我已经阅读了很多有关此问题的Stack Overflow问题，但我仍然无法解决这个问题。 我从一个我无法控制的服务的webhook中获取以下JSON。我将数据读入PHP变量，如下所示：
$postData = file_get_contents('php://input');
我将$ postData输出到日志文件以查看POST请求的内容，如下所示：

我通过jsonlint.com运行上面的JSON，它有效。我尝试使用一些其他SO问题中建议的substr（$ postData，3）来摆脱字符串上的BOM编码，但这只是切断了我的JSON字符串的前3个字符。
var_dump(json_decode($postData,true) );只返回空白。我可以看到，通过将json_decode($postData,true)输出到变量然后记录变量来创建数组，但它完全为空。 json_last_error()返回0，并且php error_log中没有显示警告或错误。
我不知道为什么JSON字符串没有正确地进入带有json_decode的数组...以及为什么json_last_error（）将为0并且数组仍为空...任何帮助将不胜感激。< / p>
