was8.5调用HttpPost使用httpClient-4.5.1.jar与was原生自带jar包冲突

一、更换jar方法。

1、将httpClient4.5.1.jar包去掉，更换使用commons-httpclient-3.1.jar。

2、更换方法，将HttpPost类转换为PostMethod类。

3、使用httpClient4.5.1的类

finally

4、使用commons-httpclient-3.1.jar的类（以json字符串为例传输数据）

 

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.PostMethod;
import org.apache.commons.httpclient.methods.RequestEntity;
import org.apache.commons.httpclient.methods.StringRequestEntity;

public class testHttp {
public static String sendHttpReq(String url,String params) throws Exception {

String encode = "UTF-8";
HttpClient client = new HttpClient();
PostMethod method = new PostMethod(url);
RequestEntity se = new StringRequestEntity (params ,"application/json" ,"UTF-8");
method.setRequestEntity(se);
method.setRequestHeader("Content-Type","application/json");
client.executeMethod(method);
String aa=new String(method.getResponseBody(), "UTF-8");
System.out.println(aa);
return new String(method.getResponseBody(), encode);
}

 

}
