400 錯誤，由於url編碼問題

在url拼接中文時加上這一句 URLEncoder.encode("黃鶴樓","utf-8")

import java.io.UnsupportedEncodingException; import java.net.URLEncoder; import java.util.List;

import com.alibaba.fastjson.JSON;

import test.test.entity.Result2; import test.test.entity.ResultMsg2;

public class Shiming { static String result = null; static ResultMsg2 result1=null; public static void main(String[] args) { B.test1(); }

public static void test1(String url) throws UnsupportedEncodingException {
	String httpurl ="https://api.apiopen.top/searchPoetry?name="+URLEncoder.encode(url,"utf-8");; // 接口名
	
	String params = "&a=1&b=2";// 如此拼接便可
	H a = new H();
	result = a.httpRequestUtils(httpurl, params);
	ResultMsg2 resultMsg = JSON.parseObject(result, ResultMsg2.class);
	//System.out.println("resultMsg:" + resultMsg); // OK
	result1=resultMsg;
	List<Result2>  a1= resultMsg.getResult();
	
	for(int i=0;i<a1.size();i++) {
		System.out.println(a1.get(i).getTitle());
		System.out.println(a1.get(i).getAuthors());
		System.out.println(a1.get(i).getContent());
	}
	
}

//返回result public ResultMsg2 Result() { return result1; } }
