zope.app.file webdav集成

>>> import z3c.etree
>>> from zope.app.file.file import File

>>> etree = z3c.etree.getEngine()

在根目录中创建一个名为textfile.txt的内容对象。

>>> f = File('%s\n' %('x' * 10) * 5, 'text/plain')
>>> getRootFolder()['testfile.txt'] = f

GET

为了使WebDAV客户端能够获取符合DAV资源的数据，需要设置内容对象的默认视图。

>>> resp = http("""
... GET /testfile.txt HTTP/1.1
... """, handle_errors = False)
>>> resp.getStatus()
200
>>> resp.getHeader('content-type')
'text/plain'
>>> resp.getHeader('content-length')
'55'
>>> print resp.getBody()
xxxxxxxxxx
xxxxxxxxxx
xxxxxxxxxx
xxxxxxxxxx
xxxxxxxxxx

PUT

???

PROPFIND

查询文件对象的WebDAV数据模型。以下属性目前构成了zope.file的数据模型

  • {DAV:}creationdate

  • {DAV:}displayname

  • {DAV:}getcontentlength

  • {DAV:}getcontenttype

  • {DAV:}getlastmodified

  • {DAV:}resourcetype

查询测试文件的全部属性。

>>> resp = webdav("""
... PROPFIND /testfile.txt HTTP/1.1
... """, handle_errors = False)

>>> print resp.getBody() #doctest:+XMLDATA
<multistatus xmlns="DAV:">
  <response>
    <href>http://localhost/testfile.txt</href>
    <propstat>
      <prop>
        <creationdate />
        <displayname />
        <getlastmodified />
        <getcontenttype>text/plain</getcontenttype>
        <getcontentlength>55</getcontentlength>
        <resourcetype />
      </prop>
      <status>HTTP/1.1 200 Ok</status>
    </propstat>
  </response>
</multistatus>

在文件对象上，{DAV:}getetag 和 {DAV:}getcontentlanguage 属性（尚未）定义。

>>> resp.getMSProperty('http://localhost/testfile.txt', '{DAV:}getetag')
Traceback (most recent call last):
...
KeyError: "'{DAV:}getetag' property not found for resource http://localhost/testfile.txt (200)"
>>> resp.getMSProperty(
...    'http://localhost/testfile.txt', '{DAV:}getcontentlanguage')
Traceback (most recent call last):
...
KeyError: "'{DAV:}getcontentlanguage' property not found for resource http://localhost/testfile.txt (200)"

PROPPATCH

我们需要登录才能更新属性。

>>> reqbody = """<propertyupdate xmlns="DAV:">
...  <set>
...   <prop>
...    <displayname>Test title</displayname>
...   </prop>
...  </set>
... </propertyupdate>"""
>>> resp = webdav("""
... PROPPATCH /testfile.txt HTTP/1.1
... Content-Type: application/xml
... Content-Length: %d
...
... %s""" %(len(reqbody), reqbody))
>>> resp.getStatus()
401

现在更新文件的标题。

>>> resp = webdav("""
... PROPPATCH /testfile.txt HTTP/1.1
... Authorization: Basic mgr:mgrpw
... Content-Type: application/xml
... Content-Length: %d
...
... %s""" %(len(reqbody), reqbody), handle_errors = False)
>>> resp.getStatus()
207
>>> resp.getHeader('content-type')
'application/xml'
>>> print resp.getBody() #doctest:+XMLDATA
<multistatus xmlns="DAV:">
  <response>
    <href>http://localhost/testfile.txt</href>
    <propstat>
      <prop>
        <displayname />
      </prop>
      <status>HTTP/1.1 200 Ok</status>
    </propstat>
  </response>
</multistatus>

使用PROPFIND检索displayname属性，并注意差异。

>>> reqbody = """<propfind xmlns="DAV:">
...   <prop>
...     <displayname />
...   </prop>
... </propfind>
... """
>>> resp = webdav("""
... PROPFIND /testfile.txt HTTP/1.1
... Content-type: application/xml
... Content-Length: %d
...
... %s""" %(len(reqbody), reqbody), handle_errors = False)
>>> resp.getStatus()
207
>>> resp.getHeader('content-type')
'application/xml'
>>> print resp.getBody() #doctest:+XMLDATA
<multistatus xmlns="DAV:">
  <response>
    <href>http://localhost/testfile.txt</href>
    <propstat>
      <prop>
        <displayname>Test title</displayname>
      </prop>
      <status>HTTP/1.1 200 Ok</status>
    </propstat>
  </response>
</multistatus>

{DAV:}getcontentlength 属性是一个实时属性，因此我们无法修改它。

>>> reqbody = """<propertyupdate xmlns="DAV:">
...   <set>
...     <prop>
...       <getcontentlength>24</getcontentlength>
...     </prop>
...   </set>
... </propertyupdate>"""
>>> resp = webdav("""
... PROPPATCH /testfile.txt HTTP/1.1
... Authorization: Basic mgr:mgrpw
... Content-type: application/xml
... Content-length: %d
...
... %s""" %(len(reqbody), reqbody))
>>> resp.getStatus()
207
>>> resp.getHeader('content-type')
'application/xml'
>>> print resp.getBody() #doctest:+XMLDATA
<multistatus xmlns="DAV:">
  <response>
    <href>http://localhost/testfile.txt</href>
    <propstat>
      <prop>
        <getcontentlength />
      </prop>
      <status>HTTP/1.1 403 Forbidden</status>
    </propstat>
  </response>
</multistatus>

