Java后端可以使用HttpServletRequest对象获取请求参数,然后将获取到的参数添加到封装的htmlUtils请求中。具体步骤如下:
1. 在Controller中获取HttpServletRequest对象,代码如下:
```java
@RequestMapping("/video")
public String getVideo(HttpServletRequest request) {
String param1 = request.getParameter("param1");
String param2 = request.getParameter("param2");
// 将获取到的参数添加到htmlUtils请求中
HtmlUtils htmlUtils = new HtmlUtils();
htmlUtils.addParam("param1", param1);
htmlUtils.addParam("param2", param2);
// 请求别的视频网站
String result = htmlUtils.sendRequest("http://www.otherwebsite.com/video");
// 处理结果并返回
return result;
}
```
2. 在htmlUtils中添加addParam方法,用于将请求参数添加到请求中,代码如下:
```java
public void addParam(String name, String value) {
if (params == null) {
params = new ArrayList<>();
}
params.add(new BasicNameValuePair(name, value));
}
```
3. 在htmlUtils中添加sendRequest方法,用于发送请求并获取响应结果,代码如下:
```java
public String sendRequest(String url) {
HttpClient httpClient = HttpClientBuilder.create().build();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params, StandardCharsets.UTF_8));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
String result = EntityUtils.toString(httpEntity, StandardCharsets.UTF_8);
return result;
}
```
以上就是Java后端获取request请求参数添加到封装的htmlUtils请求中,再请求别的视频网站的步骤。
