无法在“ file_get_contents（）”中加载cafile流？

Question

我正在尝试从Google地理编码API获取JSON数据。但是，PHP警告显示有关“无法加载cafile流”的一些错误

这是我的代码：

$apiKey  = 'apikey';
$address = urlencode( '1600 Amphitheatre Pkwy, Mountain View, CA 94043' 
);
$url     = "https://maps.googleapis.com/maps/api/geocode/json?address= 
    {$address}key={apiKey}";
$resp    = json_decode( file_get_contents( $url ), true );
echo $url;

$lat    = $resp['results'][0]['geometry']['location']['lat'] ?? '';
$long   = $resp['results'][0]['geometry']['location']['lng'] ?? '';

这是错误：

Answer 1

当您的php.ini文件的curl.cainfo和openssl.cafile配置属性未针对任何有效的证书，这些证书将使您无法与ssl创建连接时，将发生此错误。

例如，使用CURL调用外部服务器的请求时，就会发生这种情况。

您必须从此处的链接中下载casert.pem

并将认证文件放在路径中：

C：\ xampp \ apache \ bin \ cacert.pem

之后，在名为：curl.cainfo和openssl.cafile的配置项上检查php.ini 并进行此配置

例如：

curl.cainfo = "C:\xampp\apache\bin\cacert.pem"
openssl.cafile = "?C:\xampp\apache\bin\cacert.pem"
