1、首先加入命名空间:
using System.Net.Security;
using System.Security.Authentication;
using System.Security.Cryptography.X509Certificates;
SSL网站,连接时需要提供证书,对于非必须提供客户端证书的情况,只要返回一个安全确认即可。我的是.NET FrameWork4.0
2、加入以下代码:
public bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
{
//直接确认,否则打不开
return true;
}
3、接收证书进行身份验证ssl,在调用api接口前调用此方法: ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(CheckValidationResult);
以下是完整案例:文章来源:https://www.toymoban.com/news/detail-535575.html
public string HttpPost(string url, string body)
{
Encoding encoding = Encoding.UTF8;
string jsonText = string.Empty;
string dataText1 = string.Empty;
if (string.IsNullOrEmpty(url.Trim()))
{
return "";
}
//接收证书进行身份验证
ServicePointManager.ServerCertificateValidationCallback =
new System.Net.Security.RemoteCertificateValidationCallback(CheckValidationResult);
//ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "POST";
request.Accept = "text/plain, */*; q=0.01";
request.ContentType = "application/json;charset=utf-8";
byte[] buffer = encoding.GetBytes(body);
request.ContentLength = buffer.Length;
request.GetRequestStream().Write(buffer, 0, buffer.Length);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
using (StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8))
{
jsonText = reader.ReadToEnd();
dataText1 = Regex.Replace(jsonText, @"\\", "");
}
return dataText1;
}
调用:
dlbzUrl是调用地址 https://…/api/tddbzzljcxt/zybrxx/vnoentry-query
model.FCYRQSTART 开始时间
model.FCYRQEND 结束时间文章来源地址https://www.toymoban.com/news/detail-535575.html
string DaliBaiHospitalJson = HttpPost(dlbzUrl, "{\"FIDATES\":\"" + model.FCYRQSTART + " 00:00:00" + "\",\"FIDATEE\":\"" + model.FCYRQEND + " 23:59:59" + "\"}");
