最近接第应用宝支付，其中有个地方要去向SDK服务器发送带cookie的请求，不知道什么原因，怎么发都提示{"msg":"missing cookie for request url","ret":-14}，用postman发送也是同样的错误，代码如下：

 var data = {
        appid: 'wxappid',
        appkey: 'wxappkey',
        openid: 'xxxxx',
        openkey: 'xxxxSmlWBcqGjH1u7yO0C4DgTA',
        ts: Math.floor(new Date().getTime() / 1000),
        pf: 'sdfsdfx2584061791528',
        pfkey: 'sdfsdfd',
        zoneid: '1'
    };
  var cookie_val = 'session_id=' + encodeURIComponent(data.openid) + '&session_type=' + encodeURIComponent(data.openkey) +
        '&org_loc=' + encodeURIComponent('/mpay/get_balance_m');
// 用这个data来计算签名啥的一大堆省略
  data.sig = sign;
    var content = qs.stringify(data);
    var options = {
        hostname: 'ysdktest.qq.com',
        port: 443,
        path: '/mpay/get_balance_m',
        method: 'POST',
        headers: {
            'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8',
            'Cookie': cookie_val
        }
    };

    var req = https.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); // 输出 {"msg":"missing cookie for request url","ret":-14}
        })
    });
    req.on('error', function (e) {
        console.log('problem with request: ' + e.message);
    });
    req.write(content);
    req.end();

GET 和POST 都试了 都是同样的返回结果 然后我又用了request模块

  var url = 'https://ysdktest.qq.com/mpay/get_balance_m?' + qs.stringify(data);

    request = request.defaults({jar: true});
    var j = request.jar();
    var cookie = request.cookie(cookie_val);
    j.setCookie(cookie, url);
    request({url: url, jar: j}, function (error, response, body) {
        console.log(body); // {"msg":"missing cookie for request url","ret":-14}
    });
