最近有个zblog自动发布文章需求，大致看了一下，发现并没有wordpress方便，特别是我还有对接python的要求，大概有几种办法

1. 直接读取/zb_users/c_option.php，暴力写入数据
2. 直接开发一个插件使用zblog内部代码接口
3. 使用zblog本身的xmlrpc

第一种方案为了安全还得自己写鉴权，第二种方案通用性强但是需要对zblog比较了解，第三种方案最方便了，python可以直接使用xmlrpc库对接，由于我已经有wordpress自动发布的python脚本，我想复用这个，因此对zblog的xmlrpc进行改造。

兼容wordpress xmlrpc

找到zb_system/xml-rpc/index.php文件，先在入口判断出增加’mt.supportedMethods’支持，再增加’wp.newPost’支持

case 'mt.supportedMethods':
     $strXML = '<methodResponse><params><param><value><array><data>$%#1#%$</data></array></value></param></params></methodResponse>';
     $strAll = '<value><string>wp.newPost</string></value>';
     echo str_replace("$%#1#%$", $strAll, $strXML);
     break;
case 'wp.newPost':
     $username = (string)$xml->params->param[1]->value->string;
     $password = (string)$xml->params->param[2]->value->string;
     xmlrpc_Verify($username, $password);
     if ($zbp->CheckRights('ArticlePst')) {
         xmlrpc_newPost_as_wp($xml->params->param[3]->value->struct->asXML());
     } else {
         xmlrpc_ShowError(6, __FILE__, __LINE__);
    }
    break;

转化wordpress xmlrpc支持函数如下

function xmlrpc_newPost_as_wp($xmlstring)
{
    global $zbp;
    $xml = simplexml_load_string($xmlstring);
    if ($xml) {
        $post = array();
        foreach ($xml->children() as $x) {
            $a = (string)$x->name;
            if ($a == 'terms_names') {
                $struct = $x->value->struct;
                foreach ($struct->children() as $y) {
                    $a = (string)$y->name;
                    $b = $y->value->children()->asXML();
                    $b = str_replace(array('<array>', '</array>', '<data>', '</data>', '<string>', '</string>', '<value>', '</value>', PHP_EOL), array(''), $b);
                    $post[$a] = $b;
                }
            } else {
                $b = $x->value->children();
                $b = str_replace(array('<array>', '</array>', '<data>', '</data>', '<string>', '</string>'), array(''), $b);
                $post[$a] = $b;
            }
        }
        $_POST['ID'] = 0;
        $_POST['Title'] = $post['post_title'];
        if (strcmp('publish', $post['post_status']) != 0) {
            $_POST['Status'] = 0;

                } else {
                    $_POST['Content'] = $post['post_content'];
                }
            } else {
                $_POST['Content'] = $post['post_content'];
            }
