How to send parameters in curl in php - php

Question

How would I write below command in curl php:
curl -XPOST https://apiv2.unificationengine.com/v2/message/send
–data
“{ \"message\”: { \“receivers\”: [{\“name\”: \“TO_NAME \”,
\“address\”: \“TO_EMAILADDRESS\” ,
\“Connector\”: \“UNIQUE_CONNECTION_IDENTIFIER\”,
\“type\”: \“to\”}],\“sender\”: {\“address\”: \“EMAIL_ADDRESS\”},
\“subject\”:\“Hello\”,\“parts\”: [{\“id\”: \“1\”,
\“contentType\”: \“text/plain\”,
\“data\”:\“Hi welcome to UE\” ,
\“size\”: 100,\“type\”: \“body\”,\“sort\”:0}]}}“
-u USER_ACCESSKEY:USER_ACCESSSECRET -k
if this is the right way to execute and write curl in php:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"http://abcproject.com/tester.phtml");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
"postvar1=value1&postvar2=value2&postvar3=value3");
// in real life you should use something like:
// curl_setopt($ch, CURLOPT_POSTFIELDS,
// http_build_query(array('postvar1' => 'value1')));
// receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$server_output = curl_exec ($ch);
curl_close ($ch);
// further processing ....
if ($server_output == "OK") { ... } else { ... }
Here is more sample code SO question.
But I am finding problem that where to mentions -u, --data options in php curl.

Answer 1

curl -u is equivalent to CURLOPT_USERPWD in php-curl.
You set it with curl_setopt, as the others.
--data is CURLOPT_POSTFIELDS, which you are already sending. But in your case you'd want to populate with the json you want to send.
If you are sending a JSON, you'd do well in setting the Content-type header (and content-length wouldn't be amiss either)
Be careful, in your example call there are some weird characters. But the JSON you posted is equivalent to:
$yourjson = <<<EOF
{
"message": {
"receivers": [
{
"name": "TO_NAME ",
"address": "TO_EMAILADDRESS",
"Connector": "UNIQUE_CONNECTION_IDENTIFIER",
"type": "to"
}
],
"sender": {
"address": "EMAIL_ADDRESS"
},
"subject": "Hello",
"parts": [
{
"id": "1",
"contentType": "text/plain",
"data": "Hi welcome to UE",
"size": 100,
"type": "body",
"sort": 0
}
]
}
}
EOF;
But usually you'd start with your data in array form and json_encode it.
So you'd start with something like:
$array = [
'message' =>
[
'receivers' =>
[
0 =>
[
'name' => 'TO_NAME ',
'address' => 'TO_EMAILADDRESS',
'Connector' => 'UNIQUE_CONNECTION_IDENTIFIER',
'type' => 'to',
],
],
'sender' =>
[
'address' => 'EMAIL_ADDRESS',
],
'subject' => 'Hello',
'parts' =>
[
0 =>
[
'id' => '1',
'contentType' => 'text/plain',
'data' => 'Hi welcome to UE',
'size' => 100,
'type' => 'body',
'sort' => 0,
],
],
],
];
... convert that using $yourjson = json_encode($array), and that's it.
E.g.:
// you already have your json inside of $yourjson,
// plus your username and password in their respective variables.
curl_setopt($ch, CURLOPT_USERPWD, "$user:$pass");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_POSTFIELDS, $yourjson);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, [
'Content-Type: application/json',
'Content-Length: ' . strlen($yourjson)
]
);

Answer 2

to send data as JSON add header content-type and set as JSON and add the option CURLOPT_USERPWD, something like this:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"https://apiv2.unificationengine.com/v2/message/send");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
curl_setopt($ch, CURLOPT_POSTFIELDS,
“{ \"message\”: { \“receivers\”: [{\“name\”: \“TO_NAME \”, \“address\”: \“TO_EMAILADDRESS\” , \“Connector\”: \“UNIQUE_CONNECTION_IDENTIFIER\”, \“type\”: \“to\”}],\“sender\”: {\“address\”: \“EMAIL_ADDRESS\”},\“subject\”:\“Hello\”,\“parts\”: [{\“id\”: \“1\”,\“contentType\”: \“text/plain\”, \“data\”:\“Hi welcome to UE\” ,\“size\”: 100,\“type\”: \“body\”,\“sort\”:0}]}}“);
// in real life you should use something like:
// curl_setopt($ch, CURLOPT_POSTFIELDS,
// http_build_query(array('postvar1' => 'value1')));
// receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
$server_output = curl_exec ($ch);
curl_close ($ch);
