    如果你的连返回的 JSON 数据都拿不到报超时的话,是因为 steamcommunity.com 是 Steam 社区的地址,在国内是没法直接访问的,之前我做毕设的时候就遇到了这个问题,如果你要在 Java 项目中访问只能走代理分流或者用国外服务器反代。

    为什么我开 fq 软件后浏览器可以并收到返回的获取数据,但是在 java 项目中连接超时呢?

    #3 你的 java client 也需要设置 proxy 的

    @wzx155 楼上的方法我不清楚具体做法,我当时是确定本地代理在哪个端口上,比方说如果在 1080 端口的话,就在访问接口的那段 Java 代码里加上代理信息 {"http:":"127.0.0.1:1080", "https:":"127.0.0.1:1080"} 这样最后打出的 JAR 包在本机跑也不会有问题。

    大佬我买了个国外的 ip 设置了代理,连接到是不超时了,现在又 Connection reset 了

    @wzx155 老代码也找不到了不记得当时怎么写的了,没有响应码的话没法确定是哪里的问题,但是一般来说都是 Steam 强制 HTTP 跳转到 HTTPS 了,拿到响应代码看看呢
