Constructors

HTTP()

Initializes a new instance of the HTTP class.

Methods

addAttachmentData(Integer)

Adds the binary data in the Service attachment specified to the body of the request.

Declaration

Bool addAttachmentData(Integer attachmentId)

Parameters

Type	Name	Description
Integer	attachmentId	The ID of the Service attachment you want to upload.

Returns

Type	Description
Bool	True if the attachment was found; otherwise, false.

Remarks

Must be used together with POST, PUT or PATCH.

Many REST endpoints expect the content to be uploaded as binary data when adding files. You can use this method for doing that. automatically set the Content-Type header based on the content type recorded in the database for the attachment. If you want to override the Content-Type, be sure to set a Content-Type header after doing the addAttachmentData call.

Examples

#setLanguageLevel 3;

HTTP http;

if(http.addAttachmentData(24))
{
  Byte[] res = http.post("https://httpbin.org/post");
  if (!http.hasError())
    print(String(res));
  else
    print(http.getErrorMessage());

addBinaryData(Byte[])

Adds the binary data to the body of the request.

Declaration

Void addBinaryData(Byte[] binaryData)

Parameters

Type	Name	Description
Byte[]	binaryData	An array of Bytes containing the binary data you want to apply to the request body.

Returns

Type	Description
Void

Remarks

Must be used together with POST, PUT or PATCH.

Many REST endpoints expect the content to be uploaded as binary data when adding files. You can use this method for doing that. Normally, you also want to add a Content-Type header, indicating what kind of files this is.

Examples

#setLanguageLevel 3;

HTTP http;
Byte[] image = http.get("https://httpbin.org/image/png");
if (!http.hasError())
{
  http.addBinaryData(image);
  http.addHeader("Content-Type", "image/png");
  Byte[] res = http.post("https://httpbin.org/post");
  print(String(res));
}
else
{
  print(http.getErrorMessage());
}

addDocumentData(Integer)

Add the binary data in the document specified to the body of the request.

Declaration

Bool addDocumentData(Integer documentId)

Parameters

Type	Name	Description
Integer	documentId	The ID of the document you want to upload.

Returns

Type	Description

Remarks

Must be used together with POST, PUT or PATCH.

Many REST endpoints expect the content to be uploaded as binary data when adding files. You can use this method for doing that. automatically set the Content-Type header based on the extension of the document being added. If you want to override the Content-Type, be sure to set a Content-Type header after doing the addDocumentData call.

Examples

#setLanguageLevel 3;

HTTP http;

if(http.addDocumentData(24))
