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：
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
string DaliBaiHospitalJson = HttpPost(dlbzUrl, \”{\\\”FIDATES\\\”:\\\”\” + model.FCYRQSTART + \” 00:00:00\” + \”\\\”,\\\”FIDATEE\\\”:\\
