Question

我正在尝试使用Google Maps API来计算两个点之间的时间和距离。我的代码相当简单并且可以工作（使用了键盘并且运行顺畅）但是当我部署代码并尝试使用该服务时，机器人给了我错误的答案...

这是代码：

$details = "http://maps.googleapis.com/maps/api/distancematrix/json?origins=Miami&destinations=Miami+Beach&mode=driving&sensor=false";
    $json = file_get_contents($details);
    $arr = json_decode($json, TRUE);
    $distance = $arr[rows][0][elements][0][distance][text];
    $time = $arr[rows][0][elements][0][duration][text];
    $response = "You should be there in $time. Total distance you'll cover: $distance";

$parameters = array('chat_id' => $chatId, "text" => $response);
$parameters["method"] = "sendMessage";
echo json_encode($parameters);

这是机器人回答我的问题：

"You should be there in {. Total distance you'll cover: {";

这是实际的json：

 {
   "destination_addresses" : [ "Miami Beach, Florida, Stati Uniti" ],
   "origin_addresses" : [ "Miami, Florida, Stati Uniti" ],
   "rows" : [
      {
         "elements" : [
            {
               "distance" : {
                  "text" : "15,7 km",
                  "value" : 15745
               },
               "duration" : {
                  "text" : "22 min",
                  "value" : 1322
               },
               "status" : "OK"
            }
         ]
      }
   ],
   "status" : "OK"
}

发生了什么事？！
更新：file_get_contents返回一个字符串。所以我将其解码为PHP数组，但现在机器人甚至没有回答！

$details = "http://maps.googleapis.com/maps/api/distancematrix/json?origins=Miami&destinations=Miami+Beach&mode=driving&sensor=false";
$json = file_get_contents($details);
$JsonObject = json_decode($json);
$distance = $JsonObject->rows[0]->elements[0]->distance->text;
$time = $JsonObject->rows[0]->elements[0]->duration->text;
$response = "You should be there in $time. Total distance you'll cover: $distance";
$chatId = "your telegram id here";
$botToken = "your bot token here";
file_get_contents("https://api.telegram.org/bot$botToken/sendMessage?chat_id=$chatId&text=$response");

这个适用于file_get_contents。

使用PHP的电报机器人 - 回声不起作用
