Javascript 什么是res.writehead和res.write的hapi等价物？

我正在使用ccavenue npm模块将支付网关集成到我的网站中。 该模块的问题在于，它使用

res.write

和

res.writehead

，而传递给模块的

res

变量是由hapi生成的，因此产生错误。那么，hapi与

res.writehead

和

res.write

的等价物是什么呢

这是我的hapi代码：

var ccavenue = require('ccavenue');

ccavenue.setMerchant("******");
ccavenue.setWorkingKey("*******************");
ccavenue.setRedirectUrl("/redirect-url");


module.exports = function(plugin, options, next) {

    plugin.route({
        method: 'GET',
        path: '/checkout',
        handler: function(request, reply) {
            var param = {
                billing_cust_address: 'Bangalore',
                billing_cust_name: 'Nitish Kumar'
            };
        ccavenue.setOrderId("8981455644");
        ccavenue.setOrderAmount("1000");
        ccavenue.setOtherParams(param);
        ccavenue.makePayment(reply);
        }
    });

}

这是模块功能：

function makePayment(res) {
    var errors = helper.checkRequiredField(config);
    if(errors.length > 0) {
        throw new Error(errors);    
    }

    var Checksum = helper.getCheckSum(config.merchantId, config.orderAmount, config.orderId, config.redirectUrl, config.workingKey); //This function is to verify 

    var body = "<form method='post' name='checkout' id='checkout' action='https://www.ccavenue.com/shopzone/cc_details.jsp'>" +
          "<input type=hidden name='Merchant_Id' value='" + config.merchantId + "'>" +
          "<input type=hidden name='Amount' value='" + config.orderAmount + "'>" +
          "<input type=hidden name='Order_Id' value='" + config.orderId + "'>" +
          "<input type=hidden name='Redirect_Url' value='" + config.redirectUrl +"'>" +
          "<input type=hidden name='Checksum' value='" + Checksum + "'>" +
          "<input type=hidden name='TxnType' value='A'>" +
          "<input type=hidden name='ActionID' value='TXN'>";

          for(var key in otherParams) {
                body += "<input type=hidden name='"+ key +"' value='" + otherParams[key] + "'>";
          }

          body += "</form><script type='text/javascript'>" +
              "document.getElementById('checkout').submit();" +
          "</script>";

    res.writeHead(200, {
        'Content-Length': Buffer.byteLength(body),
        'Content-Type': 'text/html'
    });

    res.write(body);
    res.end();
}

我假设您使用的是较旧版本的hapi 17.0.0，以便使用html进行回复。此外，本示例教程也会有所帮助

. 哈皮会为你做大部分的工作。如果您想使用节点的res和req http服务器对象，您需要从hapi的内部公开原始请求和响应对象，如raw属性下所述。

谢谢，我需要将

res.write

和

res.writeHead

替换为

res（body）
