Java使用x-www-form-urlencoded發(fā)請(qǐng)求方式
更新時(shí)間：2024年09月29日 08:58:21 作者：hogenlaw
在開發(fā)中經(jīng)常使用JSON格式,但遇到x-www-form-urlencoded格式時(shí),可以通過(guò)重新封裝處理,POSTMan和APIpost工具中對(duì)此編碼的稱呼不同,分別是x-www-form-urlencoded和urlencoded,分享這些經(jīng)驗(yàn)希望對(duì)他人有所幫助
Java使用x-www-form-urlencoded發(fā)請(qǐng)求
平常在開發(fā)過(guò)程中用的最多的就是JSON格式，請(qǐng)求編碼就是 application/json
但偏偏有些接口是 x-www-form-urlencoded
怎么辦呢
重新封裝嘍?。。?！
- 在POSTMan工具是叫 x-www-form-urlencoded
- 在 APIpost工具中是叫 urlencoded
Map<String, String> request = new HashMap<>();
request.put("username", "xxx");
request.put("password", "xxx");
String result = HttpRequestUtil.post(request, "http://xxxx", new HashMap<String, String>(), "application/x-www-form-urlencoded");
