Windows IIS ASP.NET Core中创建和使用HTTPS自签名证书教程

为什么要用Https就不说了。

第一步：创建自签名的证书。在Windows下开启PowerShell，将以下文字粘贴进去：

<pre class="brush:csharp;gutter:true;"># setup certificate properties including the commonName (DNSName) property for Chrome 58+
$certificate = New-SelfSignedCertificate `
    -Subject 改成自己想要的标题不要带乱七八糟的符号（安装证书的时候会显示这个） `
    -DnsName 友好域名 `
    -KeyAlgorithm RSA `
    -KeyLength 2048 `
    -NotBefore (Get-Date) `
    -NotAfter (Get-Date).AddYears(2) `
    -CertStoreLocation "cert:CurrentUser\My" `
    -FriendlyName "证书的友好名称，在IIS指定的时候显示Certificate for .NET Core" `
    -HashAlgorithm SHA256 `
    -KeyUsage DigitalSignature, KeyEncipherment, DataEncipherment `
    -TextExtension @("2.5.29.37={text}1.3.6.1.5.5.7.3.1") 
$certificatePath = 'Cert:\CurrentUser\My\' + ($certificate.ThumbPrint)  

# create temporary certificate path
$tmpPath = "C:\tmp"
If(!(test-path $tmpPath))
{
New-Item -ItemType Directory -Force -Path $tmpPath
}

# set certificate password here
$pfxPassword = ConvertTo-SecureString -String "证书的密码" -Force -AsPlainText
$pfxFilePath = "c:\tmp\证书的名称.pfx"
$cerFilePath = "c:\tmp\证书的名称.cer"

# create pfx certificate
Export-PfxCertificate -Cert $certificatePath -FilePath $pfxFilePath -Password $pfxPassword
Export-Certificate -Cert $certificatePath -FilePath $cerFilePath

# import the pfx certificate
Import-PfxCertificate -FilePath $pfxFilePath Cert:\LocalMachine\My -Password $pfxPassword -Exportable

# trust the certificate by importing the pfx certificate into your trusted root
Import-Certificate -FilePath $cerFilePath -CertStoreLocation Cert:\CurrentUser\Root

# optionally delete the physical certificates (don’t delete the pfx file as you need to copy this to your app directory)
# Remove-Item $pfxFilePath
Remove-Item $cerFilePath

把汉字部分修改成你想要的，然后运行一下，就可以在C：\tmp下面找到你的证书了,一般把它放在网站根目录下即可。

二、站点配置（ASP.NET Core 2.1）

* public void ConfigureServices(IServiceCollection services) 部分：

services.AddMvc(options =>
{
options.Filters.Add(new RequireHttpsAttribute());//所有请求都使用HTTPS
})

* public void Configure(IApplicationBuilder app, IHostingEnvironment env) 部分：

var options = new RewriteOptions().AddRedirectToHttps();
app.UseRewriter(options);
app.UseHttpsRedirection();

三、IIS配置：

经过这几步，你的网站就变成Https的了。
