Question

当我直接在网络浏览器中点击网址时，会下载正确的csv文件。如果我使用nodejs下载文件，则文件会下载，但它包含html代码而不是我需要的数据。

var http = require('http');
var fs = require('fs');

var file = fs.createWriteStream("history/a.csv");
var request = http.get("http://www.google.com/finance/historical?q=AAL&startdate=Feb+28+2017&output=csv", function(response) {
  response.pipe(file);
});

生成的文件：<!DOCTYPE html><html lang=en><meta charset=utf-8><meta name=viewport content="initial-scale=1 minimum-scale=1 width=device-width"><title>Error 404 (Not Found)!!1</title><style>*{margin:0;padding:0}html code{font:15px/22px arial sans-serif}html{background:#fff;color:#222;padding:15px}body{color:#222;text-align:unset;margin:7% auto 0;max-width:390px;min-height:180px;padding:30px 0 15px;}* > body{background:url(//www.google.com/images/errors/robot.png) 100% 5px no-repeat;padding-right:205px}p{margin:11px 0 22px;overflow:hidden}pre{white-space:pre-wrap;}ins{color:#777;text-decoration:none}a img{border:0}@media screen and (max-width:772px){body{background:none;margin-top:0;max-width:none;padding-right:0}}#logo{background:url(//www.google.com/images/branding/googlelogo/1x/googlelogo_color_150x54dp.png) no-repeat;margin-left:-5px}@media only screen and (min-resolution:192dpi){#logo{background:url(//www.google.com/images/branding/googlelogo/2x/googlelogo_color_150x54dp.png) no-repeat 0% 0%/100% 100%;-moz-border-image:url(//www.google.com/images/branding/googlelogo/2x/googlelogo_color_150x54dp.png) 0}}@media only screen and (-webkit-min-device-pixel-ratio:2){#logo{background:url(//www.google.com/images/branding/googlelogo/2x/googlelogo_color_150x54dp.png) no-repeat;-webkit-background-size:100% 100%}}#logo{display:inline-block;height:54px;width:150px}</style><div id="af-error-container"><a href=//www.google.com/><span id=logo aria-label=Google></span></a><p><b>404.</b> <ins>Thatâ€™s an error.</ins><p>The requested URL was not found on this server. <ins>Thatâ€™s all we know.</ins></div>
