导入项目运行时，发现org.apache.http.HttpResponse/HttpClient报红

import org.apache.http.Header;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;

最后在网上查找资料，找到方法：

依次点击File--->projectstructure--->

导入如图所示最下面的那个类库就行了
