有大佬能帮忙看看 Java 怎么获取这个网址返回的数据吗？ https://steamcommunity.com/inventory/76561198426206369/730/2?l=chinese&count=5000

steam 有现成的 api 。多看看文档

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

java.net.SocketException: Connection reset

@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

你的 proxy 不对呗 指不定是 socks5 被你当成 http 的调了
