[英]Express: Remove charset=utf-8 from Content-Type "application/json; charset=utf-8"
[英]Unable to Print a JSON Object in Node js with “content-type”: “text/plain; charset=UTF-8”
我正在嘗試使用以下命令在req.body
中打印JSON對象(即req.body
,但是使用JSON.stringify並沒有幫助。 有人可以建議/指導我如何打印此JSON對象req.body
console.log("printing body: "+JSON.stringify(req.body))
console.log("printing body: "+req.body)
console.log("printing headers: "+JSON.stringify(req.headers))
輸出:
printing body: {}
printing body: [object Object]
printing headers: {
"x-amz-sns-message-type": "SubscriptionConfirmation",
"x-amz-sns-message-id": "3dd623ert-7203-4e12-bf11-36589f9dce65",
"x-amz-sns-topic-arn": "arn:aws:sns:us-west-2:33030356879323:testTopic10",
"content-length": "1520",
"content-type": "text/plain; charset=UTF-8",
"host": "example.com",
"connection": "Keep-Alive",
"user-agent": "Amazon Simple Notification Service Agent",
"accept-encoding": "gzip,deflate"
}
解析Amazon SNS給出的JSON對象的准則:
在步驟1:該點2 文件其通知
使用JSON解析器來處理將轉義的控制字符表示形式轉換回其ASCII字符值(例如,將\\ n轉換為換行符)。 您可以使用現有的JSON解析器,例如Jackson JSON Processor( http://wiki.fasterxml.com/JacksonHome ),也可以編寫自己的解析器。
編輯1:
您可能會看到打印的標題,它們具有content-type": "text/plain; charset=UTF-8
content-type": "text/plain; charset=UTF-8
,這可能是bodyparser.json()
無法工作並且我們無法使用JSON.stringify()
編輯2
這是我的身體解析代碼。
var bodyParser = require('body-parser');
app.use(bodyParser.json()); // Used to parse the JSON request
app.use(bodyParser.urlencoded({ extended: true }));

JSON.stringify()確實打印出了對象。 該對象只是空的,即{}。