不可见属性

在我们的资源上设置两个已死属性。

>>> reqbody = """<propertyupdate xmlns="DAV:">
...  <set>
...    <prop>
...      <E:prop1 xmlns:E="examplens:">PROPERTY 1</E:prop1>
...      <E:prop2 xmlns:E="examplens:">PROPERTY 2</E:prop2>
...    </prop>
...  </set>
... </propertyupdate>
... """
>>> resp = webdav("""
... PROPPATCH /testfile.txt HTTP/1.1
... Authorization: Basic mgr:mgrpw
... Content-type: application/xml
... Content-length: %d
...
... %s""" %(len(reqbody), reqbody), handle_errors = True)

>>> resp.getStatus()
207
>>> resp.getHeader('content-type')
'application/xml'
>>> print resp.getBody() #doctest:+XMLDATA
<multistatus xmlns="DAV:">
  <response>
    <href>http://localhost/testfile.txt</href>
    <propstat>
      <prop>
        <ns1:prop1 xmlns:ns1="examplens:" />
        <ns1:prop2 xmlns:ns1="examplens:" />
      </prop>
      <status>HTTP/1.1 200 Ok</status>
    </propstat>
  </response>
</multistatus>

查询这些新属性。

>>> reqbody = """<propfind xmlns="DAV:">
...  <prop xmlns:E="examplens:" >
...    <E:prop1 />
...    <E:prop2 />
...  </prop>
... </propfind>
... """
>>> resp = webdav("""
... PROPFIND /testfile.txt HTTP/1.1
... Content-type: application/xml
... Content-length: %d
...
... %s""" %(len(reqbody), reqbody))
>>> resp.getStatus()
207
>>> resp.getHeader('content-type')
'application/xml'
>>> print resp.getBody() #doctest:+XMLDATA
<multistatus xmlns="DAV:">
  <response>
    <href>http://localhost/testfile.txt</href>
    <propstat>
      <prop>
        <E:prop1 xmlns:E="examplens:">PROPERTY 1</E:prop1>
        <E:prop2 xmlns:E="examplens:">PROPERTY 2</E:prop2>
      </prop>
      <status>HTTP/1.1 200 Ok</status>
    </propstat>
  </response>
</multistatus>

更新第一个属性并删除第二个。

>>> reqbody = """<propertyupdate xmlns="DAV:">
...  <set>
...    <prop>
...      <E:prop1 xmlns:E="examplens:">Only opaque property</E:prop1>
...    </prop>
...  </set>
...  <remove>
...    <prop>
...      <E:prop2 xmlns:E="examplens:" />
...    </prop>
...  </remove>
... </propertyupdate>"""
>>> resp = webdav("""
... PROPPATCH /testfile.txt HTTP/1.1
... Authorization: Basic mgr:mgrpw
... Content-type: application/xml
... Content-length: %d
...
... %s""" %(len(reqbody), reqbody))
>>> resp.getStatus()
207
>>> resp.getHeader('content-type')
'application/xml'
>>> print resp.getBody() #doctest:+XMLDATA
<multistatus xmlns="DAV:">
  <response>
    <href>http://localhost/testfile.txt</href>
    <propstat>
      <prop>
        <E:prop1 xmlns:E="examplens:" />
        <E:prop2 xmlns:E="examplens:" />
      </prop>
      <status>HTTP/1.1 200 Ok</status>
    </propstat>
  </response>
</multistatus>

现在检查不可见属性是否已成功更新。

>>> reqbody = """<propfind xmlns="DAV:">
...  <prop xmlns:E="examplens:" >
...    <E:prop1 />
...    <E:prop2 />
...  </prop>
... </propfind>
... """
>>> resp = webdav("""
... PROPFIND /testfile.txt HTTP/1.1
... Content-type: application/xml
... Content-length: %d
...
... %s""" %(len(reqbody), reqbody))
>>> resp.getStatus()
207
>>> resp.getHeader('content-type')
'application/xml'
>>> print resp.getBody() #doctest:+XMLDATA
<multistatus xmlns="DAV:">
  <response>
    <href>http://localhost/testfile.txt</href>
    <propstat>
      <prop>
        <ns1:prop1 xmlns:ns1="examplens:">Only opaque property</ns1:prop1>
      </prop>
      <status>HTTP/1.1 200 Ok</status>
    </propstat>
    <propstat>
      <prop>
        <ns1:prop2 xmlns:ns1="examplens:" />
      </prop>
      <status>HTTP/1.1 404 Not Found</status>
    </propstat>
  </response>
</multistatus>
