XML-RPC
XML-RPC的java实现

apache提供的api

自定义实现XMLRpcServer
入口
在SpringBoot的入口函数中加入下面代码
public static final String CONSTANT_XMLRPC_NAME = "/xmlrpc";
@SuppressWarnings({"unchecked", "rawtypes"})
@Bean
public ServletRegistrationBean registerServlet() {
return new ServletRegistrationBean(
new XmlRpcServlet(),
CONSTANT_XMLRPC_NAME // xml-rpc访问接口
);
}
SPI配置文件
代码如下
blogger=com.terwergreen.bugucms.coresevice.xmlrpc.MetaWeblogImpl
metaWeblog=com.terwergreen.bugucms.coresevice.xmlrpc.MetaWeblogImpl

图床支持
实现 newMediaObject 即可，代码如下：
@Override
public Map<String, String> newMediaObject(String blogid, String username, String password, Map<String, Object> post) throws XmlRpcException {
logger.info("metaWeblog.newMediaObject -> blogid: {}", blogid);
isValid(username, password);
Map<String, String> urlData = new HashMap<>();
try {
String retUrl = "http://oss.terwergreen.com/%s";
String name = post.get("name").toString();
// {year}/{mon}/{day}/{filename}{.suffix}
Date now = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd");
String forder = sdf.format(now);
System.out.println("forder = " + forder);
String fileName = "bugucms/" + forder + "/" + name;
String url = String.format(retUrl, fileName);
byte[] bits = (byte[]) post.get("bits");
logger.info("准备上传图片，url = " + url);
// 开始上传图片
OssManager manager = OssManager.getInstance();
manager.upload(fileName, bits);
// 水印
// String watermark = String.format("?x-oss-process=%s", "image/auto-orient,1/quality,q_90/format,jpg/watermark,image_YnVndWNtcy9sb2dvLWRhcmsucG5nP3gtb3NzLXByb2Nlc3M9aW1hZ2UvcmVzaXplLFBfNjI,g_se,x_10,y_10");
// String markedUrl = url + watermark;
urlData.put("url", url);
} catch (Exception e) {
e.printStackTrace();
logger.error("图片上传错误", e);
}
logger.info("urlData = {}", urlData);
return urlData;
}
