1.首先创建一个URL对象并指定请求的URL地址。 URLurl=newURL("http://example/api");2.调用URL对象的openConnection()方法创建HttpURLConnection对象。 HttpURL5.Performnetworkrequest:privatevoiddoHttpRequest(){尝试{URLurl=newURL("http://192.168.xxx.xxx:8080/xxx/login");HttpURLConnectionconn=(HttpURLConnection)

Stringurl="https://xxx-yourrequestaddress";URLserverUrl=newURL(url);HttpURLConnectionconn=(HttpURLConnection)serverUrl.openConnection();//设置是否输出到连接，因为//Postrequesturl与get的区别在于不需要带参数URLpostUrl=newURL(POST_URL);//打开连接HttpURLConnectionconnection=( HttpURLConnection)postUrl
