由于我们的后台和前台是不同的php框架，而且后台和前台不在同一台服务器上，现在有一个问题，就是从后台上传图片要保存在前台的框架中。

我们后台用的是laravel框架

public function laraveltest(Request $request) {

$file = $request->file('file');

if($file -> isValid()){

$clientName = $file -> getClientOriginalName();

$tmpName = $file ->getFileName();

$realPath = $file -> getRealPath();

$entension = $file -> getClientOriginalExtension();

$newName = md5($clientName).".".$entension;

$url_path = 'upload/banner/';

$path = $file -> move($url_path,$newName);

$pathName = json_decode($path,TRUE);

$url1 = "http://47.101.54.26/test/testuploadpic";

$url2 = "http://47.101.54.27/test/testuploadpic";

$url3 = "http://47.101.54.28/test/testuploadpic";

$this->curl($path,$url1);

$this->curl($path,$url2);

$this->curl($path,$url3);

$returnPath = '/upload/banner/'.$newName;

return $this->json($returnPath);

}

}

public function curl($path,$url){

$curl = curl_init();

if (class_exists('\CURLFile')) {

curl_setopt($curl, CURLOPT_SAFE_UPLOAD, true);

$data = array('file' => new \CURLFile(realpath($path)));//>=5.5

}else{

if (defined('CURLOPT_SAFE_UPLOAD')) {

curl_setopt($curl, CURLOPT_SAFE_UPLOAD, false);

}

$data = array('file' => '@' . realpath($path));//<=5.5

}

curl_setopt($curl, CURLOPT_URL, $url);

curl_setopt($curl, CURLOPT_POST, 1 );

curl_setopt($curl, CURLOPT_POSTFIELDS, $data);

curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($curl, CURLOPT_USERAGENT,"TEST");

$result = curl_exec($curl);

$error = curl_error($curl);

}

通过上面两个方法就可以将图片发送到另外一台服务器，我写了3台服务器是因为我想说明可以发送到无数台服务器

下面的代码是在另外一台服务器上接收到图片信息后保存图片

public function testuploadpic(){

$filename = $_FILES['file']['name'];

$tmpname = $_FILES['file']['tmp_name'];

$url = '/home/testuploadpic';

if(move_uploaded_file($tmpname, $url.$filename))

{

echo json_encode('上传成功');

}

}

这样就可以保存下来了！！！
