如何在Node.js中进行远程REST调用？ 任何CURL？
在Node.js中 ，除了使用子进程进行CURL调用之外，是否有一种方法可以对远程服务器REST API执行CURL调用并获取返回数据？
我还需要将请求头设置为远程REST调用，以及GET（或POST）中的查询字符串。
我找到了这个：http://blog.nodejitsu.com/jsdom-jquery-in-5-lines-on-nodejs
但它不会以任何方式显示POST查询字符串。
看看http.request
var options = {
host: url,
port: 80,
path: '/resource?id=foo&bar=baz',
method: 'POST'
};
http.request(options, function(res) {
console.log('STATUS: ' + res.statusCode);
console.log('HEADERS: ' + JSON.stringify(res.headers));
res.setEncoding('utf8');
res.on('data', function (chunk) {
console.log('BODY: ' + chunk);
});
}).end();
如何使用请求 - 简化的HTTP客户端。
这里是一个GET：
var request = require('request');
request('http://www.google.com', function (error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body) // Print the google web page.
}
})
OP也想要一个POST：
request.post('http://service.com/upload', {form:{key:'value'}})
