带有JSON主体的POST请求

您需要使用cURL库来发送此请求。

<?php
// Your ID and token
$blogID = '8070105920543249955';
$authToken = 'OAuth 2.0 token here';
// The data to send to the API
$postData = array(
    'kind' => 'blogger#post',
    'blog' => array('id' => $blogID),
    'title' => 'A new post',
    'content' => 'With <b>exciting</b> content...'
);
// Setup cURL
$ch = curl_init('https://www.googleapis.com/blogger/v3/blogs/'.$blogID.'/posts/');
curl_setopt_array($ch, array(
    CURLOPT_POST => TRUE,
    CURLOPT_RETURNTRANSFER => TRUE,
    CURLOPT_HTTPHEADER => array(
        'Authorization: '.$authToken,
        'Content-Type: application/json'
    ),
    CURLOPT_POSTFIELDS => json_encode($postData)
));
// Send the request
$response = curl_exec($ch);
// Check for errors
if($response === FALSE){
    die(curl_error($ch));
}
// Decode the response
$responseData = json_decode($response, TRUE);
// Close the cURL handler
curl_close($ch);
// Print the date from the response
echo $responseData['published'];

如果，出于某种原因，你不能或不想使用cURL，你可以这样做:

<?php
// Your ID and token
$blogID = '8070105920543249955';
$authToken = 'OAuth 2.0 token here';
// The data to send to the API
$postData = array(
    'kind' => 'blogger#post',
    'blog' => array('id' => $blogID),
    'title' => 'A new post',
    'content' => 'With <b>exciting</b> content...'
);
// Create the context for the request
$context = stream_context_create(array(
    'http' => array(
        // http://www.php.net/manual/en/context.http.php
        'method' => 'POST',
        'header' => "Authorization: {$authToken}'r'n".
            "Content-Type: application/json'r'n",
        'content' => json_encode($postData)
    )
));
// Send the request
$response = file_get_contents('https://www.googleapis.com/blogger/v3/blogs/'.$blogID.'/posts/', FALSE, $context);
// Check for errors
if($response === FALSE){
    die('Error');
}
// Decode the response
$responseData = json_decode($response, TRUE);
// Print the date from the response
echo $responseData['published'];

我认为cURL是一个很好的解决方案。这没有经过测试，但您可以尝试这样做:

$body = '{
  "kind": "blogger#post",
  "blog": {
    "id": "8070105920543249955"
  },
  "title": "A new post",
  "content": "With <b>exciting</b> content..."
}';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.googleapis.com/blogger/v3/blogs/8070105920543249955/posts/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json","Authorization: OAuth 2.0 token here"));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $body);
$result = curl_exec($ch);

如果你不想使用CURL，你可以在stackoverflow上找到一些例子，就像这里的这个:我如何用PHP发送POST请求?我建议你看一些关于如何在PHP中使用GET和POST方法的教程，或者看看这里的php.net手册:httprequest::send。你可以找到很多教程:从PHP HTTP POST，没有cURL等等…

我基于@Rocket Hazmat， @dbau和@maraca代码，通过网站上的表单向prosperworks发送数据。我希望，它会帮助别人:

<?php
if(isset($_POST['submit'])) {
    //form's fields name:
    $name = $_POST['nameField'];
    $email = $_POST['emailField'];
    //API url:
    $url = 'https://api.prosperworks.com/developer_api/v1/leads';
    //JSON data(not exact, but will be compiled to JSON) file:
    //add as many data as you need (according to prosperworks doc):
    $data = array(
                            'name' => $name,
                            'email' => array('email' => $email)
                        );
    //sending request (according to prosperworks documentation):
    // use key 'http' even if you send the request to https://...
    $options = array(
        'http' => array(
            'header'  => "Content-Type: application/json'r'n".
             "X-PW-AccessToken: YOUR_TOKEN_HERE'r'n".
             "X-PW-Application:developer_api'r'n".
             "X-PW-UserEmail: YOUR_EMAIL_HERE'r'n",
            'method'  => 'POST',
            'content' => json_encode($data)
        )
    );
    //engine:
    $context  = stream_context_create($options);
    $result = file_get_contents($url, false, $context);
    if ($result === FALSE) { /* Handle error */ }
    //compiling to JSON (as wrote above):
    $resultData = json_decode($result, TRUE);
    //display what was sent:
    echo '<h2>Sent: </h2>';
    echo $resultData['published'];
    //dump var:
    var_dump($result);
}
?>
<html>
    <head>
    </head>
    <body>
        <form action="" method="POST">
