如何使用 DLNA 浏览 Synology NAS 上的目录？

Question

GET http://192.168.1.5:50001/desc/device.xml

返回以下数据：

<?xml version="1.0" encoding="utf-8"?>
<root xmlns="urn:schemas-upnp-org:device-1-0">
    <specVersion>
        <major>1</major>

        </iconList>

            <service>
                <serviceType>urn:schemas-upnp-org:service:ConnectionManager:1</serviceType>

                <controlURL>/ConnectionManager/control</controlURL>
                <eventSubURL>/ConnectionManager/event</eventSubURL>
            </service>
            <service>
                <serviceType>urn:schemas-upnp-org:service:ContentDirectory:1</serviceType>
                <serviceId>urn:upnp-org:serviceId:ContentDirectory</serviceId>
                <SCPDURL>/cdsSCPD.xml</SCPDURL>
                <controlURL>/ContentDirectory/control</controlURL>
                <eventSubURL>/ContentDirectory/event</eventSubURL>
            </service>
            <service>
                <serviceType>urn:microsoft.com:service:X_MS_MediaReceiverRegistrar:1</serviceType>
                <serviceId>urn:microsoft.com:serviceId:X_MS_MediaReceiverRegistrar</serviceId>

            </service>
        </serviceList>
    </device>
</root>

当我尝试执行以下请求时：

curl --location 'http://192.168.1.5:50001/ContentDirectory/control' \
--header 'SOAPAction: urn:schemas-upnp-org:service:ContentDirectory:1#Browse' \
--header 'Content-Type: text/xml; charset="utf-8"' \
--data '<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
    <s:Body>
        <u:Browse xmlns:u="urn:schemas-upnp-org:service:ContentDirectory:1">
            <ObjectID>0</ObjectID>
            <BrowseFlag>BrowseDirectChildren</BrowseFlag>
            <Filter>*</Filter>
            <StartingIndex>0</StartingIndex>
            <RequestedCount>1000</RequestedCount>
            <SortCriteria></SortCriteria>
        </u:Browse>
    </s:Body>
</s:Envelope>

我收到错误代码

-111: Invalid Action

。这里有什么问题吗？ 我尝试从操作中删除

#Browse

并仅发送

#Browse

- 这没有帮助。

根据服务器回复，Synology 使用

Linux/2.6.32.12, UPnP/1.0, Portable SDK for UPnP devices/1.6.18

。

Answer 1

根据 UPnP 设备架构规范第 3.2 节，调用操作的标头如下所示

POST path of control URL HTTP/1.1
HOST: host of control URL:port of control URL
CONTENT-LENGTH: bytes in body
CONTENT-TYPE: text/xml; charset="utf-8"
SOAPACTION: "urn:schemas-upnp-org:service:serviceType:v#actionName"

所需的 HTTP 方法是

POST

；你的命令没有设置这个。

我对curl不太熟悉，但认为添加

-X POST

可能会达到你想要的效果。
