我在 winjs.xhr 中检索聊天消息时遇到问题：
function getMessage() {
var time = MESSAGE_RETURNED.unixtime;
if (time == 0) {
time= window.parent.SESSION.unixtime;
}
WinJS.xhr({
url: "http://www.example.com/scripts/default.php?"
+ "action="+ACTIONS.GET_MESSAGE
+ "&username=" + window.parent.SESSION.username
+ "&session_id=" + window.parent.SESSION.session_id
+ "&unixtime=" + time
}).done(
function fulfilled(result) {
console.log("action=" + ACTIONS.GET_MESSAGE
+ "&username=" + window.parent.SESSION.username
+ "&session_id=" + window.parent.SESSION.session_id
+ "&unixtime=" + time);//CHECK INPUTS , ALL GREEN
if (result.status === 200) {
if (result.response.toString.length === 0) {
return false;
}//ALWAYS TRUE;
else {
console.log(JSON.parse(result.response));
}
} else {
document.getElementById("messagelogarea").value += result.status + "\r\n";
}
});
}
我正在尝试从 php 中检索 JSON。但是，使用 WinJS.xhr 时，我返回的响应始终为空。如果将直接链接放在我的浏览器中，我将得到如下结果：（一个包含 3 条聊天消息的数组）
