java.net.URISyntaxException: Illegal character in scheme name at index 0:

开发中遇到了一个异常，在调用云信RESTful API接口时，报了 java.net.URISyntaxException: Illegal character in scheme name at index 0: 这个错：

原始代码：

HttpGet httpGet = new HttpGet(" https://roomserver-dev.netease.im/v1/api/rooms/1");

 解决方法：

使用URI u = new URI (原url)转化

HttpGet httpGet = null;
try{
    URI uri = new URI(urlStr);
    httpGet = new HttpGet(uri);
}catch(Exception e){
    e.printStackTrace();
}

 以下是网上其他的做法，测试也是可行的

HttpGet httpGet = null;
try{
    URL url = new URL(urlStr);
    URI uri = new URI(url.getProtocol(), url.getHost(), url.getPath(), url.getQuery(), null);
    httpGet = new HttpGet(uri);
}catch(Exception e){
    e.printStackTrace();
}
