我构建了一个非常基本的webAPI,在调用时会在屏幕上打印一些json数据。
我用以下
来呼叫apifunction getEnvironmentList(){
$fullUrl = "localhost/serverList/api/rest.php?action=allenvironments&format=json";
$jsonDataRaw = file_get_contents($fullUrl);
return $jsonDataRaw;
}
$jsonData = getEnvironmentList();
echo "<PRE>";
var_dump(json_decode($jsonData, true));
echo "</PRE>";
我收到错误Warning: file_get_contents(localhost/serverList/api/rest.php?action=allenvironments&format=json): failed to open stream: No error in C:\path\inc\getJSONdata.php on line 6
然而,当我访问该网址时,我看到了这个
{"1":{"environmentID":"1","envName":"UAT","envCreatedBy":"mhopkins","envCreatedDtTm":"2013-06-30 00:34:57","envUpdatedBy":"mhopkins","envUpdatedDtTm":"2013-06-30 00:34:57"},"3":{"environmentID":"3","envName":"Platinum","envCreatedBy":"mhopkins","envCreatedDtTm":"2013-06-30 00:37:38","envUpdatedBy":"phpsense","envUpdatedDtTm":"2013-06-30 00:37:38"}}
我真的很困惑为什么代码似乎无法意识到那里有json数据......

您忘记了http
。
$fullUrl = "http://localhost/serverList/api/rest.php?action=allenvironments&format=json";
