关于在Linux服务器下PHP调用python的问题与解决方案路线

目的：客户端上传图片，服务器接收并交至python处理。

1.一个简单的解决方案思维导图

2.PHP的socket客户端源码

<?php
 $mypath = $_POST['path'];
 set_time_limit(0);
 $host="172.18.66.250";
 print_r("path:".$mypath.";");
 $port=8888;
 $flag = 0x2;
 $socket=socket_create(AF_INET,SOCK_STREAM,SOL_TCP)or die("cannot create socket\n");
 $conn=socket_connect($socket,$host,$port) or die("cannot connect server\n");
 if($conn){echo "client connect ok!";}
 socket_write($socket,$mypath."+/opt/lampp/htdocs/imgWebserver/output") or die("cannot write data\n");
 $buffer=socket_read($socket,1024);
 echo "response was+".$buffer."response was+";
 socket_close($socket);
?>

3.PHP的图片上传源码

<?php
//获取ajax传来的base64编码，$_POST['img']是你后台获取到的图片
$base64_image_content = $_POST['img'];
$name = $_POST['name'];
//图片保存的位置
$path= './upload/';
//这个是自定义函数，将Base64图片转换为本地图片并保存
$data = base64_image_content($base64_image_content,$path,$name);
#echo $data;
/**
 * 将Base64图片转换为本地图片并保存
 * @param  $base64_image_content 要保存的Base64
 * @param  $path 要保存的路径
 */
function base64_image_content($base64_image_content,$path,$name){
	//匹配出图片的格式
	if (preg_match('/^(data:\s*image\/(\w+);base64,)/', $base64_image_content, $result)){
		//后缀 
		$type = $result[2];
		//创建文件夹，以年月日
		$new_file = $path."/";
		if(!file_exists($new_file)){
			//检查是否有该文件夹，如果没有就创建，并给予最高权限
			mkdir($new_file, 0700);
		}
		$new_file = $new_file.$name.".{$type}";	//图片名以时间命名
		//保存为文件
		if (file_put_contents($new_file, base64_decode(str_replace($result[1], '', $base64_image_content)))){
			//返回这个图片的路径
		    return $new_file;
		}else{
			return false;
		}
	}else{
		return false;
	}
}

4.python服务端源码

	if path not in sys.path:
		sys.path.append(path)

this_dir=osp.dirname(__file__)
lib_path=osp.join(this_dir,'tools')
add_path(lib_path)
add_path(this_dir)

	(Area, averageDist,mask,mask1,t)=testSingleImg(image_list,output)
	return Area, averageDist, t	

if __name__ == "__main__":

    tcp_server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    # 绑定端口
    tcp_server_socket.bind(("172.18.66.250", 8888))
    # 设置监听，把服务端socket由主动套接字改成被动套接字，只能接收客户端的连接请求
    tcp_server_socket.listen(128)
    while True:
        try:
            print("开始监听.......")
            client_socket, client_ip = tcp_server_socket.accept()

            str_recive = client_socket.recv(1024)

                data_str=str(str_recive)
                print(data_str)
                str1 = data_str.split("+")
                str2 = str1[0]
                str3 = str1[1]
                print(str2)
                print(str3)
                
                Area,averageDist,t=runPredict(str2,str3)
                #print('The area =%f and average distance =%f'%(Area, averageDist))
                print Area, averageDist, t
                
                client_socket.send(str(averageDist).encode("utf-8"))
                str(averageDist).encode("utf-8").split("1")
            else:
                break
        except Exception,e:
            print e.message
            client_socket.close()
