curl上传图片，服务器端接受不到图片

本地测试：
图片的位置：就是在curl的目录下，
E:\Apache24\htdocs\curl\img_8176.jpg
本地环境：
Window x64位
Apache2.4
PHP7.0 ：也就是正式版的第一版
无mysql
代码如下：

curl_upload.php

	10086,	'pic'	=>	"@".realpath('./img_8176.jpg').";type=image/png");print_r($data);$ch = curl_init();curl_setopt($ch, CURLOPT_URL, 'http://192.168.10.103/curl/upload_server.php' );curl_setopt($ch, CURLOPT_POST, true );//curl_setopt ( $ch, CURLOPT_SSL_VERIFYPEER, FALSE);//curl_setopt($ch,CURLOPT_USERAGENT,$_SERVER['HTTP_USER_AGENT']);//模拟浏览器动作curl_setopt ( $ch, CURLOPT_SSL_VERIFYHOST, false );curl_setopt($ch, CURLOPT_POSTFIELDS, $data);curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));//curl_setopt($ch, CURLOPT_HEADER, false);curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);$return_data= curl_exec($ch);echo "
";print_r($return_data);echo "
";curl_close($ch);var_dump($return_data); if(@curl_errno($return_data)==0){        return json_decode($return_data,true);    }else {        return false;    }?>

对于服务器端：
upload_server.php

运行的结果：





Array ( [uid] => 10086 [pic] => @E:\Apache24\htdocs\curl\img_8176.jpg;type=image/png )

Array
(
[uid] => 10086
[pic] => @E:\Apache24\htdocs\curl\img_8176.jpg;type=image/png
)
