SAE Java环境访问https报错:java.security.InvalidAlgorithmPara2014-08-26使用SAE的Java一直很顺利,在本地Tomcat测试没有问题,上传到SAE后就报这个错,搜索了一下,大体上是指环境方面的问题,这里分享一下。访问地址:https://api.weibo.com/2/users/show.json错误信息:java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty on Linux, or why is the default truststore empty使用代码:
protected String getJsonString(String urlPath) throws Exception {URL url = new URL(urlPath);HttpURLConnection connection = (HttpURLConnection) url.openConnection();connection.setRequestMethod("GET");connection.connect();InputStream inputStream = connection.getInputStream();// 对应的字符编码转换Reader reader = new InputStreamReader(inputStream, "UTF-8");BufferedReader bufferedReader = new BufferedReader(reader);String str = null;StringBuffer sb = new StringBuffer();while ((str = bufferedReader.readLine()) != null) {sb.append(str);}reader.close();connection.disconnect();return sb.toString();}解决办法:new SaeFetchurl().fetch(url)代码说明:使用SAE自带的SaeFetchurl服务取代自己的代码即可。
