restful服务接口访问乱码 和 505错误_aws 文件url有空格 505

用cxf 发部个rest服务，用浏览器访问和 HttpURLConnection 访问。

1. URL中有中文，浏览器访问正常，HttpURLConnection 失败。

解决： HttpURLConnection 方式需要做兼容处理。

queryParam 传入参数，服务实现方法中要处理，如果是乱码要转换，如果中文直接查询

if (!isChineseChar(queryParam))
 {
      queryParam = new String(queryParam.getBytes("iso8859-1"), "utf-8");
 }
 
// 判断中文
public static boolean isChineseChar(String str)
    {
        boolean temp = false;
        Pattern p=Pattern.compile("[\u4e00-\u9fa5]");
        Matcher m=p.matcher(str);
        if(m.find()){
            temp =  true;
        }
        return temp;
    }

2. HttpURLConnection 请求中 参数中如果有  空格，请求则会 505错误

解决： 需要对有空格的参数 做URL编码处理。

修改后  正常ok
