python - 将 json 发布到露天网站 api 时出现错误 500

Question

我正在尝试 POST 到站点 api 来创建站点(显然:-))我发布以下内容:

payload={'description':'My description', 'visibility':'PUBLIC', 
'site-preset':'site-dashboard','title':'My Site name', "shortName":'my-site-name'}

如:

requests.post('http://<myserver>:8080/alfresco/service/api/sites',
auth=('admin','XXXXX'), data=json.dumps(payload))

在Python中。我收到了 500 错误，详细信息如下。我还需要在请求中添加什么才能使其正常工作？我找不到比 http://docs.alfresco.com/3.4/references/RESTful-SiteSitesPost.html 更进一步定义标题的文档我一直在使用这个例子:https://forums.alfresco.com/forum/developer-discussions/alfresco-api/create-site-alfresco-using-open-cmis-extension-07312013然而定义远不止于此。

下面清楚地表明 site.shortName 未定义，因此我应该如何在传递给站点 api 的 json 中定义 ShortName 以便 alfresco 站点 api 拾取它？也非常欢迎引用文档。

错误日志如下:

更新:我从那时起(部分感谢杰夫的回答)通过在存储库中创建一个网站，然后使用enable-site.get.js(谷歌它)来完成该过程，以编程方式创建了一个可用的网站。嘿，快点，一个可用的网站!关键是是在 javascript 层中调用 siteData.newPreset("site-dashboard", ) (如果我看到的是症状而不是实际的解决方案，请有人纠正我)以在 AVM 存储中实际生成所需的 xml，以便该站点可用。create-site 应该可以做到这一点；但是我还没有让它工作，因此需要两步过程。许多人似乎已经让 create-site 工作得很好。

创建站点需要 OAuth 身份验证。我发布的错误是由于没有传递正确格式的json导致的；我使用curl(按照Jeff Potts 的建议)和Postman(Chromium 应用程序)进行了重复测试。我现在是一只快乐的兔子(虽然我仍然不明白为什么 create-site 什么也没做，但无论如何；我有一个解决方案)

首先，请注意，成功调用此方法不会导致 Alfresco Share 中的站点正常运行。这一事实记录在 site.post Web 脚本文档中，可以在此处找到:

http://localhost:8080/alfresco/s/script/org/alfresco/repository/site/sites.post

如果您不打算创建功能性的 Alfresco Share 站点，但仍想在存储库层上创建站点文件夹结构(这就是此 Web 脚本的作用)，那么您需要提供的有效负载应如下所示:

{"title":"Test Site 1","visibility":"PUBLIC","description":"","sitePreset":"site-dashboard","shortName":"test-site-1"}

请注意，它使用的是“sitePreset”，而不是您最初使用的“site-preset”。

当我使用以下curl 语句对本地 4.2.f 服务器调用此函数时，我得到了成功的响应:

curl -uadmin:admin -X POST "http://localhost:8080/alfresco/service/api/sites" -H "content-type: application/json" -d@/var/tmp/site.json

至少从 4.2.f 开始，不支持以编程方式创建共享网站的方法。
