增加自动转义-请求参数放在路径中的配置

[venusdrogon]

see 支持将请求参数放在路径中的配置 #233

如果路径中包含非ASCII字符，不会转义，从而造成请求出错。

例如： https://test.example.com/a 中文 c

建议增加自动转义功能。

例如：

    String scheme = "https";

    String host = "test.example.com";

    String path = "/" + uriPath;

    URI uri = new URI(scheme, host, path, null);

    String regex = scheme + "://" + host + "/";

   uri.toASCIIString().replaceFirst(regex, "");

报错信息如下：

  @Test
    public void testTemplate12(){
        Member member = new Member();
        member.setCode("fei long");
        String resolve = resolve("http://www.baidu.com/${member.code}", member);

        HttpClientUtil.get(resolve);

    }

先只支持 空格转义

其他的以后再说

    private static String rework(String result){
        if (result.contains(SPACE)){
            //W3C标准规定， 当Content-Type为application/x-www-form-urlencoded时，URL中查询参数名和参数值中空格要用加号+替代，
            //所以几乎所有使用该规范的浏览器在表单提交后，URL查询参数中空格都会被编成加号+。

            //而在另一份规范(RFC 2396，定义URI)里, URI里的保留字符都需转义成%HH格式(Section 3.4 Query Component)，因此空格会被编码成%20，加号+本身也作为保留字而被编成%2B，
            //对于某些遵循RFC 2396标准的应用来说，它可能不接受查询字符串中出现加号+，认为它是非法字符。

            //所以一个安全的举措是URL中统一使用%20来编码空格字符。
            result = result.replaceAll(SPACE, "%20");
        }
        return result;
    }
