“翻译”cURL到PHP

Question

我很难在PHP中使用cURL。我不确定我需要做什么来“翻译”这个：

curl -X POST -u "{username}:{password}" --header "Content-Type: application/json" --data-binary @profile.json "https://gateway.watsonplatform.net/personality-insights/api/v3/profile?version=2016-10-20&consumption_preferences=true&raw_scores=true"

到PHP中去执行它。

到目前为止，这就是我所知道的全部，但我觉得我还远远没有接近：

$url2 = 'https://watson-api-explorer.mybluemix.net/personality-insights/api/v3/profile?raw_scores=false&csv_headers=false&consumption_preferences=true&version=2017-02-01';
$request_headers = array();
$request_headers[] = 'Accept: application/json';
$request_headers[] = 'Content-Type: text/plain';
$request_headers[] = 'Content-Language: en';
$request_headers[] = 'Accept-Language: en';

$ch2 = curl_init( $url2 );
curl_setopt( $ch2, CURLOPT_POST, 1);
curl_setopt( $ch2, CURLOPT_POSTFIELDS, $myvars2);
curl_setopt( $ch2, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt( $ch2, CURLOPT_HEADER, $request_headers);
curl_setopt( $ch2, CURLOPT_RETURNTRANSFER, 1);
$response2 = curl_exec( $ch2 );
var_dump($response2);

看起来您只是错过了身份验证部分：

curl_setopt( $ch2, CURLOPT_USERPWD, "yourUsername:yourPassword");

查看manual。同样，你也可以这样做，这样会更容易一些：

curl_setopt_array( $ch2, array(
    CURLOPT_POST => 1,
    CURLOPT_POSTFIELDS => $myvars2,
    CURLOPT_FOLLOWLOCATION => 1,
    CURLOPT_HEADER => $request_headers,
    CURLOPT_RETURNTRANSFER => 1,
    CURLOPT_USERPWD => 'yourUsername:yourPassword'
);
