我想使用 Node js 中的请求模块向页面发出请求，但这有一个错误 500 。 这是 json 响应的一部分
{
"readable": false,
"domain": null,
"_maxListeners": 10,
"httpVersion": "1.1",
"complete": true,
"_pendingIndex": 0,
"url": "",
"method": null,
"statusCode": 500,
"_consuming": true,
"_dumped": false,
"httpVersionMajor": 1,
"httpVersionMinor": 1,
"upgrade": false,
"body": "<!DOCTYPE HTML PUBLIC \"-//IETF//DTD HTML 2.0//EN\">\n<html><head>\n<title>500 Not Found</title>\n</head><body>\n<h1>Not Found</h1>\n<p>The requested\n site <a href=\"http:// HTTP/1.1/\"> HTTP/1.1</a> is not presently available on\n this <a href=\"http://www.hybrid-cluster.com/\">web cluster</a>.\n This may be a temporary issue, so please try again in a few\n moments.</p>\n\n</body></html>\n",
"_readableState": {
"highWaterMark": 16384,
"length": 0,
"pipes": null,
"pipesCount": 0,
"flowing": false,
"ended": true,
"endEmitted": true,
"reading": false,
"calledRead": true,
"sync": false,
"needReadable": true,
"emittedReadable": false,
"readableListening": false,
"objectMode": false,
"defaultEncoding": "utf8",
"ranOut": false,
"awaitDrain": 0,
"readingMore": false,
"decoder": null,
"encoding": null,
"buffer": []
},
这是我用于请求的代码
app.get('/', function(req, res){
var options = {
url: 'http://www.metallicabyrequest.com/'
}
request(options, function (error, response, html) {
/*if (!error && response.statusCode == 200) {
res.json(html);
}*/
if(error){
res.json(error);
}else{
res.json(response)
}
});
});
有什么方法可以防止错误 500？我读到，如果您更改 header ，请求可能有效，但我不知道该怎么做...
最佳答案
该站点在请求 header 中需要“主机”:
var options = {
url: 'http://www.metallicabyrequest.com/',
headers: {
'Host': 'www.metallicabyrequest.com'
}
}
