使用cURL使用内容类型发送数据和文件:application/json

下面将使用cURL发送数据以及使用 content-type application/x-www-form-urlencoded

我不想用 Content-Type: application/x-www-form-urlencoded 但是用 Content-Type: application/json .

内容类型:application/json .

内容类型:application/json ?

以下代码x-www-form-urlencoded仅供参考

<?php
//Given:
$method='post';
$url='http://php.net/manual/en/function.curl-setopt.php';
$data=['hello'=>123];
$files=["image"=>["name" => "picture.jpg","type" => "image/jpeg","tmp_name" => "/path/on/server/to/tmp/phprj5rkG","error" => 0,"size" => 174476]];

//For using content-type application/x-www-form-urlencoded

$postData = [];
if($files) {
    //cURL doesn't work out of the box with both files and POST data.
    foreach ($files as $name=>$file){
        $postData[$name] = new \CURLFile($file['tmp_name'],$file['type'],$file['name']);
    }
    if($data) {
        foreach (explode('&', http_build_query($data)) as $pair){
            list($name, $value) = explode('=', $pair, 2);
            $postData[urldecode($name)] = urldecode($value);
        }
    }
}
else {
    $postData=http_build_query($data);
}

$options=[
    CURLOPT_RETURNTRANSFER => true,     // return web page
    CURLOPT_HEADER         => false,    // don't return headers
    CURLOPT_FOLLOWLOCATION => true,     // follow redirects
    CURLOPT_ENCODING       => "",       // handle all encodings
    CURLOPT_AUTOREFERER    => true,     // set referrer on redirect
];
switch ($method) {
    case "get":
        if ($postData) {$url = sprintf("%s?%s", $url, $postData);}
        break;
    case "post":
        $options[CURLOPT_POST]=1;
        $options[CURLOPT_POSTFIELDS]=$postData?$postData:'';
        break;
    case "put":
        $options[CURLOPT_CUSTOMREQUEST]="PUT";
        if ($postData) {$options[CURLOPT_POSTFIELDS]=$postData;}
        break;
    case "delete":
        $options[CURLOPT_CUSTOMREQUEST]="DELETE";
        if ($postData) {$options[CURLOPT_POSTFIELDS]=$postData;}
        break;
}
$options[CURLOPT_URL]=$url;
$ch      = curl_init();
curl_setopt_array( $ch, $options );

$rsp=curl_exec( $ch );
