httpget没有setentity()方法

对不起,我的信息有误。实际上,在Apache HttpClient 4.x中,HttpGet对象确实没有直接的`setEntity()`方法,因为它主要用于GET请求,不携带HTTP body。如果你尝试给HttpGet设置实体(Entity),会得到一个IllegalArgumentException。
对于GET请求,你不需要设置实体,可以直接构造HttpGet对象,将URL作为参数传递即可。例如:
```java
HttpGet get = new HttpGet("http://example.com/api?param1=value1¶m2=value2");
CloseableHttpResponse response = httpClient.execute(get);
```
对于POST请求,你应该使用HttpPost类,并调用`setEntity()`方法来添加body内容:
```java
HttpPost post = new HttpPost("http://example.com/api");
post.setHeader("Content-Type", "application/x-www-form-urlencoded"); // 或者"application/json"取决于你的数据格式
List<NameValuePair> nameValuePairs = new ArrayList<>();
nameValuePairs.add(new BasicNameValuePair("param1", "value1"));
nameValuePairs.add(new BasicNameValuePair("param2", "value2"));
StringEntity se = new StringEntity(urlEncode(nameValuePairs));
se.setContentType("application/x-www-form-urlencoded");
post.setEntity(se);
CloseableHttpResponse response = httpClient.execute(post);
```
