谷歌浏览器插件开发教程8

利用workerman和 谷歌插件通信相结合

1 首先获取groupid 保证插件和inject 同个房间 这样还可以用workerman 相互发送

先插件获得groupid 传递到inject

var groupid;
$('.chongxinlianjie').on('click', function() {
    var wsUri = "ws://111.229.30.162:8282";
    ws = new WebSocket(wsUri);
    //请求服务端后 成功后触发
    ws.onopen = function() {
        groupid = Date.parse(new Date());
        var str2 = {
            "from": "mypanel",
            "tag": 'begin',
            "groupid": groupid,
        };
        var str2 = JSON.stringify(str2);
        ws.send(str2);
        chrome.tabs.query({
            active: true,
            currentWindow: true
        }, function(tab) { //获取当前tab
            //向tab发送请求
            chrome.tabs.sendMessage(tab[0].id, {
                action: "begin",
                groupid: groupid,
            }, function(response) {
                //test.js的数据
            });
        });
    };
    ws.onmessage = function(evt) {
        var data = JSON.parse(evt.data);
        if (data.code == 100) {
            var list = data.data;
            var tag = list.tag;
            var from = list.from;
           
        } else {
            alert(data.msg);
        }
    };
    //我关闭服务的时候 就会触发
    ws.onclose = function(evt) {
        console.log('WebSocketClosed!');
    };
    ws.onerror = function(evt) {
        console.log('WebSocketError!');
    };
})

contentscript只是中间的过渡

function injectCustomJs(jsPath) {
    jsPath = jsPath || 'inject.js';
    var temp = document.createElement('script');
    temp.setAttribute('type', 'text/javascript');
    // 获得的地址类似：chrome-extension://ihcokhadfjfchaeagdoclpnjdiokfakg/js/inject.js
    temp.src = chrome.extension.getURL(jsPath);
    temp.onload = function() {
        // 放在页面不好看，执行完后移除掉
        this.parentNode.removeChild(this);
    };
    document.head.appendChild(temp);
}
 injectCustomJs();
// 
chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {

    window.postMessage({
        cmd: 'sendinject',
        data: request
    }, '*');
});

var groupid;
window.addEventListener("message", function(e) {
    var info = e.data;
    var cmd = info.cmd;
    if (cmd == "sendinject") {
        var data = info.data;
        var action = data.action;
        if (action == "begin") {
            console.log('inject开始初始化');
            groupid = data.groupid;
            var wsUri = "ws://111.229.30.162:8282";
            ws = new WebSocket(wsUri);
            //请求服务端后 成功后触发
            ws.onopen = function() {
                var str2 = {
                    "from": "inject",
                    "tag": 'begin',
                    "groupid": groupid,
                };
                var str2 = JSON.stringify(str2);
                ws.send(str2);
              
            };
            ws.onmessage = function(evt) {
                var data = JSON.parse(evt.data);
                if (data.code == 100) {
                    var list = data.data;
                    var from = list.from;
                    var tag = list.tag;
                    var title = list.title;
                    if (from == "mypanel") {
                        console.log('injectjs收到的数据');
                        console.log(list);
                      
                    }
                } else {
                    alert(data.msg);
                }
            };
            //我关闭服务的时候 就会触发
            ws.onclose = function(evt) {
                console.log('WebSocketClosed!');
            };
            ws.onerror = function(evt) {
                console.log('WebSocketError!');
            };
        }
    }
}, false);

上面是injectjs 

最后发现workerman代码 

 public static function onMessage($client_id, $message)
    {
        $data    = json_decode($message, 'true');
        $tag     = $data['tag'];
        $from    = $data['from'];
        $groupid = $data['groupid'];
        $fid     = $client_id;

        if ($tag == 'begin') {
            $time       = time();
            $insertdata = array('laizi' => $from, 'fid' => $fid, 'groupid' => $groupid, 'time' => $time);
            commoninsertinfo($insertdata, 'cocoschajian');
        } else {
            $sql = 'select fid from cocoschajian where groupid=? and laizi=? limit 1';
            if ($from == 'mypanel') {
                $to = 'inject';
            } else {
                $to = 'mypanel';
            }
            $fid = commongetinfo($sql, array($groupid, $to))[0]['fid'];
            if (empty($fid)) {
                $data = json_encode(array('code' => 323, 'msg' => '服务器错误 请重新链接'));
            } else {
                $data = json_encode(array('code' => 100, 'msg' => '发送成功', 'data' => $data));
            }

            Gateway::sendToClient($fid, $data);
        }

        // print_r($data);
        // 向所有人发送

    }

这个后台代码只是个桥梁
