string - 从网页读取 REST API 端点 - 使用 JAVA

问题描述

我正在实现一个 OIDC 客户端，我想从该网页读取其余端点。

https://login.bbmri-eric.eu/oidc/.well-known/openid-configuration

例如，我的应用程序应该有密钥authorization_endpoint，它应该从上面提到的 url 中读取这个密钥的值。

有没有一种方法/库可以在没有太多字符串检查的情况下从这样的网页中读取？

标签： stringrestopenid-connect

解决方案

如果你https://login.bbmri-eric.eu/oidc/.well-known/openid-configuration在浏览器中点击，你会得到一个 json，如下所示。正如评论中提到的，您所需要的只是下面的代码。

如何在 java 中读取 json - 许多选项之一是包含 Apache Commons IOUtils 和 json.org 库（下载 maven 依赖项）。

JSONObject jsonObject = new JSONObject(IOUtils.toString(new URL("https://login.bbmri-eric.eu/oidc/.well-known/openid-configuration"), Charset.forName("UTF-8")));

如果下面的 JSON，现在这个 jsonObject 是 java 表示。我希望你知道如何使用 java 对象。如果您没有阅读本指南或查看此主题链接
