PHP Curl文件附件;自定義內容類型標題

Question

我必須發佈一個文件到一個服務器旁邊有一些post params。我從這個服務器管理員處收到的文檔顯示了一個示例，說明發布請求應該看起來像什麼（*請注意POST的自定義內容類型「multipart/x-api-remote-integration」）：

POST /gateway/remote_send HTTP/1.0 

Content-Type: multipart/x-api-remote-integration; boundary=ABC1234 

Content-Length: 323 

--ABC1234 

Content-Type: application/x-www-form-urlencoded 

profile_name=username&profile_pw=password1234&attached_type=action_1 

--ABC1234 

Content-Type: text/csv 

Content-Disposition: attachment; filename="attachment.csv" 
row1 
row2 
row3 

--ABC1234-- 

下面是PHP代碼：

<?php 
function post(){ 
    $base_api_url = "https://hostserver.com/gateway/remote_send"; 

    $filename = realpath("/home/username/tests/test1234qwerty.csv"); 

    $payload['profile_name'] = "username"; 
    $payload['profile_pw'] = 'password1234'; 
    $payload['attached_type'] = 'action_1'; 
    $payload['filename'] = "@" . $filename . ";type=text/csv;"; 

    $curl_options = array(
     CURLOPT_URL => $base_api_url, 
     CURLOPT_POST => true, 
     CURLOPT_POSTFIELDS => http_build_query($payload), 
     CURLOPT_HTTP_VERSION => 1.0, 
     CURLOPT_RETURNTRANSFER => true, 
     CURLOPT_VERBOSE => true, 
     CURLOPT_HEADER => false, 
    ); 

    $curl = curl_init(); 
    curl_setopt_array($curl, $curl_options); 
    $result = curl_exec($curl); 
    curl_close ($curl); 
    echo $result; 
    } 

post(); 

從什麼我收到從服務器返回，似乎正在被正確地接收到請求領域。但是，這是沒有收到的文件。我不確定我做錯了什麼。任何輸入是不勝感激。

我知道用戶名和PW數據被讀取服務器正確的，因爲我有錯誤的信息測試，並獲得證書錯誤信息。

當您告訴cURL上傳文件時，Content-Type標題會自動設置爲multipart/form-data。對於文檔中的請求，您必須手動上傳文件。

<?php 
$url  = 'https://hostserver.com/gateway/remote_send'; 
$payload = array(
    'profile_name' => 'username', 
    'profile_pw' => 'password1234', 
    'attached_type' => 'action_1' 
); 
$file = realpath('/home/username/tests/test1234qwerty.csv'); 

// build multipart 
$payload = http_build_query($payload); 
$params = "--ABC1234\r\n" 
    . "Content-Type: application/x-www-form-urlencoded\r\n" 
    . "\r\n" 
    . $payload . "\r\n" 
    . "--ABC1234\r\n" 
    . "Content-Type: text/csv\r\n" 
    . "Content-Disposition: attachment; filename=\"attachment.csv\"\r\n" 
    . "\r\n" 
    . file_get_contents($file) . "\r\n" 
    . "--ABC1234--"; 

$first_newline  = strpos($params, "\r\n"); 
$multipart_boundary = substr($params, 2, $first_newline - 2); 
$request_headers = array(); 
$request_headers[] = 'Content-Length: ' . strlen($params); 
$request_headers[] = 'Content-Type: multipart/x-api-remote-integration; boundary=' 
    . $multipart_boundary; 

// send the request now 

$ch = curl_init($url); 
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $params); 
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0); 
curl_setopt($ch, CURLOPT_HTTPHEADER, $request_headers); 

$reply = curl_exec($ch); 

這是否行得通？
