没有php-CUrl的结果

Question

我对谷歌地理编码API有个问题。当我转到与api调用对应的url时，我想要钥匙]，我有两个结果。当我通过php-CUrl问它时，我有一个“没有结果”的回答。在300个不同的地址，我有一些喜欢它(最多15个)。我不知道为什么。

我试了几样东西:经典卷曲

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$res = curl_exec($ch);

卷曲类(https://github.com/php-curl-class/php-curl-class)：

$curl->setUserAgent('Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.135 Safari/537.36');
$curl->setHeader('pragma', 'no-cache');
$curl->setHeader('accept-encoding', 'gzip, deflate, sdch');
$curl->setHeader('accept-langage', 'fr-FR,fr;q=0.8,en;q=0.6,en-US;q=0.4');
$curl->setHeader('accept', 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8');
$curl->setHeader('cache-control', 'no-cache');
$curl->setHeader('authority', 'maps.googleapis.com');
$curl->get($url);

有和没有用户代理/头。谢谢!

Answer 1

我建议总是在查询字符串的末尾添加一个国家代码，这样google就知道应该在哪里查找，而不是根据参数/请求头来猜测。

注意以下之间的区别：

$result = file_get_contents('https://maps.googleapis.com/maps/api/geocode/json?address=6+QUAI+DE+LORIENT+94569+RUNGIS+CEDEX');
var_dump(json_decode($result));

$result = file_get_contents('https://maps.googleapis.com/maps/api/geocode/json?address=6+QUAI+DE+LORIENT+94569+RUNGIS+CEDEX,FR');
var_dump(json_decode($result));

第一个没有结果，第二个没有结果。

给出的cURL代码的问题是，您没有为请求设置足够的选项。您正在尝试从https地址检索，但是您的curl请求不承认这一点。

您需要在系统的某个地方拥有一个cacert.pem的副本，并使用cainfo选项(Cainfo)在curl中引用该副本。你可以在这里下载cacert.pem

然后，您需要在您的卷发配置中引用这一点。

    /* I would NOT recommend storing cacert in your document root but this is just as an example. */

    $cacert=$_SERVER['DOCUMENT_ROOT'].'/cacert.pem';
    if( !file_exists( realpath( $cacert ) ) exit('cant find certificate bundle');


    $url='https://maps.googleapis.com/maps/api/geocode/json?address=dundee,scotland';

    $curl=curl_init();
    curl_setopt( $curl, CURLOPT_URL, $url );

    if( parse_url( $url,PHP_URL_SCHEME )=='https' ){
        curl_setopt( $curl, CURLOPT_SSL_VERIFYPEER, FALSE );
        curl_setopt( $curl, CURLOPT_SSL_VERIFYHOST, 2 );
        curl_setopt( $curl, CURLOPT_CAINFO, realpath( $cacert ) );
    }
    curl_setopt( $curl, CURLOPT_AUTOREFERER, TRUE );
    curl_setopt( $curl, CURLOPT_FOLLOWLOCATION, TRUE );
    curl_setopt( $curl, CURLOPT_FRESH_CONNECT, TRUE );
    curl_setopt( $curl, CURLOPT_FORBID_REUSE, TRUE );
    curl_setopt( $curl, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1 );
    curl_setopt( $curl, CURLOPT_CLOSEPOLICY, CURLCLOSEPOLICY_OLDEST );
    curl_setopt( $curl, CURLOPT_MAXCONNECTS, 1 );
    curl_setopt( $curl, CURLOPT_FAILONERROR, FALSE );
    curl_setopt( $curl, CURLOPT_HEADER, FALSE );
    curl_setopt( $curl, CURLOPT_RETURNTRANSFER, TRUE );
    curl_setopt( $curl, CURLOPT_CONNECTTIMEOUT, 15 );
    curl_setopt( $curl, CURLOPT_TIMEOUT, 90 );
    curl_setopt( $curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.135 Safari/537.36' );
    curl_setopt( $curl, CURLINFO_HEADER_OUT, FALSE );
    curl_setopt( $curl, CURLOPT_NOBODY, TRUE );

    $payload=array_filter( array(
            'response'  =>  curl_exec( $curl ),
            'info'          =>  curl_getinfo( $curl ),
            'errors'        =>  curl_error( $curl )
        ) 
    );
    curl_close( $curl );
    print_r( $payload );
