res.writehead 和 res.write 的 hapi 等价物是什么？

Question

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，因此会产生错误。那么，res.writehead 和 res.write.

的 hapi 等价物是什么？

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);
        }
    });

}

这是模块函数：

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();
}

这是错误：

我假设您使用的是旧版本的 hapi 17.0.0，为了使用 html 回复 https://github.com/hapijs/vision。此示例教程也应该有所帮助 https://futurestud.io/tutorials/hapi-how-to-render-views. Hapi will do most of the work for you. If you want to use node's res and req http server objects you need to expose the raw request and response objects from hapi's internals as documented here https://hapijs.com/api/16.5.2#request-properties 在原始属性.
