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();
2、post请求，代码如下
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");
