# View

The `View` action retrieves a single document and returns it.

Type: Synchronous

Parameter Name | Description | Required
--- | --- | ---
`Config` | A base-64 encoded configuration. The configuration parameters that are set override the same parameters in the connector's configuration file. | No
`Identifier` | The identifier of the document to return. | Yes
`NoACI` | A Boolean value (default `TRUE`) that specifies whether to return just binary content. `TRUE` - Return binary content. `FALSE` - Return a normal ACI response with base-64 encoded content. | No
`Range` | View part of a file. For example, an application can request the first 100 KB of a large video file by setting `Range=bytes=0-99999`. The connector must support the `VIEW_RANGE` feature, and the repository must support the retrieval of content ranges, otherwise the parameter is ignored and the connector returns the entire file. | No
`WithMetadata` | A Boolean value (default `TRUE`) that specifies whether to return metadata in the action response when `NoACI=FALSE`. This parameter has no effect when `NoACI=TRUE`. The view action only returns metadata if the connector supports the `VIEW_WITH_METADATA` feature. | No
`Override_Config_Parameters` | Any other action parameters that you set override settings in the connector's configuration file. For example:
    /action=fetch&fetchaction=...
                 &[Section]Parameter=Value
where `[Section]` (optional) is the name of a configuration file section, `Parameter` is the name of a configuration parameter, and `Value` is the parameter value. | No

## Example

    http://localhost:7006/action=View&Identifier=PGlkIHQ9IkZpbGUiIHM9Ik1ZVEFTSyIgcj0iQzpcSURPTFxmaWxlLnR4dCIvPg==

## Response

The response is the binary content of the file, unless you have specified `NoACI=false`.

When you set the `Range` parameter to retrieve a content range, the connector responds with an HTTP 206 (Partial content) response code and the response includes the `Content-Range` response header. If either the connector or the repository does not support retrieval of content ranges, the connector returns an HTTP 200 response, without the `Content-Range` response header, and the response includes the entire file.

With `NoACI=false`, the connector returns XML and provides the content base-64 encoded:

    <autnresponse>
        <action>VIEW</action>
        <response>SUCCESS</response>
        <responsedata>
            <mime-type>application/octet-stream</mime-type>
            <filename>file.txt</filename>
            <content>Base64+encoded+file+content</content>
        </responsedata>
    </autnresponse>

When `NoACI=false` and you set the `Range` parameter to retrieve a content range, the connector returns an HTTP 200 response. In the XML, the `content` element can include a `range` attribute:

            <content range="bytes 0-9999/12345678">[base64 encoded binary data]</content>

When `NoACI=false` and the connector supports the `VIEW_WITH_METADATA` feature, it also returns document metadata, for example:

    <autnresponse>
      <action>VIEW</action>
      <response>SUCCESS</response>
      <responsedata>
        <reference>C:\file.txt</reference>
        <metadata>
          <CREATED>1499769017</CREATED>
          <FILESIZE>12</FILESIZE>
          <LASTACCESSED>1499769017</LASTACCESSED>
          <LASTCHANGED>1417178089</LASTCHANGED>
          <LASTMODIFIED>1357228211</LASTMODIFIED>
        </metadata>
        <mime-type>application/octet-stream</mime-type>
        <filename>file.txt</filename>
        <content>Base64+encoded+file+content</content>
    </responsedata>

The response includes the following elements:

- `reference` provides the document reference.
- `metadata` provides the metadata associated with the requested document.
- `page` elements (zero or more) provide text content, if the repository stores text alongside the document.
