微信公众平台-微信服务号开发

代码示例:
//解析
@GetMapping("/weChatParseXml")
public String parseXmlGet(@RequestParam("signature") String signature,
@RequestParam("timestamp") String timestamp,
@RequestParam("nonce") String nonce,
@RequestParam("echostr") String echostr) {
logger.info("signature: " + signature);
logger.info("timestamp: " + timestamp);
logger.info("nonce: " + nonce);
logger.info("echostr: " + echostr);
//排序
String[] strArray = {TOKEN, timestamp, nonce}; //TOKEN为公众平台填写的Token
Arrays.sort(strArray);
StringBuilder sb = new StringBuilder();
for (String str : strArray) {
sb.append(str);
}
String sortString = sb.toString();
logger.info("sortString: " + sortString);
//加密  这里主要是进行sha1加密 可以使用 SecurityUtil工具类进行加密
String myString = weChatAppletBiz.weChatParseXmlSha1(sortString);
logger.info("myString: " + myString);
//校验
if (myString != null && myString != "" && myString.equals(signature)) {
logger.info("签名校验通过");
//如果检验成功原样返回echostr，微信服务器接收到此输出，才会确认检验完成。
return echostr;
} else {
logger.info("签名校验失败");
return "";
}
}
