methods,data,args,cookies,用于获取url中请求参数的

- `methods`:指定 HTTP 请求的方法,常见的有 GET、POST、PUT、DELETE 等。
- `data`:用于传输数据,通常用于 POST 请求,包含在请求体中。
- `args`:用于传输数据,通常用于 GET 请求,包含在 URL 的查询字符串中。
- `cookies`:用于传输数据,包含在请求头中,用于存储客户端的一些状态信息,例如用户登录信息等。
在 Python 的 requests 库中,可以通过以下方式来使用这些参数:
```
import requests
# GET 请求
response = requests.get(url, params=args, cookies=cookies)
# POST 请求
response = requests.post(url, data=data, cookies=cookies)
```
其中,`url` 为请求的 URL 地址。`params` 和 `data` 参数可以传入一个字典类型的数据,而 `cookies` 参数则需要传入一个 CookieJar 对象。

HttpClient发送Post请求并携带cookie
以下是一个使用HttpClient发送Post请求并携带cookie的示例代码:
```java
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.CookieStore;
import org.apache.http.client.HttpClient;
import org.apache.http.client.config.RequestConfig;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.cookie.Cookie;
import org.apache.http.impl.client.BasicCookieStore;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.util.EntityUtils;
import java.util.ArrayList;
import java.util.List;
public class HttpClientUtil {
public static void main(String[] args) throws Exception {
// 创建HttpClient实例
HttpClient httpClient = HttpClientBuilder.create().build();
// 创建CookieStore实例
CookieStore cookieStore = new BasicCookieStore();
// 创建HttpPost实例
HttpPost httpPost = new HttpPost("http://example.com/login");
// 设置请求参数
RequestConfig requestConfig = RequestConfig.custom()
.setConnectTimeout(5000).setConnectionRequestTimeout(5000)
.setSocketTimeout(5000).build();
httpPost.setConfig(requestConfig);
// 设置请求头
httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");
// 设置请求体参数
List<BasicNameValuePair> parameters = new ArrayList<>();
parameters.add(new BasicNameValuePair("username", "example"));
parameters.add(new BasicNameValuePair("password", "password"));
UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(parameters);
httpPost.setEntity(formEntity);
// 执行HttpPost请求
HttpResponse httpResponse = httpClient.execute(httpPost);
// 获取响应实体
HttpEntity httpEntity = httpResponse.getEntity();
if (httpEntity != null) {
String response = EntityUtils.toString(httpEntity);
System.out.println(response);
}
// 获取Cookie
List<Cookie> cookies = cookieStore.getCookies();
// 创建HttpPost实例
httpPost = new HttpPost("http://example.com/data");
// 设置请求参数
requestConfig = RequestConfig.custom()
.setConnectTimeout(5000).setConnectionRequestTimeout(5000)
.setSocketTimeout(5000).build();
httpPost.setConfig(requestConfig);
// 设置请求头
httpPost.setHeader("Content-Type", "application/json");
httpPost.setHeader("Accept", "application/json");
// 设置请求体参数
String requestBody = "{\"key\":\"value\"}";
httpPost.setEntity(new StringEntity(requestBody, ContentType.APPLICATION_JSON));
// 设置Cookie
httpClient = HttpClientBuilder.create().setDefaultCookieStore(cookieStore).build();
// 执行HttpPost请求
httpResponse = httpClient.execute(httpPost);
// 获取响应实体
httpEntity = httpResponse.getEntity();
if (httpEntity != null) {
String response = EntityUtils.toString(httpEntity);
System.out.println(response);
}
}
}
```
