PHP SOAP -无法连接到主机错误消息(皇家邮政运输API集成)

我正在设置初始的皇家邮政航运API集成，并有以下PHP代码(注:我仍在等待皇家邮政的一些凭据，但此代码应该至少仍然连接&给我某种形式的认证错误。

我在本地运行了PHPINFO()，可以确认CURL &已启用OpenSSL。不太确定还有什么原因会导致这种情况……什么好主意吗?

我已经关闭了Windows防火墙，URL为http://localhost/royalmail/index.php

当我在浏览器中运行这个时，我得到了错误-这发生在代码块中大约一半的try块中。

Could not connect to host

我还没有创建*。pem文件用于此-我在指南中阅读了这一点。我创建了三个*。Pem文件(cacert. Pem)。pem, mycert。pem,Mykey.pem)，但我不知道现在该怎么处理它们?

pkcs# 12 [http://en.wikipedia.org/wiki/PKCS_12]是从1996年开始的原始行业标准，用于安全传输证书和私钥(类似于加密的zip存档)，并由各种应用程序和操作系统直接支持。这提供了一种标准化的"单一文件"方式来安全地传递证书、它的私钥和CA的公共签名证书的副本。

Linux和BSD上的标准web服务器是Apache，它期望所有的证书和密钥都是Base64编码版本的CER/DER x509v3二进制证书格式和RSA/DSA密钥。

在Linux上使用以下OpenSSL工具集命令从pkcs# 12文件(mycert.p12)中提取组成部分很容易。

% openssl pkcs12 -in mycert。P12 -cacerts -nokeys -out cacerts .pem

% openssl pkcs12 -in mycert。P12 -clcerts -nokeys out mycert.pem

% openssl pkcs12 -in mycert。P12 -nocerts -nodes -out mykeypem

"cacert。pem"文件包含CA的公开签名。通常，它被添加到系统范围的"可信CA"文件中(例如/etc/ssl/certs/ca-certificates)。CRT等)或可以直接引用的应用程序使用的文件本身。需要此证书来正式验证由同一CA颁发的任何证书。

通常是"mycert. net"。pem文件中包含pem编码的x509v3格式的"客户端SSL"证书。这用于在建立SSL/TLS连接时对服务器进行客户端身份验证。

"mykey。pem"文件包含链接到客户端证书的(现在)未加密的pem编码的RSA 2048位私钥。

应用程序在建立与应用程序和环境相关的SSL网络连接时如何传递已颁发的客户端SSL证书，但它本质上需要访问"mycert. net"answers"mycert. net"。Pem"answers"mykey"。Pem"文件，或者在某些情况下，包含证书和密钥的单个组合文件。
