打开输入流时发生 SSL 错误
我想我想了解 SSL 是如何工作的，我有基于 grails 的应用程序作为应用程序过程的一部分，我们必须打开与第 3 方应用程序的“https”连接。 但遇到以下异常
"sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"
虽然与 URL 的连接工作正常，但当我尝试打开输入流以读取数据时会发生错误。问题是，如果存在证书问题，我在打开连接时应该不会遇到问题吗？ 附上代码片段
try{
URL url= new URL("https://.../..")
def c = url.openConnection()
println("connection successful with Merchant")
def result = c.inputStream.text?.trim() // results in error
println(result)
}
catch (Exception exp){
println("error !!!")
println(exp.getMessage())
}
I guess I am trying to understand how SSL works, I have grails based application as part of application process we have to open "https" connection to a 3rd party application.
But running into following exception
"sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"
Though connection to the URL works fine but error happens when I try to open input Stream for reading data. Question is if there is certificate problem shouldn't I have problem while opening connection ?
code snippet is attached
try{
URL url= new URL("https://.../..")
def c = url.openConnection()
println("connection successful with Merchant")
def result = c.inputStream.text?.trim() // results in error
println(result)
}
catch (Exception exp){
println("error !!!")
println(exp.getMessage())
}

对于刚开始使用 SSL 和证书管理的人来说，这是一个非常常见的问题。我在我的博客上题为“导入非众所周知的证书”的文章中用非常详细的示例和命令回答了这个问题 AllInGeek.com。
This is a very common problem for people starting out with SSL and certificate management. I answer this question with very detailed examples and commands in an article titled, "Importing non-well known certificates" on my blog AllInGeek.com.
这仅意味着您要连接的 Web 服务器或 URL 没有来自授权 CA 的有效证书。
您可以通过另一个 ssl 站点验证这一点
或按照此处的步骤操作：

通过导入服务器证书来解决该问题。
This simply means that the web server or the URL you are connecting to does not have a valid certificate from an authorized CA.
You could verify this with another ssl site
or follow the steps here:

to work around the issue by importing the servers certificate.
