JAVA - SSL - 客户端证书(JAVA - SSL - Client Certifcates)

 我一直在使用JAVA开发一个WS客户端，我遇到了SSL身份验证问题。 WS是在WCF上创建的，我无权访问服务器，它们通过HTTPS工作并使用需要首先在客户端上安装的客户端证书。 服务器人员发给我一个PFX证书，我成功安装在操作系统上（我使用OS X）然后我可以通过浏览器访问WS（Safari或FF都是我尝试过的，以前无法访问WSs ）。 我认为操作系统中的任何应用程序都会使用此证书，但是当我尝试使用我的JAVA应用程序时，它无效; 首先抛出以下错误：  
 “javax.net.ssl.SSLHandshakeException：sun.security.validator.ValidatorException：PKIX路径构建失败：sun.security.provider.certpath.SunCertPathBuilderException：无法找到所请求目标的有效证书路径”  
 我通过将证书导出到CER文件并使用keytool命令行工具将证书添加到JAVA使用的“cacerts”keyStore中来解决了这个问题。 但是在这个错误消失后，下面开始出现：“403，禁止”。 这显然是因为它没有为网站使用SSL客户端证书，但我找不到将其发送给它的方法。 任何帮助，将不胜感激。  
 以下是我用来发布到WS的代码：  
URL url = new URL(p_url);

HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.setDoOutput(true);

conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", contentType);

OutputStream out = conn.getOutputStream(); // on this line it shows the error

I've been developing a WS client using JAVA and I'm having a problem with SSL authentication. The WS are created on WCF and I have no access to the server, they work through HTTPS and uses a client certificate that needs to be installed on the client first. The server guys sent me a PFX certificate which I successfully installed on the OS (I'm using OS X) and I could then access the WS via a browser (Safari or FF are both that I tried which previously couldn't access the WSs). I thought any app in the OS would use this certs but when I'm tried my JAVA app it didn't work; at first the following error was being thrown: 
"javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"  
I solved this by exporting the certificate to a CER file and using the keytool command line tool to add the certificate into the "cacerts" keyStore JAVA uses. But after this error went away the following started appearing: "403, forbidden". This is obviously because it's not using the SSL client cert for the site but I haven't been able to find a way to send it to it. Any help would be appreciated. 
The following is the code I use to post to the WS: 
URL url = new URL(p_url);

HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.setDoOutput(true);

conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", contentType);

OutputStream out = conn.getOutputStream(); // on this line it shows the error

 使用导航属性或保存之前，因此EF Core可以填充主键（仅在保存实体后才会发生）。  
public class ProductExtension
{
    public int ProductId { get; set; }
    public Product Product { get; set; }
    public string Notes { get; set; }
}
 
 现在你可以使用了  
Product product = new Product();
product.Name = "Phone";

ProductExtension = productExtension = new ProductExtension();
// assign the whole model to the navigation property
productExtension.Product = product;
productExtension.Notes = "some notes";

// no need for this anymore
// context.Products.Add(product);
//Add and save
context.ProductExtensions.Add(productExtension);
context.SaveChangesAsync();

Use navigation property or save before, so EF Core can populate the primary keys (happens only after the entity is saved). 
public class ProductExtension
{
    public int ProductId { get; set; }
    public Product Product { get; set; }
    public string Notes { get; set; }
}
 
Now you can use  
Product product = new Product();
product.Name = "Phone";

ProductExtension = productExtension = new ProductExtension();
// assign the whole model to the navigation property
productExtension.Product = product;
productExtension.Notes = "some notes";

// no need for this anymore
// context.Products.Add(product);
//Add and save
context.ProductExtensions.Add(productExtension);
context.SaveChangesAsync();
