使用HttpGet发送formdata格式数据

[wangxg]

今天对接第三方接口，遇到个奇怪的方式，要求使用HttpGet发送FormData，但是吧使用HttpGet发送FormData格式的数据不是标准做法，因为HttpGet通常用于获取资源，它的设计不包括请求体（request body）。当然人家既然弄出这样的接口，就表示一般是可以实现的，
以下是实现源码

• HttpGetWithBody继承HttpEntityEnclosingRequestBase ，而HttpEntityEnclosingRequestBase支持携带body
  

代码:

import org.apache.http.client.methods.HttpEntityEnclosingRequestBase;

import java.net.URI;

/**
* httpget带body
*
* @author 1dream.fun
* @since 2024/10/15 14:54
*/
public class HttpGetWithBody extends HttpEntityEnclosingRequestBase {
    public static final String METHOD_NAME = "GET";
    HttpGetWithBody(final String uri) {
        super();
        setURI(URI.create(uri));
    }

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

• 接口实现，具体以实际需求进行改动
  

代码:

import org.apache.http.client.entity.EntityBuilder;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
    /**
     * 获取form请求结果
     * @param url 地址
     * @param headers 请求头
     * @param body 请求form参数
     * @date 2024/10/18 11:08
     * @return java.lang.String
     */
    private static String getWithForm(String url, Map<String,String> headers,Map<String,Object> body) throws IOException {
        HttpGetWithBody httpGet = new HttpGetWithBody(url);
        headers.forEach(httpGet::setHeader);
        final MultipartEntityBuilder multipartEntityBuilder = MultipartEntityBuilder.create();
        body.forEach((k,v)-> multipartEntityBuilder.addTextBody(k, Optional.ofNullable(v).map(Object::toString).orElse("")));
        httpGet.setEntity(multipartEntityBuilder.build());
        return EntityUtils.toString(HttpClients.createDefault().execute(httpGet).getEntity());
    }

以上就是本次实现 使用HttpGet发送formdata格式数据的解决办法
