NodeJS下载CSV文件到缓冲区

Question

我正在尝试下载一个小的csv文件，并需要在处理之前将其存储到变量中：

var http = require('http');

var csvData;
var request = http.get('http://url', function(response) {
  response.pipe(csvData);
});
request.end();

response.pipe() 只适用于文件流，我该如何将响应存储到 csvData 变量中？

只需为data和end事件创建监听器即可：

var http = require('http');

var csvData = '';
var request = http.get('http://url', function(response) {
    response.on('data', function(chunk) {
        csvData += chunk;
    });
    response.on('end', function() {
        // prints the full CSV file
        console.log(csvData);
    });
});
