以JSON格式查看SharePoint 2010列表

Question

我准备使用Timeglider创建时间轴。一个要求是数据必须采用JSON格式。对我的一个要求是它需要成为客户端，因为我无法访问服务器或中央管理员。

当我尝试做http://webname/_vti_bin/ListData.svc/listname但是当我发出访问权限时出现错误http://webname/subsite/_vti_bin/ListData.svc/listname我没有问题拉取数据。

我的情况是列表在TLD上。我试图关注此帖How to retrieve a json object from a sharepoint list，但它与SP 2007有关。

Answer 1

要在SharePoint 2007,2010等平台上实现纯JSON支持，请查看此项目http://camelotjson.codeplex.com/。它要求将商业产品Camelot .NET Connector安装在服务器上。

如果你不喜欢去商业你可以诉诸sp.js图书馆，这里是我写的一个小例子，享受！

// Object to handle some list magic 
var ListMagic = function() { 
    /* Private variables */ 
    var that = this; 
    var clientContext = SP.ClientContext.get_current(); 
    var web = clientContext.get_web(); 
    var lists = web.get_lists(); 

    /** 
    * Method to iterate all lists 
    */ 
    that.getLists = function() { 

     clientContext.load(lists); 
     clientContext.executeQueryAsync(execute, getFailed); 

     function execute() { 
      var listEnumerator = lists.getEnumerator(); 
      while (listEnumerator.moveNext()) { 
       var l = listEnumerator.get_current(); 
       // TODO! Replace console.log with actual routine 
       console.log(l.get_title()); 
      } 
     } 

     function getFailed() { 
      // TODO! Implement fail management 
      console.log('Failed.'); 
     } 
    }; 


    /** 
    * Method to iterate all fields of a list 
    */ 
    that.getFields = function (listName) { 

     // Load list by listName, if not stated try to load the current list 
     var loadedList = typeof listName === 'undefined' ? lists.getById(SP.ListOperation.Selection.getSelectedList()) : that.lists.getByTitle(listName); 
     var fieldCollection = loadedList.get_fields(); 

     clientContext.load(fieldCollection); 
     clientContext.executeQueryAsync(execute, getFailed); 

     function execute() { 
      var fields = fieldCollection.getEnumerator(); 
      while (fields.moveNext()) { 
       var oField = fields.get_current(); 

       // TODO! Replace console.log with actual routine 
       var listInfo = 'Field Title: ' + oField.get_title() + ', Field Name: ' + oField.get_internalName(); 
       console.log(listInfo); 
      } 
     } 

     function getFailed() { 
      // TODO! Implement fail management 
      console.log('Failed.'); 
     } 
    }; 


    /** 
    * Method to get a specific listitem 
    */ 
    that.getListItem = function (itemId) { 

     var loadedList = lists.getById(SP.ListOperation.Selection.getSelectedList()); 
     var spListItem = loadedList.getItemById(itemId); 

     clientContext.load(spListItem); 
     clientContext.executeQueryAsync(execute, getFailed); 


     function execute() { 
      // TODO! Replace console.log with actual routine 
      //spListItem.get_fieldValues() 
      console.log(spListItem.get_fieldValues()["Title"]); 
     } 

     function getFailed() { 
      // TODO! Implement fail management 
      console.log('Failed.'); 
     } 
    }; 

    /** 
    * Method to fake an init (optional) 
    */ 
    that.init = function() { 
     // Run any init functionality here 
     // I.e 
     that.getFields("Tasks"); 
    }; 

    return that; 
}; 

// In case of no jquery use window.onload instead 
$(document).ready(function() { 
    ExecuteOrDelayUntilScriptLoaded(function() { 
     var sp = new ListMagic(); 
     sp.init(); 
    }, 'sp.js'); 
}); 

Answer 2

就我个人而言，我制作HttpHandlers。我将它们安装在SharePoint isapi文件夹和GAC中，我可以像调用owssvr.dll一样调用它们。 http://servername/_vti_bin/myhttphandelr.dll 传递查询字符串变量或从jquery ajax调用它。您可以使用httpcontext并从中创建spcontext，并可以访问SharePoint中当前位置的各种信息。然后你可以javascriptserialize这些对象并将它们作为JSON传递。寻找一些代码...挂上...我不能把所有的代码，但这应该让你关闭。我用它来添加一个子菜单到上下文菜单，以允许用户删除或重命名一个文件，如果他们上传到一个库，它是版本1.0，并从库中收集文件，并创建一个带有选定文件的eml文件（s）作为附件。我们不会给我们的用户正常删除权限。需要指出的是，现在您可以使用SharePoint所需的信息创建一个类，并将其作为JSON传递。这是我唯一的缺点，如果你对dll进行任何更改，iisreset是必需的。 无论如何，我每天晚上都会安排一次iisreset，以保持新鲜感并避免内存膨胀。我第二天来，我的变化就在那里。最酷的是，spcontext具有关于调用SharePoint的当前位置的信息。所以，http://servername/_vti_bin/myhttphandelr.dll vs http://servername/subsite/library/_vti_bin/myhttphandelr.dll

我可能会添加。不要尝试序列化SharePoint对象。一个是巨大而复杂的物体。二，我不认为它们被标记为可序列化。只需创建自己的类，并使用SharePoint对象中需要的值填充它。
