网络与调试配方

这一页把最常一起使用的“联网 + 调试 + 可视化”能力放在一起。

HTTP 客户端探活

http.setTimeout({
  connectTimeout: 5000,
  readTimeout: 10000,
  followRedirects: true
});

const response = http.get("https://httpbin.org/get");
log(`status=${response.statusCode}`);
log(response.body.string());

本地 HTTP 调试服务

httpServer.start({
  port: 18765,
  allowLan: false,
  token: "debug-token"
});

httpServer.get("/debug/state", req => {
  return {
    status: 200,
    mimeType: "application/json; charset=utf-8",
    body: JSON.stringify({
      packageName: lpparam.packageName,
      processName: lpparam.processName,
      activity: String(activity)
    })
  };
});

带查询参数的接口

httpServer.get("/debug/echo", req => {
  const name = req.param("name") || "guest";
  return {
    status: 200,
    mimeType: "application/json; charset=utf-8",
    body: JSON.stringify({
      hello: name
    })
  };
});

MCP Tool 暴露运行时信息

mcpServer.start({
  host: "127.0.0.1",
  port: 5698,
  endpoint: "/mcp",
  token: "secret-token",
  name: "jsxhook-runtime"
});

mcpServer.tool("runtime_state", {
  title: "Runtime State",
  description: "Return package, process and current activity",
  inputSchema: {
    type: "object",
    properties: {}
  }
}, () => {
  return {
    content: [
      {
        type: "text",
        text: JSON.stringify({
          packageName: lpparam.packageName,
          processName: lpparam.processName,
          activity: String(activity)
        }, null, 2)
      }
    ]
  };
});

ImGui 面板配合调试

const state = imgui.reactive({ enabled: false });
const panel = imgui.window("runtime-debug", {
  title: "Runtime Debug",
  width: 360,
  height: 540,
  displayMode: "in_app",
  resizable: true,
  collapsible: true
});

panel.text("包名: " + lpparam.packageName);
panel.text("进程: " + lpparam.processName);
panel.checkbox("启用额外日志", imgui.bind(state, "enabled"));
panel.button("打印 Activity 字段", function () {
  printFields(activity, "\n");
});
panel.show();

Hook + HTTP 联动

const events = [];

hook({
  class: "com.example.target.LoginManager",
  classloader: lpparam.classLoader,
  method: "login",
  params: ["java.lang.String", "java.lang.String"],
  before(it) {
    events.push({
      time: Date.now(),
      args: Array.from(it.args)
    });
  }
});

httpServer.get("/debug/login-events", () => {
  return {
    status: 200,
    mimeType: "application/json; charset=utf-8",
    body: JSON.stringify(events)
  };
});

这种方式很适合在不方便频繁切日志页时，临时把命中的 Hook 结果暴露给浏览器或局域网工具。
