HttpHelper之我见
前几月一直用一个Http的访问类去调用WebApi,说句实话最开始没觉有什么,一是技术老,二是觉得比较简单,但是最近我一直关注云开发和AI这块儿微软技术,看到云平台调用API大多类似,所以回想这个早年的调用方式,感觉有老汤炖肉之感,实用又有价值,可以作为认识调用API的学习和使用,回味无穷。
using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Net; using System.Net.Security; using System.Security.Cryptography.X509Certificates; using System.Text; using System.Web; namespace Bussiness.Helper { public class HttpHelper { /// <summary> /// 创建GET方式的HTTP请求 /// </summary> public static HttpWebResponse CreateGetHttpResponse(string url, int timeout, string userAgent, CookieCollection cookies) { HttpWebRequest request = null; if (url.StartsWith("https", StringComparison.OrdinalIgnoreCase)) { //对服务端证书进行有效性校验(非第三方权威机构颁发的证书,如自己生成的,不进行验证,这里返回true) ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(CheckValidationResult); request = WebRequest.Create(url) as HttpWebRequest; request.ProtocolVersion = HttpVersion.Version10; //http版本,默认是1.1,这里设置为1.0 } else { request = WebRequest.Create(url) as HttpWebRequest; } request.Method = "GET"; request.Headers.Add("Origin", "http://" + request.Host); //设置代理UserAgent和超时 //request.UserAgent = userAgent; //request.Timeout = timeout; if (cookies != null) { request.CookieContainer = new CookieContainer(); request.CookieContainer.Add(cookies); } return request.GetResponse() as HttpWebResponse; } /// <summary> /// 创建POST方式的HTTP请求 /// </summary> public static HttpWebResponse CreatePostHttpResponse(string url, IDictionary<string, string> parameters, int timeout, string userAgent, CookieCollection cookies) { HttpWebRequest request = null; //如果是发送HTTPS请求 if (url.StartsWith("https", StringComparison.OrdinalIgnoreCase)) { //ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(CheckValidationResult); request = WebRequest.Create(url) as HttpWebRequest; //request.ProtocolVersion = HttpVersion.Version10; } else { request = WebRequest.Create(url) as HttpWebRequest; } request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; //设置代理UserAgent和超时 //request.UserAgent = userAgent; //request.Timeout = timeout; if (cookies != null) { request.CookieContainer = new CookieContainer(); request.CookieContainer.Add(cookies); } //发送POST数据 if (!(parameters == null || parameters.Count == 0)) { StringBuilder buffer = new StringBuilder(); int i = 0; foreach (string key in parameters.Keys) { if (i > 0) { buffer.AppendFormat("&{0}={1}", key, parameters[key]); } else { buffer.AppendFormat("{0}={1}", key, parameters[key]); i++; } } //byte[] data = http://www.mamicode.com/Encoding.ASCII.GetBytes(buffer.ToString()); byte[] data =http://www.mamicode.com/ Encoding.UTF8.GetBytes(buffer.ToString()); using (Stream stream = request.GetRequestStream()) { stream.Write(data, 0, data.Length); } } string[] values = request.Headers.GetValues("Content-Type"); return request.GetResponse() as HttpWebResponse; } /// <summary> /// 获取请求的数据 /// </summary> public static string GetResponseString(HttpWebResponse webresponse) { var result = string.Empty; using (Stream s = webresponse.GetResponseStream()) { StreamReader reader = new StreamReader(s, Encoding.UTF8); result = reader.ReadToEnd(); } return result; } /// <summary> /// 验证证书 /// </summary> private static bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors) { if (errors == SslPolicyErrors.None) return true; return false; } } }
特备提示:
乱码现象,注意改这里:
//byte[] data = http://www.mamicode.com/Encoding.ASCII.GetBytes(buffer.ToString());
byte[] data = http://www.mamicode.com/Encoding.UTF8.GetBytes(buffer.ToString());
调用方式:
Dictionary<String, String> pList = new Dictionary<String, String>(); pList.Add("Location", userLog.Location); pList.Add("Name", userLog.Name); ResultModel resultModel = new ResultModel(); var apiDomain = ConfigurationManager.AppSettings["ApiDomain"]; var url = @"" + apiDomain + "/api/AD/DeleteOneUser"; // var url = @"" + apiDomain + "/api/AD/GetEmail"; try { var response = HttpHelper.CreatePostHttpResponse(url, pList, 0, string.Empty, null); var info = HttpHelper.GetResponseString(response).Replace("\\", ""); //info = info.Substring(1, info.Length - 2); //string intoStr = "{" + info + "}"; resultModel = Newtonsoft.Json.JsonConvert.DeserializeObject<ResultModel>(info); } catch(){}
