在纯 java 中调用 rest 调用
Calling rest calls in pure java
我这里有一个小问题，我想进行 restfull post 调用，它的响应是一个带有会话 ID 的 cookie，然后我用一些不同的 url 并使用该 cookie 作为参考，否则如果我不使用该 cookie，我的 get 请求将被拒绝，因为我将不是授权用户，因此可以使用 curl 命令和命令轻松实现我正在使用
curl -X POST 'http://localhost:8465/myapp/j_spring_security_check?j_username=username&j_password=password' -v -c /tmp/localcookie.txt
curl -H "Content-Type: application/json" -X GET http://localhost:8465/myapp/entity/v1/loadLogs/3056 -b /tmp/ludwigcookie.txt > /tmp/somejson.json
如果您在上面的 curl 命令中看到我正在使用 post curl 创建 cookie 并使用该 cookie 我正在 运行ning get 请求我将结果存储在 json 文件中。所以，我的问题是，在普通 java 中调用 post 请求，然后从响应中创建一个 cookie，然后再次使用该 cookie 调用 Get 方法并从中创建 json 对象.我尝试使用 URL 和 httpURLconnection 但无法成功，我们将不胜感激。

如果你看到上面那个，我在 txt 文件中成功生成了 cookie，文本文件中的结果如下所示

但是当我 运行 @shubham 提到的 java 代码时，它给了我一个普通的 html 代码而不是 jsession
Java 代码响应如下所示
