php - 将CURL命令转换为CURL php

Question

我正在尝试通过批量API将文档添加到 flex 搜索索引中。我的CURL查询在命令行上工作正常，我将其转换为PHP。

当我尝试运行PHP代码时，什么都没有发生。 flex 搜索中都不会将文档添加到索引中，也不会出现任何错误。

CURL查询:

curl -H "Content-Type:application/json" -XPOST "http://localhost:9200/inven/default/_bulk?pretty" --data-binary "@file_name.json"

PHP查询:

 $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, 'http://localhost:9200/inven/default/_bulk?pretty');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $post = array(
        'file' => '@' .realpath('file_name.json')
    );
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
    curl_setopt($ch, CURLOPT_POST, 1);

    $headers = array();
    $headers[] = 'Content-Type: application/json';
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

    $result = curl_exec($ch);
    if (curl_errno($ch)) {
        echo 'Error:' . curl_error($ch);
    }
    curl_close ($ch);

我还设置了 ini_set('max_execution_time', 0);，以防万一它超时了。
可能是什么问题？

您没有发送实际的文件内容，而只是发送文件名作为字符串。试试这个:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://localhost:9200/inven/default/_bulk?pretty');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1 );

// The line below assumes the file_name.json is located in the same directory
// with this script, if not change the path to the file with the correct one.
curl_setopt($ch, CURLOPT_POSTFIELDS, file_get_contents('file_name.json') );
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));

$result = curl_exec($ch);

if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
}
curl_close ($ch);
