Question

我正在谷歌应用引擎上的php中进行eBay搜索API调用findItemsByKeywords。它在本地工作，而不是GAE。这就是我打电话的方式

$resp = simplexml_load_file($apicall);

我检查了主机提供已启用PHP打开URL，因为文件ini_get('allow_url_fopen')返回1.

只有在GAE上运行时，我才会在$ resp中获取null。

编辑：

这是GAE错误日志中的内容。

我找到了解决方案。我必须使用file_get_contents，如果成功，请执行simplexml_load_string。出于某种原因，GAE不允许我使用simplexml_load_file。

这是有效的代码。

$resp = file_get_contents($apicall);
if($resp){
    $result = simplexml_load_string($resp);       
}

exit(json_encode($result));

从https://developers.google.com/appengine/docs/php/#PHP_Disabled_functions“您还必须在应用程序的启动脚本中的某处调用libxml_disable_entity_loader（false）以启用外部XML实体的加载。”
