Imgur API调用：443 ENOTFOUND错误疑难解答

Question

每次调用以下node.js代码时，我都会收到相同的错误。 我之前在node.js中没有使用过Authorization Headers，所以我一定做错了。 是帮助还是指向好的文档？ 该代码试图在imgur的库中检索“黄色”。 每次尝试运行控制台时，控制台始终会打印相同的ENOTFOUND错误。

var express = require("express");
var moment = require("moment");
var http = require("http");
var express = require("express");
var moment = require("moment");
var https = require("https");
var mongo = require('mongodb').MongoClient;

var mystatus="";
var app=express();

var imgurClientID = "<my id>";
var imgurClientSecret = "<my client secret>";

var options = {
    hostname: 'https://api.imgur.com/3/gallery/search?q=yellow',
    method: "POST",
    headers:{
       Authorization: imgurClientID, 
    }
}

app.get('/home', function(req,res){
var myreq = https.request(options, function(res){
    console.log('Status: '+res.statusCode);
    console.log('Headers: '+JSON.stringify(res.headers));
    res.setEncoding('utf8');
    res.on('data', function(body){
        console.log("Body: "+body);
    });
});
myreq.on('error', function(e){
    console.log("Error!: "+e);
})

myreq.end();

});

Answer 1

尝试：

var options = {
    hostname: 'api.imgur.com',
    path: '/3/gallery/search?q=yellow',
    method: "POST",
    headers:{
       Authorization: imgurClientID, 
    }
}

您会收到该错误，因为它试图点击https://api.imgur.com/3/gallery/search?q=yellow:443 ，以上内容应将其发送到正确的位置
