因此，我使用Google Charts API制作了图表的工作版本，并发布了图表数据/配置，如下所示：
$context = stream_context_create(
array('http' => array(
'method' => 'POST',
'content' => http_build_query($chart))));
fpassthru(fopen($url, 'r', false, $context));
效果很好！但是，当我在我的本地Windows框中检查它并尝试使用Xampp运行时，我收到此错误：
警告： FOPEN（http://chart.apis.google.com/chart?chid=982f36） [function.fopen]：无法打开 stream：HTTP请求失败！ HTTP / 1.0 400错误请求 C：\ XAMPP \ htdocs中\图表\ image.php 在第226行
我看过localbox上的php.ini文件，它在fopen包装器下有这个：
; Whether to allow the treatment of URLs (like http:// or ftp://) as files.
; http://php.net/allow-url-fopen
allow_url_fopen = On
; Whether to allow include/require to open URLs (like http:// or ftp://) as files.
; http://php.net/allow-url-include
allow_url_include = Off
; Define the anonymous ftp password (your email address). PHP's default setting
; for this is empty.
; http://php.net/from
;from="john@doe.com"
; Define the User-Agent string. PHP's default setting for this is empty.
; http://php.net/user-agent
;user_agent="PHP"
; Default timeout for socket based streams (seconds)
; http://php.net/default-socket-timeout
default_socket_timeout = 60
; If your scripts have to deal with files from Macintosh systems,
; or you are running on a Mac and need to deal with files from
; unix or win32 systems, setting this flag will cause PHP to
; automatically detect the EOL character in those files so that
; fgets() and file() will work regardless of the source of the file.
; http://php.net/auto-detect-line-endings
;auto_detect_line_endings = Off
这可能是什么问题？任何建议都有帮助谢谢！

实际上从PHP方面工作得很好。获取该URL并将其粘贴到您的Web浏览器中：
http://chart.apis.google.com/chart?chid=982f36
您将收到来自Google的400 Bad Request错误页面The Chart API request contains no valid parameters。我对Google图表API一无所知，但您似乎无法正确地将参数传递给Google。
