php simplexml与spreadshirt api
提问于 2014-04-11 15:52:49
我试图使用Spreadshirt API在他们的平台上创建一个产品，但我遇到了这个奇怪的错误：
Fatal error: Uncaught exception 'Exception' with message 'String could not be parsed as XML' in /home/anarchoi/public_html/test.php:102 Stack trace: #0 /home/anarchoi/public_html/test.php(102): SimpleXMLElement->__construct('') #1 {main} thrown in /home/anarchoi/public_html/test.php on line 102大部分代码都是从他们的wiki上复制过来的，所以我真的不明白为什么它不能工作。
我正在寻找帮助，以了解错误是从哪里来的，以及为什么会发生。

我在实现Spreadshirt时遇到了类似的问题，看起来他们的应用程序接口服务器正在发送(至少是一些)压缩的内容，而不考虑任何Accept-Encoding头文件。你可以通过在字符串被传递给SimpleXMLElement之前使用var_dump来判断它的情况(正如其他人所建议的那样)-如果它是胡言乱语，那么你很可能和我有同样的问题。
将CURLOPT_ENCODING的curl选项设置为空字符串('')修复了对我来说，它“神奇”地打开了string响应(有关更多信息，请参阅man page for curl_setopt() )。
