[英]Generating JSON via multi-dimensional array
我需要通過在 PHP 中將它們拉到一起來重新創建它:
{
"content": [
{
"type": "text/plain",
"value": " "
}
],
"from": {
"email": "dx@sendgrid.com",
"name": "Ryan Smith"
},
"personalizations": [
{
"to": [
{
"email": "elmer@sendgrid.com"
}
]
}
],
"subject": "my subject"
}
這就是我所擁有的,但它並不完全正確:
$content ='some long string';
$to =array('email'=>'elmer@sendgrid.com');
$objectArray = array(
'content'=> array ('type'=>'text/html', 'value'=>$content),
'from'=>array('from'=>'dx@sendgrid.com','name'=>'Ryan Smith'),
'subject'=>'my subject',
'personalizations'=> array('to'=>$to)
);
$postfields = json_encode($objectArray);
編輯
抱歉點擊得太早了。
這是返回的錯誤:
{
"errors": [
{
"message": "Invalid type. Expected: array, given: object.",
"field": "content",
"help": "http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#message.content"
},
{
"message": "Invalid type. Expected: array, given: object.",
"field": "personalizations",
"help": "http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#-Personalizations-Errors"
}
]
}
我在這里做錯了什么?
content
屬性是一個 arrays 數組,因為您可能需要發送多個內容類型(即text/plain
和text/html
)。 personalizations
也是如此。
'content' => [
[
'type' => 'text/plain',
'value' => $textContent
],
// ...
],
'personalizations' = [
[
'to' => [
[
'email' => $email,
'name' => $name
]
],
'subject' => $subject
],
// ...
];
