我在这里使用 API:http: //developers.livechatinc.com/rest-api/# !chats
我正在尝试解析通过我的 LiveChat 服务提供商返回的数据。以下是成功调用 API 后返回的内容:
object(stdClass)#3 (3) {
["chats"]=>
array(1) {
[0]=>
object(stdClass)#4 (17) {
["type"]=>
string(4) "chat"
["id"]=>
string(10) "MUQM3RLYBV"
["visitor_id"]=>
string(22) "S1381706997.d8b6736611"
["agents"]=>
array(1) {
[0]=>
object(stdClass)#5 (2) {
["display_name"]=>
string(17) "Display Name"
["email"]=>
string(30) "Email"
}
}
["supervisors"]=>
array(0) {
}
["rate"]=>
string(10) "rated_good"
["duration"]=>
int(50)
["group"]=>
array(1) {
[0]=>
int(1)
}
["started"]=>
string(25) "Sun, 10/13/13 06:30:39 pm"
["pending"]=>
bool(false)
["tags"]=>
array(0) {
}
["prechat_survey"]=>
array(3) {
[0]=>
object(stdClass)#10 (3) {
["key"]=>
string(5) "Name:"
["value"]=>
string(12) "Demo Name"
["id"]=>
string(18) "138133839826202879"
}
[1]=>
object(stdClass)#11 (3) {
["key"]=>
string(7) "E-mail:"
["value"]=>
string(14) "demo@gmail.com"
["id"]=>
string(18) "138133839826305342"
}
[2]=>

string(17) "Choose a Subject:"
["value"]=>
string(4) "Math"
["id"]=>
string(18) "138133839826304607"
}
}
["started_timestamp"]=>
int(1381707039)
["ended_timestamp"]=>
int(1381707089)
["ended"]=>
string(25) "Sun, 10/13/13 06:31:29 pm"
}
}
["total"]=>

}
我很难从返回的数据中获取我需要获取的某些数据。这是我一直在使用的代码,但它不起作用:
<?php
require_once('lib/LiveChat_API.php');
try {
$LiveChatAPI = new LiveChat_API();
$output = $LiveChatAPI->chats->get();
$array = json_decode($output, true); //Saves the returned JSON object as a multi-dimensional array
echo $array['prechat_survey']['E-mail'];
} catch (Exception $e) {
die($e->getCode().' '.$e->getMessage());
}
?>
例如,我如何获得“prechat_survey”下“E-mail”的值?
