Question

尝试使用Livezilla chatbot脚本与REST API进行通信时遇到麻烦，这两个我都存储在本地PC上。我正在使用与Livezilla chatbot API页面非常相似的代码片段，并且已经对其进行了修改，但是出现一些错误。

27.02.19 11:34:11 :: 1 ERR＃129连接USER API时出错，响应无效：       http://localhost/livezilla/programytalk.php（
      注意：尝试获取非对象的属性“答案”       第11行的C：\ xampp \ htdocs \ livezilla \ programytalk.php       ）在第0行

programytalk.php的代码如下：

<?php
$requestobj = json_decode($_POST["livezilla_user_api_request"]);
$responseNode = array();
$responseNode["ResponseTo"] = "";
$responseNode["Id"] = rand(1111111,9999999);
$responseNode["SearchKB"] = false;
$url = "http://localhost:8989/api/rest/v1.0/ask? question=".rawurlencode($requestobj->Value)."&userid=".$requestobj- 
>VisitorId;
$sdata = json_decode(file_get_contents($url));
$responseNode["Value"] = $sdata->answer;
if(!empty($responseNode["Value"]))

            echo json_encode($responseNode);

?>

这是API响应的JSON格式：

[{"response":{"answer":"Good morning.","question":"hello world","userid":"1234567890"}},200]

Answer 1

通过该API响应，您无需阅读

$responseNode["Value"] = $sdata->answer;

您无需阅读

$responseNode["Value"] = $sdata[0]->response->answer;

因为答案嵌套在响应下方...

提示：只要这样做

$data = json_decode('[{"response":{"answer":"Good morning.","question":"hello world","userid":"1234567890"}},200]');
print_r($data);

输出将是：

Array
(
    [0] => stdClass Object
        (
            [response] => stdClass Object
                (
                    [answer] => Good morning.
                    [question] => hello world
                    [userid] => 1234567890
                )

        )

    [1] => 200
)

Answer 2

请执行此操作

<?php
$requestobj = json_decode($_POST["livezilla_user_api_request"]);
$responseNode = array();
$responseNode["ResponseTo"] = "";
$responseNode["Id"] = rand(1111111,9999999);
$responseNode["SearchKB"] = false;
$url = "http://localhost:8989/api/rest/v1.0/ask? question=".rawurlencode($requestobj->Value)."&userid=".$requestobj- 
>VisitorId;
$sdata = json_decode(file_get_contents($url), true);
$responseNode["Value"] = $sdata->answer;
if(!empty($responseNode["Value"]))

            echo json_encode($responseNode, true);

?>

尝试从API
