jsp开发中apache-httpclient 用户验证的实例详解
前言:
在微服务框架之外的系统中,我们经常会遇到使用httpclient进行接口调用的问题,除了进行白名单的设置,很多时候我们需要在接口调用的时候需要身份认证。翻了一下官方文档,解决方法很多,但是都不太符合实际业务场景,这里提供一种简单粗暴的解决方法。
解决方法:利用请求头,将验证信息保存起来。
实现代码:
public class httpclientutils {
protected static final logger log = loggerfactory.getlogger(httpclientutils.class);
private static final string authenkey = "authorization";
private static final string basickey = "basic ";
public static string getconnect(string url,string username,string password) {
closeablehttpresponse response = null;
closeablehttpclient client = httpclients.createdefault();
httpget httpget = new httpget(url);
base64 token = new base64();
string authenticationencoding = token.encodeasstring(new string(username + ":" + password).getbytes());
httpget.setheader(authenkey, basickey + authenticationencoding);
string responsecontent = "";
try {
response = client.execute(httpget);
httpentity entity = response.getentity();
responsecontent = entityutils.tostring(entity, "utf-8");
} catch (ioexception e) {
log.error(e.tostring());
} finally {
if (response != null) {
try {
response.close();
} catch (ioexception e) {
log.error(e.tostring());
}
}
if (client != null) {
try {
client.close();
} catch (ioexception e) {
log.error(e.tostring());
}
}
}
return responsecontent;
}
}
