API 网关的path参数如何编码？

当API的path中有参数，而且参数含特殊字符。需要先将参数urlencode后加入path中。不然签名会有问题。此时后端收到的也是urlEncode后的值，如果要获取原值，需要自己在后端进行urlDecode.

    @Test
    public void testPath() throws Exception{
        //请求path
        String host="你的域名";
        //请求path,先将参数处理后再放入path中。        
        String type="中文 123";
        String pathParam= URLEncoder.encode(type,"UTF-8");
        String path = "/"+pathParam;
        Map<String, String> headers = new HashMap<String, String>();
        //（必填）根据期望的Response内容类型设置
        headers.put(HttpHeader.HTTP_HEADER_ACCEPT, "application/json");
        CUSTOM_HEADERS_TO_SIGN_PREFIX.clear();
        Request request = new Request(Method.GET, host, path, AppKey, AppSecret, Constants.DEFAULT_TIMEOUT);
        request.setHeaders(headers);
        request.setSignHeaderPrefixList(CUSTOM_HEADERS_TO_SIGN_PREFIX);
        //调用服务端
        Response response = Client.execute(request);
        System.out.println(JSON.toJSONString(response));
    }
