false以检查逻辑

更简单的答案可能是解析JSON然后将其转储为YAML：

---
question1:
  Reliable: true
  Knowledgeable: true
  Helpful: true
  Courteous: true
question2:
  checked: Extremely Well
question3:
  checked: Extremely Well
question4:
  checked: 3
fullName: Test
address: Test
city: Test
state: Test
zip: '321'
areaCode: '321'
phone: 1234567896
call: true
lifeInsurance: 'Yes'
brokerage: 'Yes'
bankName: Regions

Node.js有几个YAML库，我不记得我喜欢哪个，但我想说我在js-yaml上运气不错。
