我正在尝试获取youtube的搜索结果页面。这里我输入了视频名称，我正在尝试获取搜索结果的html页面。
我使用http模块来发送和接收数据。
var youtube_query=querystring.stringify({
'search_query':'bangarang', //video name
'spf':'navigate'
});
var options_you = { //headers for searching in youtube
host:'www.youtube.com',
path:'/results',
method:'GET',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': Buffer.byteLength(youtube_query),
'User-Agent': 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36'
}
};
function getvid_id(vid_result){
//callback function for finding the getting the result page
vid_result.setEncoding('utf8');
vid_result.on('data', function (chunk) {
console.log(chunk);
});
}
var youtube_request = http.request(options_you,getvid_id);
youtube_request.on('error', function(e) {
console.log('problem with request: ' + e.message);
});
youtube_request.write(youtube_query);
youtube_request.end();
这是我收到的结果页面

我无法理解恶意网址的原因
最佳答案
检查您的内容长度行，这会导致网址格式错误
'Content-Length': Buffer.byteLength(youtube_query)
如果您删除 content-length ，它可以工作，但随着 url 的移动，您最终可能会收到 301 错误。因此您可能需要使用 follow-redirects 模块
var http = require("follow-redirects").http;
或者您可以使用“请求”模块
