我有一个带有文件上传字段的表单，该字段将它发布到我的端点。从那里，我想将文件发布到我使用的 API。
实现这一目标的最佳方法是什么？
我是否必须从临时存储中移动文件才能将其发布到 API？或者也许我必须添加 cURL 选项？
.HTML：
<form method="post" action="/my_endpoint">
<div class="form-group">
<label for="resume">Resume*</label>
<input type="file" class="form-control" id="resume" name="resume" placeholder="Resume" required />
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
.PHP：
$f3->route('POST /my_endpoint',
function($f3) {
$url = API_ENDPOINT;
$post_params = $f3->get('POST');
$files_params = $f3->get('FILES');
$fields = array(
'id' => $post_params['id'],
'email' => $post_params['email'],
'resume' => '@'.$files_params['resume']['tmp_name']
);
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string, '&');
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_HTTPHEADER, array("Content-Type:multipart/form-data"));
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
$result = curl_exec($ch);
curl_close($ch);
}
);
我采纳了@Barmar的建议，创建了一个卷曲文件。
$f3->route('POST /my_endpoint',
function($f3) {
$url = API_ENDPOINT;
$post_params = $f3->get('POST');
$files_params = $f3->get('FILES');
$resume_file = curl_file_create(realpath($files_params['resume']['tmp_name']),$files_params['resume']['type'],$files_params['resume']['name']);
$fields = array(
'id' => $post_params['id'],
'email' => $post_params['email'],
'resume' => $resume_file
);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_HTTPHEADER, array("Content-Type:multipart/form-data"));
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields);
$result = curl_exec($ch);
curl_close($ch);
}
);
然后它奏效了。
