我使用本教程配置和设置了莱特币守护进程（它与比特币守护进程相同）：https ://forum.litecoin.net/index.php?topic=43.0
一切都很好，但是，当我尝试通过下面的代码远程向它发送命令时（thesite.com 替换为我的实际 IP，与 user:pass 相同）
$litecoin = new jsonRPCClient('http://user:pass@thesite.com:8332/');
echo $litecoin->getinfo();
在我的 litecoin.conf 文件中，我有：
rpcallowip=1.1.1.1
rpcallowport=8332
server=1
daemon=1
rpcuser=user
rpcpassword=pass
它返回此错误：
警告：fopen（http://...@thesite.com:8332/）：无法打开流：第 132 行 /var/www/html/gawk/jsonRPCClient.php 中的连接被拒绝致命错误：未捕获的异常“异常” ' 带有消息 '无法连接到http://user:pass@thesite.com:8332/ ' 在 /var/www/html/gawk/jsonRPCClient.php:140 堆栈跟踪：#0 /var/www/html/ gawk/index.php(27): jsonRPCClient->__call('getinfo', Array) #1 /var/www/html/gawk/index.php(27): jsonRPCClient->getinfo() #2 {main} 抛出在 /var/www/html/gawk/jsonRPCClient.php 第 140 行
当我在本地（从托管守护程序的服务器）发送命令时它可以工作，但我需要能够远程发送命令。
我正在使用下面的 JSON-RPC 类：
