节点并表达发送格式化的json [英] node and express send json formatted

问题描述

我正在尝试通过express发送格式化的json.

I'm trying to send formatted json with express.

这是我的代码:

var app = express();

app.get('/', function (req, res) {
  users.find({}).toArray(function(err, results){
    // I have try both
    res.send(JSON.stringify(results, null, 4));
    // OR
    res.json(results);
  });
});

我在浏览器中获取了json，但这是一个字符串.如何发送它以便它在浏览器中可读?

I get the json in my browser but it's a string. How can I send it so it's readable in the browser?

推荐答案

您将必须像这样将Content-Type设置为application/json

You're going to have to set the Content-Type to application/json like this

app.get('/', function (req, res) {
    users.find({}).toArray(function(err, results){
        res.header("Content-Type",'application/json');
        res.send(JSON.stringify(results, null, 4));
  });
});
