错误：在Node.js，Express之后写入
我得到以下错误
标题
Caught exception: Error: write after end at ServerResponse.OutgoingMessage.write (_http_outgoing.js:413:15) at ServerResponse.res.write (/home/projectfolder/node_modules/express/node_modules/connect/lib/middleware/compress.js:110:17) at ServerResponse.res.end (/home/projectfolder/node_modules/express/node_modules/connect/lib/middleware/compress.js:116:14) at ServerResponse.res.send (/home/projectfolder/node_modules/express/lib/response.js:154:8) at fn (/home/projectfolder/node_modules/express/lib/response.js:794:10) at View.exports.renderFile [as engine] (/home/projectfolder/node_modules/jade/lib/jade.js:222:12) at View.render (/home/projectfolder/node_modules/express/lib/view.js:76:8) at Function.app.render (/home/projectfolder/node_modules/express/lib/application.js:504:10) at ServerResponse.res.render (/home/projectfolder/node_modules/express/lib/response.js:798:7) at /home/projectfolder/app/controllers/index.js:578:9 是任何人都知道这个错误的原因。 我知道，我们不能写入响应发送后的stream，但我无法find从这里写操作执行，我得到这个错误。 我的app / controllers / index.js文件代码如下。 请帮忙。

我无法find这个错误的原因，请帮助我。提前感谢。
你在这个对象声明中有一个错字：
res.render('index', { container1:data[0]; container2:data[1]; container3:data[2]; container4:data[3]; });
应该：
res.render('index', { container1:data[0], container2:data[1], container3:data[2], container4:data[3] });
