node post发送http请求

是发送短信的业务，给了一串url地址

function smsF(phone, params) {
    var post_data = {
        USER: "用户名",
        UPWD "密码",
        PHONE phone,
        CONTENT: params
    }
    var content = qs.stringify(post_data);
    var options = {
        method: 'POST',
        hostname: ''127.0.0.1:8080’,  
        path: '/index/abc',  
        form: content,
        headers: {
            'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
        },
    };
    var req = 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);  
        });  
    });  
    req.on('error', function (e) {  
        console.log('problem with request: ' + e.message);  
    });    
    // write data to request body  
    req.write(content);  
    req.end();  
}
