java - 如何发送带有正文的 HTTP GET？

Question

老板要我们发送一个HTTP GET，正文中有参数。我不知道如何使用 org.apache.commons.httpclient.methods.GetMethod 或 java.net.HttpURLConnection; 来做到这一点。

GetMethod 似乎不接受任何参数，我不确定如何为此使用 HttpURLConnection。

您可以扩展 HttpEntityEnclosingRequestBase 类以覆盖继承的 org.apache.http.client.methods.HttpRequestBase.getMethod()但事实上 HTTP GET 不支持正文请求，也许你会遇到一些 HTTP 服务器的问题，使用风险自负:)

public class MyHttpGetWithEntity extends HttpEntityEnclosingRequestBase {
    public final static String GET_METHOD = "GET";
    
    public MyHttpGetWithEntity(final URI uri) {
        super();
        setURI(uri);
    }
    
    public MyHttpGetWithEntity(final String uri) {
        super();
        setURI(URI.create(uri));
    }

    @Override
    public String getMethod() {
        return GET_METHOD;
    }
}

then


    import org.apache.commons.io.IOUtils;
    import org.apache.http.HttpResponse;
    import org.apache.http.client.HttpClient;
    import org.apache.http.entity.StringEntity;
    import org.apache.http.impl.client.DefaultHttpClient;
    
    public class HttpEntityGet {
    
        public static void main(String[] args) {
            
            try {
                HttpClient client = new DefaultHttpClient();
                MyHttpGetWithEntity e = new MyHttpGetWithEntity("http://....");
                e.setEntity(new StringEntity("mystringentity"));
                HttpResponse response = client.execute(e);
                System.out.println(IOUtils.toString(response.getEntity().getContent()));
            } catch (Exception e) {
                System.err.println(e);
            }
        }
    }
