如何通过卷曲帖子将文件上传到 api

Question

这是$_POST

Array
(
[name] => image.png
[type] => image/png 
[tmp_name] => C:xampp5tmpphpA637.tmp
[error] => 0
[size] => 16412
)

这是代码：

$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_PORT => "2403",
CURLOPT_URL => "http://".cfg('api_ip').":2403/sk_group/update_profile_pic", //url
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => "------WebKitFormBoundary7MA4YWxkTrZu0gWrnContent-Disposition: form-data; name="data"rnrn{"groupId":"".$group."","profile_pic":"".$name.""}rn------WebKitFormBoundary7MA4YWxkTrZu0gWrnContent-Disposition: form-data; name="profile_pic"; filename="".$file.""rnContent-Type: ".$type."rnrnrn------WebKitFormBoundary7MA4YWxkTrZu0gW--",
CURLOPT_HTTPHEADER => array(            
"SessionId: ".$_SESSION['session']."",
"VersionCode: ".cfg('version_code')."",
"content-type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW"
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
redirect("/meme/me/group"."?msg=".urldecode('Update icon group succes')."&type_msg=success");
}

我想知道如何$file图像以成功上传，因为 $_POST 只显示文件名而不是完整路径。

这是我拥有的控制器中的全部功能

function one()
{   
$filename = $_FILES['icon']['name'];    
$filedata = $_FILES['icon']['tmp_name'];
$filetype = $_FILES['icon']['type'];
two($_POST['group'], $filename, $filedata, $filetype);
}

我的助手上的此功能

function two($group, $name, $file, $type)
{   
$cFile = new CURLFile($file,$type,$name);
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_PORT => "2403",
CURLOPT_URL => "http://".cfg('api_ip').":2403/sk_group/update_profile_pic",
CURLOPT_HEADER => true,
CURLOPT_SSL_VERIFYPEER => false,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_POST => true,
CURLOPT_FOLLOWLOCATION => true,     
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => "------WebKitFormBoundary7MA4YWxkTrZu0gWrnContent-Disposition: form-data; name="data"rnrn{"groupId":"".$group."","profile_pic":"".$name.""}rn------WebKitFormBoundary7MA4YWxkTrZu0gWrnContent-Disposition: form-data; name="profile_pic"; filename="".$cFile.""rnContent-Type: ".$type."rnrnrn------WebKitFormBoundary7MA4YWxkTrZu0gW--",
CURLOPT_HTTPHEADER => array(            
"SessionId: ".$_SESSION['session']."",
"VersionCode: ".cfg('version_code')."",
"content-type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW"
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
redirect("/meme/me/group"."?msg=".urldecode('Update icon group succes')."&type_msg=success");
}
}

仍然有同样的问题，就像我问...，文件在哪里？ 以及如何发布它直到成功？

我在这里发布了相同的答案

从 PHP 5.5 及以上版本开始，CURL 将使用 CURL 文件上传文件，对于较低的 PHP 版本，您需要手动生成表单边界，然后发送文件。下面的代码示例处理这两种情况。

为方便起见，这是主要部分：

<?php
$file = "websites.txt";
upload_with_compatibility($file);
function upload_with_compatibility($file){
if (version_compare(phpversion(), '5.5', '>=')) {
echo "Upload will be done using CURLFilen";
upload($file); //CURL file upload using CURLFile for PHP v5.5 or greater
}else{
echo "Upload will be done without CURLFilen";
compatibleUpload($file); //CURL file upload without CURLFile for PHP less than v5.5
}
}
//Upload file using CURLFile
function upload($file){
$target = "http://localhost:8888/upload_file.php";
$host = parse_url($target);
$cFile = new CURLFile($file,'text/plain', $file);
$data = array(
'log_file' => $cFile,
);
//you can play around with headers, and adjust as per your need
$agent = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.101 Safari/537.36';
$curlHeaders = array(
'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8',
