流程

  • Client sends service discovery request to server
<iq from='admin@your@server'
    id='step_01'
    to='your@server'
    type='get'>
  <query xmlns='http://jabber.org/protocol/disco#items'/>
</iq>

Response: Server replies to service discovery request

  <iq xmlns="jabber:client" xml:lang="zh" xmlns:xml="http://www.w3.org/XML/1998/namespace" to="admin@your@server/eyeCU" type="result" from="your@server" id="step_01">

      <item xmlns="http://jabber.org/protocol/disco#items" name="已经停止的节点" jid="your@server" node="stopped nodes"/>
    </query>
  </iq>
  • Client sends service discovery request to upload service
<iq from='admin@your@server'
    id='step_02'
    to='upload.your@server'
    type='get'>
  <query xmlns='http://jabber.org/protocol/disco#info'/>
</iq>

Response:

  <iq xmlns="jabber:client" xml:lang="zh" xmlns:xml="http://www.w3.org/XML/1998/namespace" to="admin@your@server/eyeCU" type="result" from="upload.your@server" id="step_02">

        </field>
      </x>
    </query>
  </iq>
  • Client requests a slot on the upload service
<iq from='admin@your@server'
    id='step_03'
    to='upload.your@server'
    type='get'>
  <request xmlns='urn:xmpp:http:upload:0'
    filename='1.jpg'
    size='191453'
    content-type='image/jpeg' />
</iq>

这步申请槽，可以得到最终的put地址和get地址

Reponse:

    <iq xmlns="jabber:client" xml:lang="zh" xmlns:xml="http://www.w3.org/XML/1998/namespace" to="admin@your@server/eyeCU" type="result" from="upload.your@server" id="step_03">
    <slot xmlns="urn:xmpp:http:upload:0">
      <get xmlns="urn:xmpp:http:upload:0" url="http://your@server:5280/upload/18835e3044c959a859c7fd62cda467e563ba216a/tLJ0KIbEq64xYkk1paEo9F7xAkTmaugbXoHxMQNA/1.jpg"/>
      <put xmlns="urn:xmpp:http:upload:0" url="http://your@server:5280/upload/18835e3044c959a859c7fd62cda467e563ba216a/tLJ0KIbEq64xYkk1paEo9F7xAkTmaugbXoHxMQNA/1.jpg"/>
    </slot>
  </iq>

然后用post-man put到地址:

注意server 的 docroot目录(/opt/ejabberd/static)是ejabberd user权限:

ejabberd ejabberd 4.0K Nov  7 15:21 static

上传后看到文件来了:

/opt/ejabberd/static/18835e3044c959a859c7fd62cda467e563ba216a/tLJ0KIbEq64xYkk1paEo9F7xAkTmaugbXoHxMQNA

把file_server架设在外部
