android httpclient post

在 Android 中使用 HttpClient 进行 POST 请求的示例代码如下：

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;

import java.io.IOException;

public class HttpClientExample {

    public static void main(String[] args) {
        HttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost("http://example.com/api"); // 替换为你的目标 URL

        try {
            // 设置请求体内容
            StringEntity requestEntity = new StringEntity("Hello, Server!");
            httpPost.setEntity(requestEntity);

            // 设置请求头信息
            httpPost.setHeader("Content-Type", "application/json");

            // 发送请求并获取响应
            HttpResponse response = httpClient.execute(httpPost);

            // 解析响应
            HttpEntity responseEntity = response.getEntity();
            String responseBody = EntityUtils.toString(responseEntity);
            System.out.println("Response: " + responseBody);

        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            httpClient.getConnectionManager().shutdown();
        }
    }
}

请注意，Apache HttpClient 在 Android 6.0 及以上版本已被标记为过时，推荐使用 HttpURLConnection 或 OkHttp 来替代。
