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:

有谁知道可能出了什么问题?

更改此代码:

rpcallowip=1.1.1.1

但请注意,暴露您的端口会带来安全问题。从配置文档:

# By default, only RPC connections from localhost are allowed.  Specify
# as many rpcallowip= settings as you like to allow connections from
# other hosts (and you may use * as a wildcard character).
# NOTE: opening up the RPC port to hosts outside your local
# trusted network is NOT RECOMMENDED, because the rpcpassword
# is transmitted over the network unencrypted.
