URI中特殊字符的处理

#### 一、问题产生场景 ####

实际项目开发中，需要通过get请求传递一个zip包的地址参数，zip地址中含有特殊字符

#### 二、URL特殊符号及编码十六进制值 ####

<table> 
 <thead> 
  <tr> 
   <th>特殊字符</th> 
   <th>十六进制值</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>+</td> 
   <td>%2B</td> 
  </tr> 
  <tr> 
   <td>空格</td> 
   <td>URL中的空格可以用+号或者编码 %20</td> 
  </tr> 
  <tr> 
   <td>/</td> 
   <td>%2F</td> 
  </tr> 
  <tr> 
   <td>?</td> 
   <td>%3F</td> 
  </tr> 
  <tr> 
   <td>%</td> 
   <td>%25</td> 
  </tr> 
  <tr> 
   <td>#</td> 
   <td>%23</td> 
  </tr> 
  <tr> 
   <td>&amp;</td> 
   <td>%26</td> 
  </tr> 
  <tr> 
   <td>=</td> 
   <td>%3D</td> 
  </tr> 
 </tbody> 
</table>

#### Java实现url encoding ####

import org.apache.http.client.HttpClient;
    import org.apache.http.client.methods.HttpGet;
    import java.net.URLEncoder;
    
    try {
           String url = "http://10.238.6.8:8180/PbDeserialize-service/pbdeserialize/pbfileupdate?pbupdatefile=" + URLEncoder.encode(pbupdatefile, "utf-8");
           URI uri = new URI(url);
           System.out.println("uri:" + uri);
           HttpClient httpClient = null;
           HttpGet getMethod = null;
           HttpResponse response = null;
           getMethod = new HttpGet(uri);
           //设置请求头
          getMethod.addHeader("Content-Type", "application/json");
          getMethod.addHeader("Accept-Encoding", "application/json");
          response = httpClient.execute(getMethod);
          int statusCode = response.getStatusLine().getStatusCode();
          System.out.println("HTTP Status Code:" + statusCode);
          if (statusCode != HttpStatus.SC_OK) {
                System.out.println("HTTP 请求未成功！HTTP Status Code：" + response.getStatusLine());
          }
          HttpEntity httpEntity = response.getEntity();
          System.out.println("httpEntity:" + httpEntity);
          String responseContent = null;
          responseContent = EntityUtils.toString(httpEntity, "UTF-8");
          //释放资源
          EntityUtils.consume(httpEntity);
          System.out.println("响应内容: " + responseContent);
          } catch (IOException e) {
              e.printStackTrace();
          } catch (URISyntaxException e) {
              e.printStackTrace();
          }catch (NullPointerException e){
              e.printStackTrace();
          }
