如何添加使用列表中的聯繫人（發送網格）PHP API

Question

我試圖使用PHP API添加在列表中的聯繫人，但其拋出波紋管段錯誤

字符串（51）「{」錯誤「： {「message」：「請求正文無效」}]}「{」email「：」hello@test.com「，」first_name「：」hh「，」last_name「：」User「}

我正在使用波紋管代碼片段：

$url = 'https://api.sendgrid.com/v3'; 
$request = $url.'/contactdb/lists/12345/recipients'; //12345 is list_id 
$params = array(
'email' => 'hello@test.com', 
'first_name' => 'hh', 
'last_name' => 'User' 
); 
$json_post_fields = json_encode($params); 
// Generate curl request 
$ch = curl_init(); 
$headers = 
array("Content-Type: application/json", 
"Authorization: Bearer SG.XXXXXXXX"); 
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_URL, $request); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_TIMEOUT, 60); 
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); 
// Apply the JSON to our curl call 
curl_setopt($ch, CURLOPT_POSTFIELDS, $json_post_fields); 
$data = curl_exec($ch); 
if (curl_errno($ch)) { 
print "Error: " . curl_error($ch); 
} else { 
// Show me the result 
var_dump($data); 
curl_close($ch); 
} 
echo $json_post_fields; 

任何人都可以告訴我如何解決是問題。

Answer 1

您應該檢查您發送的請求，並將正文中的JSON與有效的請求進行比較，以真正瞭解發生了什麼。 json_encode的輸出將是一個數組，但API需要一個對象。你的請求主體必須

[{"email":"hello@test.com","first_name":"hh","last_name":"User"}] 

什麼你現在正在做正確的派遣

{"email":"hello@test.com","first_name":"hh","last_name":"User"} 

可以解決這個問題的幾種方法。你可以使用你最喜歡的字符串操作函數來附加括號，或者你可以跳過編碼並將JSON作爲字符串發送（因爲你指定了內容類型）。

在查看sendgrid API並在我自己的服務器上測試後，我能夠將聯繫人添加到聯繫人列表中。由於您已經創建了列表，下一步是創建要添加到列表中的收件人。你可以這樣做

<?php 

$url = 'https://api.sendgrid.com/v3/'; 
$request = $url.'contactdb/recipients'; //12345 is list_id 
$params = array(array(
'email' => 'amitkray@gmail.com', 
'first_name' => 'Amit', 
'last_name' => 'Kumar' 
)); 
$json_post_fields = json_encode($params); 
// Generate curl request 
$ch = curl_init(); 
$headers = 
array("Content-Type: application/json", 
"Authorization: Bearer SG.000000"); 
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_URL, $request); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_TIMEOUT, 60); 
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); 
// Apply the JSON to our curl call 
curl_setopt($ch, CURLOPT_POSTFIELDS, $json_post_fields); 
$data = curl_exec($ch); 
if (curl_errno($ch)) { 
print "Error: " . curl_error($ch); 
} else { 
// Show me the result 
curl_close($ch); 
} 
var_dump($data); 
?> 

創建收件人後，你現在可以將它們添加到列表中。你會得到一個像這樣的id YW1pdGtyYXlAZ21haWwuY29t這是你的電子郵件ID的base64編碼。

<?php 

$url = 'https://api.sendgrid.com/v3/'; 
$request = $url.'contactdb/lists/12345/recipients/YW1pdGtyYXlAZ21haWwuY29t'; //12345 is list_id 

// Generate curl request 
$ch = curl_init(); 
$headers = 
array("Content-Type: application/json", 
"Authorization: Bearer SG.00000000"); 
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_URL, $request); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_TIMEOUT, 60); 
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); 
// Apply the JSON to our curl call 
$data = curl_exec($ch); 
if (curl_errno($ch)) { 
print "Error: " . curl_error($ch); 
} else { 
// Show me the result 
curl_close($ch); 
} 
var_dump($data); 
?> 

補充說，你可以驗證，如果用戶已添加到列表

<?php 

$url = 'https://api.sendgrid.com/v3/'; 
$request = $url.'contactdb/lists/12345/recipients?page_size=100&page=1'; //12345 is list_id 

// Generate curl request 
$ch = curl_init(); 
$headers = 
array("Content-Type: application/json", 
"Authorization: Bearer SG.000000"); 
curl_setopt($ch, CURLOPT_GET, true); 
curl_setopt($ch, CURLOPT_URL, $request); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_TIMEOUT, 60); 
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); 
// Apply the JSON to our curl call 
$data = curl_exec($ch); 
if (curl_errno($ch)) { 
print "Error: " . curl_error($ch); 
} else { 
// Show me the result 

curl_close($ch); 
} 
var_dump($data); 
?> 

後注：最好的辦法就是因爲大部分代碼被重複創建一個類。我將爲sendgrid做一個包裝類，然後在這裏發佈它，並且能夠通過sendgrid API執行所有可能的任務。

第一個想到的是你需要插入您的電子郵件發送網收件人：

<?php 

    $curl = curl_init(); 

     $email = "example@mail.com"; 

    curl_setopt_array($curl, array(

     CURLOPT_URL => "https://api.sendgrid.com/v3/contactdb/recipients", 

     CURLOPT_RETURNTRANSFER => true, 
     CURLOPT_ENCODING => "", 
     CURLOPT_MAXREDIRS => 10, 
     CURLOPT_SSL_VERIFYPEER => false, 
     CURLOPT_TIMEOUT => 30, 
     CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1, 
     CURLOPT_CUSTOMREQUEST => "POST", 
     CURLOPT_POSTFIELDS => "[{\"email\": \".$email.\"}]", 
     CURLOPT_HTTPHEADER => array(
     "authorization: Bearer SG.0000000", 
     "content-type: application/json" 
    ), 
    )); 

    $response = curl_exec($curl); 
    $err = curl_error($curl); 

    curl_close($curl); 

    if ($err) { 
     echo "cURL Error #:" . $err; 
    } else { 
     echo $response; 
     $a = json_decode($response); 
     $b = $a->persisted_recipients; //get id of email 
     $r_id = $b[0];    // store it 

    } 

    ?> 

後，通過這樣的方式在列表中插入它。

$curl = curl_init(); 


curl_setopt_array($curl, array(

    CURLOPT_URL => "https://api.sendgrid.com/v3/contactdb/lists/123456/recipients/$r_id", 

    CURLOPT_RETURNTRANSFER => true, 
    CURLOPT_ENCODING => "", 
    CURLOPT_MAXREDIRS => 10, 
    CURLOPT_SSL_VERIFYPEER => false, 
    CURLOPT_TIMEOUT => 30, 
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1, 
    CURLOPT_CUSTOMREQUEST => "POST", 
    CURLOPT_POSTFIELDS => "null", 
    CURLOPT_HTTPHEADER => array(
    "authorization: Bearer SG.0000000000", 
    "content-type: application/json" 
), 
)); 

$response = curl_exec($curl); 
$err = curl_error($curl); 

curl_close($curl); 

if ($err) { 
    echo "cURL Error #:" . $err; 
} else { 
    echo $response; 
}
