org.apache.commons.httpclient.HttpClient设置http请求的超时时间
时间: 2023-10-01 07:05:39 浏览: 191
如果你使用的是Apache Commons HttpClient,可以通过以下方式来设置HTTP请求的超时时间:
1. 设置连接超时时间
```
HttpClient httpClient = new HttpClient();
httpClient.getHttpConnectionManager().getParams().setConnectionTimeout(5000);
```
上面的代码将连接超时时间设置为5秒。
2. 设置请求超时时间
```
HttpClient httpClient = new HttpClient();
httpClient.getHttpConnectionManager().getParams().setSoTimeout(5000);
```
上面的代码将请求超时时间设置为5秒。
需要注意的是,以上两种超时时间设置方式均采用毫秒为单位。另外,Apache Commons HttpClient已经不再维护,推荐使用Apache HttpComponents来发送HTTP请求。

org.apache.commons.httpclient的jar包的使用
org.apache.commons.httpclient是一个Java编程语言中使用的HTTP客户端库。它提供了一个简单的API,允许您使用HTTP协议与Web服务器进行通信。要使用org.apache.commons.httpclient的jar包,您需要执行以下步骤:
1. 下载org.apache.commons.httpclient的jar包,可以从官方网站或者Maven仓库中获取。
2. 将jar包添加到您的Java项目中,可以通过将其复制到项目的lib目录中或者使用Maven等构建工具来完成。
3. 在您的Java代码中导入org.apache.commons.httpclient相关的类和方法。
4. 使用HttpClient类来创建HTTP请求并发送请求到Web服务器。您可以使用GetMethod、PostMethod等方法来发送GET、POST请求等,也可以设置请求头、Cookies、代理等信息。
5. 处理Web服务器的响应,您可以使用ResponseHandler接口来处理响应数据。如果您只需要读取响应的内容,可以使用ResponseBodyHandler类。
示例代码:
```java
import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.methods.*;
import org.apache.commons.httpclient.params.HttpMethodParams;
public class HttpClientExample {
public static void main(String[] args) throws Exception {
// 创建HttpClient实例
HttpClient client = new HttpClient();
// 创建GET方法的实例
GetMethod method = new GetMethod("http://www.baidu.com");
// 设置请求头信息
method.setRequestHeader("User-Agent", "Mozilla/5.0");
// 设置请求超时时间
method.getParams().setParameter(HttpMethodParams.SO_TIMEOUT, 5000);
// 执行HTTP GET请求
int statusCode = client.executeMethod(method);
// 打印服务器返回的状态码
System.out.println("Response status code: " + statusCode);
// 打印服务器返回的响应内容
String responseBody = method.getResponseBodyAsString();
System.out.println("Response body: " + responseBody);
// 释放连接资源
method.releaseConnection();
}
}
```

看起来你在使用 Maven 构建项目时遇到了一些问题。错误日志显示 Maven 找不到 `commons-httpclient:commons-httpclient:jar:3.1` 这个依赖,可能是由于连接到 Maven 仓库时出现了连接超时的问题导致的。你可以尝试再次运行 Maven 并加上 `-e` 参数来查看完整的错误堆栈信息,或者使用 `-X` 参数来启用完整的调试日志。同时,你也可以参考 Maven 的文档或者寻求社区支持来解决这个问题。
