使用了linux服务器，发布.net8的webapi，其中登录接口调用了微信小程序获取手机号的接口，本地测试环境一直没有问题，当发布到服务器之后一直报：The SSL connection could not be established, see inner exception.
一直怀疑证书配置问题，或者是我的nginx配置证书不正确的问题，也怀疑是docker镜像内部无法访问微信小程序接口的问题；
最后发现和服务器没有关系，是我自己的程序里面在调用微信小程序接口的时候，使用了HttpWebRequest,这个比较老了，很多都不支持这种了，所以一直报错，最后换成httpclient调用post接口就可以了；
老旧的调用方法如下：
public static string Post(string url, string data) { HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); request.Method = "POST"; using (StreamWriter streamWriter = new StreamWriter(request.GetRequestStream())) { streamWriter.Write(data); } HttpWebResponse response = (HttpWebResponse)request.GetResponse(); using (StreamReader readStream = new StreamReader(response.GetResponseStream(), Encoding.UTF8)) { return readStream.ReadToEnd(); } }
新的成功的调用方法如下：
private static string PostResponse(string url, string con)
{
//if (url.StartsWith("https"))
// System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls;
if (url.StartsWith("https"))
{
// 启用所有支持的 TLS 版本
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls13 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;
}
string resString = null;
using (HttpClient httpClient = new HttpClient())
{
httpClient.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
var content = new StringContent(con);
HttpResponseMessage response = httpClient.PostAsync(url, content).Result;
if (response.IsSuccessStatusCode)
{
resString = response.Content.ReadAsStringAsync().Result;
}
}
return resString;
}
