研究了一下cocos2d-js的http网络请求，很简单

1、get请求，代码如下

var xhr = cc.loader.getXMLHttpRequest();
        var statusGetLabel = new cc.LabelTTF("Status:", "Thonburi", 18);
        this.addChild(statusGetLabel, 1);
        statusGetLabel.x = winSize.width / 2;
        statusGetLabel.y = winSize.height - 100;
        statusGetLabel.setString("Status: Send Get Request to httpbin.org");
        //set arguments with <URL>?xxx=xxx&yyy=yyy
        xhr.open("GET", "http://httpbin.org/get?show_env=1", true);

        xhr.onreadystatechange = function () {
            if (xhr.readyState == 4 && (xhr.status >= 200 && xhr.status <= 207)) {
                var httpStatus = xhr.statusText;
                var response = xhr.responseText.substring(0, 100) + "...";
                var responseLabel = new cc.LabelTTF("GET Response (100 chars): \n" + response, "Thonburi", 16);
                that.addChild(responseLabel, 1);
                responseLabel.anchorX = 0;
                responseLabel.anchorY = 1;
                responseLabel.textAlign = cc.TEXT_ALIGNMENT_LEFT;

                responseLabel.x = 10;
                responseLabel.y = winSize.height / 2;
                statusGetLabel.setString("Status: Got GET response! " + httpStatus);
            }
        };
        xhr.send();

var xhr = cc.loader.getXMLHttpRequest();
        var statusPostLabel = new cc.LabelTTF("Status:", "Thonburi", 18);
        this.addChild(statusPostLabel, 1);

        statusPostLabel.x = winSize.width / 2;

        statusPostLabel.y = winSize.height - 140;
        statusPostLabel.setString("Status: Send Post Request to httpbin.org with plain text");

        xhr.open("POST", "http://httpbin.org/post");
        //set Content-type "text/plain;charset=UTF-8" to post plain text
        xhr.setRequestHeader("Content-Type","text/plain;charset=UTF-8");
        xhr.onreadystatechange = function () {
            if (xhr.readyState == 4 && (xhr.status >= 200 && xhr.status <= 207)) {
                var httpStatus = xhr.statusText;
                var response = xhr.responseText.substring(0, 100) + "...";
                var responseLabel = new cc.LabelTTF("POST Response (100 chars):  \n" + response, "Thonburi", 16);
                that.addChild(responseLabel, 1);
                responseLabel.anchorX = 0;
                responseLabel.anchorY = 1;
                responseLabel.textAlign = cc.TEXT_ALIGNMENT_LEFT;

                responseLabel.x = winSize.width / 10 * 3;
                responseLabel.y = winSize.height / 2;
                statusPostLabel.setString("Status: Got POST response! " + httpStatus);
            }
        };
        xhr.send("plain text message");
