您如何使用 EWS Managed API 和 ColdFusion 搜索收件箱？

Question

我们正在使用 ColdFusion 2016 并使用 EWS API 连接到交换。我已经设法从以下 post 中获取代码示例，但我无法弄清楚如何将 SearchFilter 与 findItems() 方法一起使用。 Why is the get action of cfexchangemail never returning?

service = createObject("Java", "microsoft.exchange.webservices.data.ExchangeService");
service.init();

version = createObject("Java", "microsoft.exchange.webservices.data.ExchangeVersion");
service.init(version.Exchange2010);

credentials = createObject("Java", "microsoft.exchange.webservices.data.WebCredentials");

credentials.init(yourusername, yourpassword);
service.setCredentials(credentials);

uri = createObject("Java", "java.net.URI");
uri.init("outlook webservices url");
service.setUrl(uri);
WellKnownFolderName=createObject("Java","microsoft.exchange.webservices.data.WellKnownFolderName");
result = service.FindItems(service.WellKnownFolderName.Inbox, CreateObject("java", "microsoft.exchange.webservices.data.ItemView").init(100));

for(item in result.getItems(){
    // ..loop through each field and store their value 
    // in query object or something...
}

所以基本上可以将此 Java 代码转换为 Coldfusion 吗？

ItemView view = new ItemView(10);
view.getOrderBy().add(ItemSchema.DateTimeReceived, SortDirection.Ascending);
view.setPropertySet(new PropertySet(BasePropertySet.IdOnly, ItemSchema.Subject, ItemSchema.DateTimeReceived));

FindItemsResults<Item> findResults =
    service.findItems(WellKnownFolderName.Inbox,
        new SearchFilter.SearchFilterCollection(
            LogicalOperator.Or, new SearchFilter.ContainsSubstring(ItemSchema.Subject, "EWS"),
        new SearchFilter.ContainsSubstring(ItemSchema.Subject, "API")), view);

service.loadPropertiesForItems(findResults, PropertySet.FirstClassProperties);
System.out.println("Total number of items found: " + findResults.getTotalCount());

for (Item item : findResults) {
    System.out.println(item.getSubject());
    System.out.println(item.getBody());
    // Do something with the item.
}

根据评论更新：

我不知道如何实例化 SearchFilter 或 SearchFilterCollection。我尝试创建一个 searchFilter 对象，但它没有可使用的属性。我一定是错过了什么。

CreateObject("java","microsoft.exchange.webservices.data.Sea‌rchFilter");

Answer 1

（不是完整答案，但评论太长）

难怪...那是很多的嵌套。我没有安装那个库，但如果是我，我会首先将它分解成单独的语句，每行一个 new 对象。从最里面的构造函数开始：

new SearchFilter.ContainsSubstring(
          ItemSchema.Subject
        , "API"
    )

您需要先创建 ItemSchema 的实例，才能访问 Subject 属性。查看 C# docs（没有可用的 javadoc）路径应该是这样的：

ItemSchema = createObject("java", "microsoft.exchange.webservices.data.ItemSchema");

之后继续创建 SearchFilter。注意到 class 名称中的句点 . 了吗？关键字 new 后跟一个 class 名称，包含句点，通常表示它是一个 inner class。内部 classes 需要特殊的语法，即 ParentClass$InnerClass。这样的事情应该有效：

APISubString = CreateObject("java","microsoft.exchange.webservices.data.SearchFilter$ContainsSubstring");
writeDump(APISubString );

如果有效，添加init()初始化对象：

  APISubString = CreateObject("java","microsoft.exchange.webservices.data.SearchFilter.ContainsSubstring").init(ItemSchema.Subject, "API");

然后移动到下一个最里面的对象：

new SearchFilter.ContainsSubstring(
           ItemSchema.Subject
          , "EWS"
    )

然后起泡沫，冲洗，对剩余的物体重复：

// ItemSchema.Subject is a static value and can be reused
EWSSubString = CreateObject("java","microsoft.exchange.webservices.data.SearchFilter.ContainsSubstring").init(ItemSchema.Subject, "EWS");

Answer 2

最终的工作结果是：

folderName = createObject("java", "microsoft.exchange.webservices.data.WellKnownFolderName");
itemView = CreateObject("java","microsoft.exchange.webservices.data.ItemView").init(10,0);
folderID = CreateObject("java","microsoft.exchange.webservices.data.FolderId").init(
        folderName.Inbox,
        mailBox
        );
sortDirection = CreateObject("java","microsoft.exchange.webservices.data.SortDirection");
basePropertySet = createObject("java", "microsoft.exchange.webservices.data.BasePropertySet");
propertyset = createObject("java", "microsoft.exchange.webservices.data.PropertySet");
itemSchema = createObject("java", "microsoft.exchange.webservices.data.ItemSchema");
searchFilterCollection = CreateObject("java","microsoft.exchange.webservices.data.SearchFilter$SearchFilterCollection");
logicalOperator = createObject("java", "microsoft.exchange.webservices.data.LogicalOperator");
subString1 = CreateObject("java","microsoft.exchange.webservices.data.SearchFilter$ContainsSubstring").init(
        itemSchema.Subject,
        "EWS"
        );
subString2 = CreateObject("java","microsoft.exchange.webservices.data.SearchFilter$ContainsSubstring").init(
        itemSchema.Subject,
        "API"
        );
searchFilterCollection.add(SubString1);
searchFilterCollection.add(SubString2);
searchFilterCollection.setLogicalOperator(LogicalOperator.Or);
bodyType = createObject("java", "microsoft.exchange.webservices.data.BodyType");
propertyset.add(itemSchema.Subject);
propertyset.add(itemSchema.DateTimeReceived);
propertyset.setBasePropertySet(basePropertySet.IdOnly);
propertyset.setRequestedBodyType(bodyType.HTML);
itemView.getOrderBy().add(itemSchema.DateTimeReceived, sortDirection.Ascending);
itemView.setPropertySet(propertyset);
viewResults = service.findItems(folderID, searchFilterCollection, itemView);
