Question

我已经对change.org API进行了少量API调用，并获得了用户个人资料详细信息和用户创建的请愿列表，现在我需要找到一种使用API登录的方法。但我无法弄清楚为什么它不起作用。

这是获取请愿清单的代码

<?php
$API_KEY = '32cf9810f982f95613cec5cce3154dc83966f2a89111661e6355938ad70b20f6';
$REQUEST_URL = 'https://api.change.org/v1/users/325635554/petitions';
//$PETITION_URL = 'https://www.change.org/p/kasun-pay-your-workers-overtime';
$parameters = array(
    'api_key' => $API_KEY,
    //'petition_url' => $PETITION_URL
);
$query_string = http_build_query($parameters);
$final_request_url = "$REQUEST_URL?$query_string";
$response = file_get_contents($final_request_url);
$json_response = json_decode($response, true);

echo $response; exit;
?>

  ]
}

现在要登录，他们已经提供了此API文档。 https://github.com/change/api_docs/blob/master/v1/documentation/resources/petitions/signatures.md#post-signatures

auth_key    string  The petition authorization key.

所以当我向这个URL发出请求时

https://api.change.org/v1/petitions/3623702/signatures

与post params

api_key=32cf9810f982f95613cec5cce3154dc83966f2a89111661e6355938ad70b20f6&lastName=Hello&email=hello123%40gmail.com&firstName=World&city=Chennai&postal_code=00200&country_code=IN

我收到了这个错误。

{"result":"failure","messages":["authorization key cannot be found or is not granted"]}

API密钥 32cf9810f982f95613cec5cce3154dc83966f2a89111661e6355938ad70b20f6

Answer 1

您需要发送一个rsig变量

$parameters['rsig'] = hash('sha256', $query_string_with_secret_and_auth_key);

change.org登录API调用
