PHP使用CURL上传文件到远程服务接口
当然你的php.ini开启了curl扩展功能
1、文件上传
/**
* 以文件上传 第二种方法
*/
public function upload(){
$result = array('code' => 0, 'message' => 'ok');
ini_set('upload_max_filesize', '20M');
ini_set('post_max_size', '20M');
ini_set('memory_limit', '128M');
$url="http://xx.xx.xx.xx/api/file/upload"; //远程接口地址
$file = $_FILES['file'];
if ($file['error'] != 0) {
$result['code'] = 40001;
$result['message'] = '上传出错';
$this->error(); //使用Thinkphp5.1内置controller方法
} else {
$filename = $file['name'];
$tmpfile = $file['tmp_name'];
$filetype = $file['type'];
$data = self::upload_file($url, $filename, $tmpfile, $filetype);
$data = json_decode($data,true);
$this->success(); ////使用Thinkphp5.1内置controller方法
die;
}
}
/**
* curl上传文件
*
* @param unknown $url
* @param unknown $filename
* @param unknown $path
* @param unknown $type
*/
protected function upload_file($url,$filename,$path,$type){
//php 5.5以上的用法
if (class_exists('\CURLFile')) {
$data = array('file' => new \CURLFile(realpath($path),$type,$filename));
} else {
$data = array(
'file'=>'@'.realpath($path).";type=".$type.";filename=".$filename
);
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true );
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$return_data = curl_exec($ch);
curl_close($ch);
echo $return_data;
}
2、文件接收端（不限定于PHP)
/**
* 接收文件
*/
public function upload(){
Log::info('--------------$_FILES--------------------');
Log::info($_FILES);
if( $_FILES){
$filename = $_FILES['file']['name'];
$tmpname = $_FILES['file']['tmp_name'];
if(move_uploaded_file($tmpname, $_SERVER['DOCUMENT_ROOT']."/excel-file/" .$filename)){
echo json_encode('上传成功');
}else{
$data = json_encode($_FILES);
echo $data;
}
}
}
3、以下是以二进制文件上传偶尔会失败，故而不推荐使用，在此记录下！
/**
* 以二进制文件上传
*/
public function upload_stream(){
$url="http://xx.xx.xx.xx/api/file/upload"; //上传远程接口地址
$info = $_FILES['file'];
$fp = fopen($info['tmp_name'], 'r');
$filebinary = fread($fp, filesize($info['tmp_name']));
fclose($fp);
$opts = array(
'http' => array(
'method' => 'POST',
'header' => 'content-type:application/x-www-form-urlencoded',
'context' => $filebinary
)
);
$context = stream_context_create($opts);
$response = file_get_contents($url, false, $context); //就是这个方法 偶尔会失败哦！
$ret = json_decode($response, true);
return $ret['success'];
}
//以下服务部署于服务端(不限定于PHP)
/**
* 接收二进制流文件
*/
public function upload_stream(){
$streamData = isset($GLOBALS['HTTP_RAW_POST_DATA']) ? $GLOBALS['HTTP_RAW_POST_DATA'] : '';
$receiveFile = $_SERVER['DOCUMENT_ROOT']."/excel-file/receiv.xlsx";
if(empty($streamData)){
$streamData = file_get_contents('php://input');
}
if($streamData!=''){
$ret = file_put_contents($receiveFile, $streamData, true);
}else{
$ret = false;
}
return $ret;
}
