Question

您好我有一个curl类，它将帖子发送到远程服务器。在该服务器上，我从数据库获取数据并将其回显。收集数据但是我发送curl服务器得不到数据。这是我的代码：

$ch = curl_init();

self::$CURL_OPTS[CURLOPT_URL] = $this->url;
self::$CURL_OPTS[CURLOPT_POST] = true;
self::$CURL_OPTS[CURLOPT_POSTFIELDS] = $this->get_data();

curl_setopt_array($ch, self::$CURL_OPTS);

$result = curl_exec($ch);

curl_close($ch);

echo $result;

尽管它将数据发送到远程服务器，但没有任何回声。

这是一个curl类，所以如果你需要更多代码来帮助我，请告诉我。

EDIT ********************* 我有它，它仍然无法正常工作。这是我的班级。

Answer 1

如果您希望将数据作为curl_exec的结果，则需要将CURLOPT_RETURNTRANSFER选项设置为true。

来自文档：

CURLOPT_RETURNTRANSFER    TRUE to return the transfer as
                          a string of the return value of
                          curl_exec() instead of outputting
                          it out directly.

编辑：查看您的curl类，您有以下代码：

protected static $CURL_OPTS = array(
    CURLOPT_CONNECTTIMEOUT => 10,
    CURLOPT_RETURNTRANSFER => 0,       // this line ensures that you do NOT get the data back
    CURLOPT_TIMEOUT        => 60,
    CURLOPT_POST           => false,
    CURLOPT_HTTPHEADER     => array()
);

将其更改为

protected static $CURL_OPTS = array(
    CURLOPT_CONNECTTIMEOUT => 10,
    CURLOPT_RETURNTRANSFER => 1,       // this line ensures that you do get the data back
    CURLOPT_TIMEOUT        => 60,
    CURLOPT_POST           => false,
    CURLOPT_HTTPHEADER     => array()
);

Answer 2

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

PHP curl post工作但不返回数据
