Question

我正在构建一个聊天机器人，该聊天机器人从聊天中获取消息，并将其发送到api，该api根据消息生成随机的gif。

axios请求/响应正常工作，但是我需要它来将响应中的URL值存储为外部变量。

然后将使用其他功能在聊天中发送变量/ URL。此函数无法在axios request / then语句中运行，我似乎也无法从其中之一获取要更新的变量。

我对此有些困惑，还没有找到可以满足我需要的方法。任何建议表示赞赏。

How do I return the response from an asynchronous call?并未解决如何从外部获取此消息，因为再次无法从then语句内部运行message函数。

const sentence = context.activity.text.replace('!guggy ', '');

//theoretically this would hold the api response, but this wont update as intended
//var apiResponse;

//api call function
   function postRequest(x) {
    return axios.post('http://exampleurl.here.com/helpapi', {
        "sentence" : x,
        "lang": "ru"
    },{
        headers: {
            "Content-Type":"application/json",
            "apiKey":"example-key-2020202"
                        }
                });
        }

//initiates api call, then logs response or error
postRequest(sentence).then(function(response) {                  
                   console.log(response.data.animated[0].gif.original.url); //this works, returns URL

//attempting to store the same value as external variable doesnt work
apiResponse = response.data.animated[0].gif.original.url; //the variable remains blank when called later

}).catch (function (error) {
    console.log(error);
});


//this has to be run outside of axios/then statement, or it will not work.
//this should take the url passed from the response, and send it as a chat message                     
await context.sendActivity(apiResponse);

这实际上不返回任何错误，并且在服务器上运行。当我需要它时，它只是不返回变量-它的空白。我以为这意味着我只是忽略或误解了一些关键内容。

代码段中的执行顺序为：

致电axios
axios通过网络发送消息。
$message = " <h2>Thank you for Registering.</h2> <p>Your Account:</p> <p>Email: ".$email."</p> <p>Password: ".$_POST['password']."</p> <p>Please click the link below to activate your account.</p> <a href='".$_SERVER['HTTP_HOST']."/activate.php?code=".$code."&user=".$userid."'>Activate Account</a>"; $mail = new PHPMailer(true); try { //Server settings $mail->isSMTP(); $mail->Host = 'smtp.mailtrap.io'; $mail->SMTPAuth = true; $mail->Username = 'e0891ddb9b14a1'; $mail->Password = '373f8f6c93f27d'; $mail->Port = 465; $mail->setFrom('jeraldpunxbot1@gmail.com'); //Recipients $mail->addAddress($email); $mail->addReplyTo('jeraldpunxbot1@gmail.com'); //Content $mail->Subject = 'ShopNow Sign Up'; $mail->Body = $message; $mail->isHTML(true); $mail->send(); unset($_SESSION['firstname']); unset($_SESSION['lastname']); unset($_SESSION['email']); $_SESSION['success'] = 'Account created. Check your email to activate.'; header('location: signup.php'); } catch (Exception $e) { $_SESSION['error'] = 'Message could not be sent. Mailer Error: '.$mail->ErrorInfo; header('location: signup.php'); }用空白的context.sendActivity()调用。
exampleurl.here.com返回axios的答案。
axios调用“ then”子句。
apiResponse被分配了。

您需要适当地等待服务器返回错误，如下所示：

apiResponse

如何将axios响应保存到变量，以在axios外部使用？
