Question

我正在使用Node.js和请求模块。我正在尝试发布请求api（restfull），但它没有正确发送请求。我可以在curl和python的请求模块中工作，但不能在node.js请求模块中工作：

var request = require('request');

token = 'sfgsfsf';

var options = {
    url: 'https://_rest_full_api
    headers: {
        'X-Auth-Token': token
    },
    body: {
        'status' : 'pending'
    },
    json: true,
    method: 'put'
};

function callback(error, response, body) {
    if (!error && response.statusCode == 200) {
        var info = JSON.parse(body);
        console.log(info);
        console.log(info);
    } else {
        console.log(response.statusCode);
        console.log(response.body);
    }
}

request(options, callback);

Answer 1

将json选项设置为true，请求会自动将主体解析为对象。您正在使用以下行重新解析正文：

var info = JSON.parse(body)

当您尝试解析对象时，您会收到该消息：

$ node
> var t = {};
> JSON.parse(t);
SyntaxError: Unexpected token o

Answer 2

var request = require('request');
 function updateClient(postData){
            var clientServerOptions = {
                uri: 'http://'+clientHost+''+clientContext,
                body: JSON.stringify(postData),
                method: 'PUT',
                headers: {
                    'Content-Type': 'application/json'
                }
            }
            request(clientServerOptions, function (error, response) {
                console.log(error,response.body);
                return;
            });
        }

在客户端。然后，

var express = require('express');
var bodyParser = require('body-parser');
var app = express();
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json())

var port = 9000;

app.put('/sample/put/data', function(req, res) {
    console.log('receiving data ...');
    console.log('body is ',req.body);
    res.send(req.body);
});

// start the server
app.listen(port);
console.log('Server started! At http://localhost:' + port);

在服务器端。

Node.js请求模块....使用put在api请求中发送json
