我试图弄清楚如何使用node.js发出HTTP PUT请求。我尝试了很多不同的方法，但是无法正常工作。

这个想法是要有一种放置文件的方法，例如：

function putFile(file_path,callback) {
    // Put the file
}

任何帮助，将不胜感激。

/// <summary>
        /// 通用请求方法
        /// </summary>
        /// <param name="url"></param>
        /// <param name="datas"></param>
        /// <param name="method">POST GET PUT DELETE</param>

        /// <returns></returns>
        public static string HttpRequest(string url, string data, string method = "PUT", string contentType = "application/json", Encoding encoding = null)
        {

            byte[] datas = System.Text.Encoding.GetEncoding("UTF-8").GetBytes(data);//data可以直接传字节类型 byte[] data,然后这一段就可以去掉
            if (encoding == null)
                encoding = Encoding.UTF8;
            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
            request.Method = method;
            request.Timeout = 150000;
            request.AllowAutoRedirect = false;
            if (!string.IsNullOrEmpty(contentType))
            {
                request.ContentType = contentType;
            }
            if (url.StartsWith("https", StringComparison.OrdinalIgnoreCase))
            {
                ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(CheckValidationResult);
            }
            Stream requestStream = null;
            string responseStr = null;
            try
            {
                if (datas != null)
                {
                    request.ContentLength = datas.Length;
                    requestStream = request.GetRequestStream();
                    requestStream.Write(datas, 0, datas.Length);
                    requestStream.Close();
                }
                else
                {
                    request.ContentLength = 0;
                }
                using (HttpWebResponse webResponse = (HttpWebResponse)request.GetResponse())
                {
                    Stream getStream = webResponse.GetResponseStream();
                    byte[] outBytes = ReadFully(getStream);
                    getStream.Close();
                    responseStr = Encoding.UTF8.GetString(outBytes);
                }
            }
            catch (Exception)
            {
                throw;
            }
            finally
            {
                request = null;
                requestStream = null;
            }
            return responseStr;
        }

private static bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
        {
            return true; //总是接受  
        }

public static byte[] ReadFully(Stream stream)
        {
            byte[] buffer = new byte[512];
            using (MemoryStream ms = new MemoryStream())
            {
                while (true)
                {
                    int read = stream.Read(buffer, 0, buffer.Length);
                    if (read <= 0)
                        return ms.ToArray();
                    ms.Write(buffer, 0, read);
                }
            }
        }

Accept = "Accept" ":" #( media-range [ accept-params ] )

解决方法

URL url = new URL("https://stackoverflow.com");
HttpURLConnection urlConnection = (HttpURLConnection)  url.openConnection();
urlConnection.setRequestProperty("Accept","application/json");
try {
    InputStream in = new BufferedInputStream(urlConnection.getInputStream());
    ...
} finally {
    urlConnection.disconnect();
}

如何在Node.js或Express.js中发出HTTP请求？我需要连接到另一个服务。我希望该调用是异步的，并且该回调包含远程服务器的响应。

var $q = require('q'),_ = require('lodash'),path = require('path'),Qs = require('qs'),uuid = require('node-uuid'),https = require('https');

var params = {
  schema: '1.0',form: 'json',username: 'name'
}
var options = {
  host: 'openshift.redhat.com',port: 443,path: '/broker/rest/api',query: params
};

var req = https.get(options,function(res) {
