总是返回sn校验失败，原因是 location的参数有逗号，在按照官方实例时，不能处理一种参数形式，那就是参数中不只有中文，还有其他特殊字符，比如逗号；就会导致sn错误

/ 对url内参数的所有value作utf8编码，拼接返回结果 public String toQueryString(Map<?, ?> data) throws UnsupportedEncodingException {StringBuffer queryString = new StringBuffer();for (Entry<?, ?> pair : data.entrySet()) {queryString.append(pair.getKey() + "="); queryString.append(URLEncoder.encode((String) pair.getValue(), "UTF-8") + "&");}if (queryString.length() > 0) {queryString.deleteCharAt(queryString.length() - 1);}return queryString.toString(); }

解决方法 改下toQueryString

//针对location参数的改进public String toQueryString(Map<?, ?> data) throws UnsupportedEncodingException {StringBuffer queryString = new StringBuffer();for (Entry<?, ?> pair : data.entrySet()) {queryString.append(pair.getKey() + "="); String ss[] = pair.getValue().toString().split(","); if(ss.length>1){for(String s:ss){queryString.append(URLEncoder.encode(s,"UTF-8") + ",");}queryString.deleteCharAt(queryString.length()-1); queryString.append("&"); } else{queryString.append(URLEncoder.encode((String) pair.getValue(), "UTF-8") + "&"); }}if (queryString.length() > 0) {queryString.deleteCharAt(queryString.length() - 1);}return queryString.toString(); }
