    DropboxConnector

    一种ccesses the Dropbox file storage service to upload, download, or delete files and folders or list the contents of a folder from a Dropbox account.

    Jump to Configuration

    典型的使用

    • Manage datasets on Dropbox by uploading, downloading, and deleting files and folders
    • Transfer a file's contents (such as XML or raster) into or out of an attribute in FME
    • Read downloaded Dropbox data using theFeatureReader, or upload data written by theFeatureWriterto Dropbox
    • Retrieve file and folder names, paths, links and other information from Dropbox to use elsewhere in a workspace.

    How does it work?

    The DropboxConnector uses your Dropbox account credentials (either via a previously defined FME web connection, or by setting up a new FME web connection right from the transformer) to access the file storage service.

    Depending on your choice of actions, it will upload or download files, folders, and attributes;list information from the service;or delete items from the service.On uploads, link attributes are added to the output features.On List actions, file/folder information is added as attributes.

    关闭例：下载ing a dataset

    In this example, the DropboxConnector is used to download an Autodesk AutoCAD DWG file from Dropbox.一种fter creating a valid web connection to a Dropbox account (which can be done right in the Dropbox Account parameter), the path and filename to download both from and to are entered.

    s

    一种FeatureReaderis added to read the newly downloaded dataset.Here, the ParcelLines feature type will be further processed elsewhere in the workspace.

    By executing the download here in the workspace, the source dataset will be refreshed every time the workspace is run.

    关闭例：下载ing and using a raster as an attribute

    In this example portion of a workspace, the DropboxConnector is used to download a raster orthoimage from Dropbox into an attribute.

    该文件是从Dropbox的阅读，其内容作为Blob存储的属性。然后，RasterReplacer用于团块解释成可用光栅格式。

    这两个变压器的组合，避免了下载图片到本地存储和重新阅读。类似的技术可用于点云的文件，使用PointCloudReplacer变压器。

    Usage Notes

    This transformer cannot be used to directly move or copy files between different Dropbox locations.However, multiple DropboxConnectors can be used to accomplish these tasks.

    The performance of this transformer is dependent on the amount of memory allocated to the Java Virtual Machine (JVM).The following environment variables allow you to specify memory available to Java Plugins:

    • FME_JVM_MIN_HEAP_SIZE: Initial heap size for initializing the JVM.If unset, the default value is 1024K.
    • FME32_JVM_MIN_HEAP_SIZE: Same as FME_JVM_MIN_HEAP_SIZE, but applies to 32-bit FME Desktop on Windows, and if set, takes precedence over FME_JVM_MIN_HEAP_SIZE.

    These variables must be set in multiples of 1024 and greater than 1 MB.To indicate kilobytes, megabytes, or gigabytes, appendkorK,morM, orgorGrespectively.For example, any of these values is acceptable:

    6291456

    6144k

    6m

    • FME_JVM_MAX_HEAP_SIZE: Maximum heap size for initializing the JVM.If unset, the default value is 16384K.
    • FME32_JVM_MAX_HEAP_SIZE: Same as FME_JVM_MAX_HEAP_SIZE, but applies to 32-bit FME Desktop on Windows, and if set, takes precedence over FME_JVM_MAX_HEAP_SIZE.

    These variables must be set in multiples of 1024 and greater than 2 MB.To indicate kilobytes, megabytes, or gigabytes, appendkorK,morM, orgorGrespectively.For example, any of these values is acceptable:

    83886080

    81920k

    80m

    注意：To pass additional parameters used by FME to the Java Virtual Machine, use the JAVA_TOOL_OPTIONS environment variable.

    这台变压器的输出将取决于Dropbox的行动进行改变。

    • 后上传行动网址的文件可以保存到可共享的链接并直接下载链接的属性。
    • 一种下载动作可以保存到一个文件或属性。
    • 一种删除行动将节省删除，被删除的文件计数属性的文件/文件夹的数量。
    • 最后，名单行动将输出在指定的路径中找到的每个文件/文件夹中的新功能。每一个的这些新功能将具有属性列出各种条关于对象的信息。

    导致操作失败的特点是通过此端口输出。一个fme_rejection_code属性，具有值ERROR_DURING_PROCESSING，将被添加，具有更多的描述性沿fme_rejection_message属性包含更具体的细节，以失败的原因。

    注意：如果一个功能进来的DropboxConnector已经有一个值fme_rejection_code，该值将被删除。

    被拒绝的功能处理：可以设置为终止翻译或继续当它遇到被拒绝的功能运行。此设置既可以作为默认FME选项并作为工作区参数。

    Editing Transformer Parameters

    Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace.More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers.To access a menu of these options, clickbeside the applicable parameter.For more information, seeTransformer Parameter Menu Options。

    Defining Values

    There are several ways to define a value for use in a Transformer.The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters.There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.
