Connecting to Local Files

Set the URI to a folder containing JSON files.

Below is an example connection string:

URI=C:\folder1\file.json;

Connecting to HTTP JSON Streams

Set the URI to the HTTP or HTTPS URL of the JSON resource you want to access as a table. Set AuthScheme to use the following authentication types. The 本製品 also supports OAuth authentication; see OAuth の使用 for more information.

  • HTTP:To use HTTP Basic or Digest, set the User and Password and set the corresponding AuthScheme. Set CustomHeaders if you need access to the request headers. Set CustomUrlParams to modify the URL query string.
  • Windows (NTLM): Set the Windows User and Password to connect and set AuthScheme to "NTLM".
  • Kerberos and Kerberos Delegation: To authenticate with Kerberos, set the User and Password and set AuthScheme to NEGOTIATE. To use Kerberos Delegation, set AuthScheme to KERBEROSDELEGATION.

For example:

URI=http://www.host1.com/streamname1;AuthScheme=BASIC;User=admin;Password=admin

Connecting to Amazon S3

Set the URI to a JSON document in a bucket. Additionally, set the following properties to authenticate:

  • AWSAccessKey: Set this to an Amazon Web Services Access Key (a username).
  • AWSSecretKey: Set this to an Amazon Web Services Secret Key.
For example:
URI=s3://bucket1/folder1/file.json; AWSAccessKey=token1; AWSSecretKey=secret1; AWSRegion=OHIO;
Optionally, specify AWSRegion in addition.

Note: It is also possible to connect to S3-compatible services by specifying its base Url. For example, if the Url conn prp is set to http://s3.%region%.myservice.com and Region is region-1, then we will generate request URLs like https://s3.region-1.myservice.com/bucket/... (or like https://bucket.s3.region-1.myservice.com/..., if the UseVirtualHosting property is true).

Connecting to Oracle Cloud Object Storage

Set the URI to a JSON document in a bucket. Additionally, set the following properties to authenticate:

  • AccessKey: Set this to an Oracle cloud Access Key.
  • SecretKey: Set this to an Oracle cloud Secret Key.
  • OracleNamespace: Set this to an Oracle cloud namespace.
For example:
URI=os://bucket/remotePath/; AccessKey=token1; SecretKey=secret1; OracleNamespace=myNamespace; Region=us-ashburn-1;
Optionally, specify Region in addition.

Connecting to Wasabi

Set the URI to a JSON document in a bucket. Additionally, set the following properties to authenticate:

  • AWSAccessKey: Set this to a Wasabi Access Key (a username)
  • AWSSecretKey: Set this to a Wasabi Secret Key.
Optionally, specify AWSRegion in addition.

For example:

URI=wasabi://bucket1/folder1/file.json; AWSAccessKey=token1; AWSSecretKey=secret1; AWSRegion=OHIO;

Connect to Azure Blob Storage

Set the URI to the name of your container and the name of the blob. Additionally, set the following properties to authenticate:

  • AzureAccount: Set this to the account associated with the Azure blob.
  • AzureAccessKey: Set this to the access key associated with the Azure blob.
For example:
URI=azureblob://mycontainer/myblob/; AzureAccount=myAccount; AzureAccessKey=myKey;

Connect to Azure Data Lake Store Gen 2

Set the URI to the name of the file system, the name of the folder which contacts your JSON files, and the name of a JSON file. Additionally, set the following properties to authenticate:

  • AzureAccount: Set this to the account associated with the Azure data lake store.
  • AzureAccessKey: Set this to the access key associated with the Azure data lake store.
For example:
  URI=abfs://myfilesystem/folder1/file.json; AzureAccount=myAccount; AzureAccessKey=myKey;
  URI=abfss://myfilesystem/folder1/file.json; AzureAccount=myAccount; AzureAccessKey=myKey;

Connecting to Box

Set the URI to the path to a JSON file. To authenticate to Box, use the OAuth authentication standard. See Box への接続 for an authentication guide.

For example:

URI=box://folder1/file.json; InitiateOAuth=GETANDREFRESH; OAuthClientId=oauthclientid1; OAuthClientSecret=oauthcliensecret1; CallbackUrl=http://localhost:12345;

Connecting to Dropbox

Set the URI to the path to a JSON file. To authenticate to Dropbox, use the OAuth authentication standard. See Dropbox への接続 for an authentication guide. You can authenticate with a user account or a service account. In the user account flow, you do not need to set any connection properties for your user credentials, as shown in the connection string below:

URI=dropbox://folder1/file.json; InitiateOAuth=GETANDREFRESH; OAuthClientId=oauthclientid1; OAuthClientSecret=oauthcliensecret1; CallbackUrl=http://localhost:12345;

Connecting to SharePoint Online SOAP

Set the URI to a document library containing JSON files. To authenticate, set User and Password and SharepointUrl.

For example:

URI=sp://Documents/folder1; User=user1; Password=password1; SharepointUrl=https://subdomain.sharepoint.com;

Connecting to SharePoint Online REST

Set the URI to a document library containing JSON files. SharepointUrl is optional. If not provided, the driver will work with the root drive. To authenticate, use the OAuth authentication standard.

For example:

URI=sp://Documents/folder1; InitiateOAuth=GETANDREFRESH; SharepointUrl=https://subdomain.sharepoint.com;

Connecting to FTP

Set the URI to the address of the server followed by the path to the JSON file. To authenticate, set User and Password.

For example:

URI=ftps://localhost:990/folder1/file.json; User=user1; Password=password1; 

Connecting to Google Cloud Storage

Set the URI to the path to the name of the file system, the name of the folder which contains your JSON files, and the name of a JSON file. To authenticate to Google APIs, provide a ProjectId.

For example:

URI=gs://bucket/remotePath/; ProjectId=PROJECT_ID; 

Securing JSON Connections

By default, the 本製品 attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats to do so.
