在Gravity Forms API中使用Angular拒绝权限

Question

我正在使用Gravity Forms API从Wordpress安装中获取数据的移动应用程序。

不幸的是，我总是收到：

{"status":401,"response":"Permission denied"}

我想，对我如何创建签名的错误，但我无法找到任何东西。任何提示？

您是否尝试过使用了类似的请求

//creating request URL 
$method = "GET"; 
$expires = strtotime("+60 mins"); 
$string_to_sign = sprintf("%s:%s:%s:%s", $api_key, $method, $route, $expires); 
$sig = calculate_signature($string_to_sign, $private_key); 
$url = $api_url . $route . '?api_key=' . $api_key . '&signature=' . $sig . '&expires=' . $expires; 

刚刚返回的URL，看它是否响应200

林，然后使用卷曲查询网址

$curl_response = $this->getCurl($url); 

...

function getCurl($url){ 


     //Initialize cURL. 
     $ch = curl_init(); 

     //Set the URL that you want to GET by using the CURLOPT_URL option. 
     curl_setopt($ch, CURLOPT_URL, $url); 

     //Set CURLOPT_RETURNTRANSFER so that the content is returned as a variable. 
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 

     //Set CURLOPT_FOLLOWLOCATION to true to follow redirects. 
     curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 

     //Execute the request. 
     $data = curl_exec($ch); 

     //Close the cURL handle. 
     curl_close($ch); 

     //Print the data out onto the page. 
     $url_response = json_decode($data); 
     $curl_status = $url_response->status; 
     //forms retrieved successfully 
     return $url_response->response; 
} 

function calculate_signature($string, $private_key) { 
    $hash = hash_hmac("sha1", $string, $private_key, true); 
    $sig = rawurlencode(base64_encode($hash)); 
    return $sig; 
}
