Class MultipartEntityBuilder

java.lang.Object
org.apache.hc.client5.http.entity.mime.MultipartEntityBuilder

public class MultipartEntityBuilder extends Object
Builder for multipart HttpEntitys.

This class constructs multipart entities with a boundary determined by either a random UUID or an explicit boundary set via setBoundary(String).

IMPORTANT: it is responsibility of the caller to validate / sanitize content of body parts. For instance, when using an explicit boundary, it's the caller's responsibility to ensure the body parts do not contain the boundary value, which can prevent the consumer of the entity from correctly parsing / processing the body parts.

    • create

      public static MultipartEntityBuilder create()
    • setMode

    • setLaxMode

      public MultipartEntityBuilder setLaxMode()
    • setStrictMode

      public MultipartEntityBuilder setStrictMode()
    • setBoundary

      public MultipartEntityBuilder setBoundary(String boundary)
      Sets a custom boundary string for the multipart entity.

      If null is provided, the builder reverts to its default logic of using a random UUID.

      IMPORTANT: when setting an explicit boundary, it is responsibility of the caller to validate / sanitize content of body parts to ensure they do not contain the boundary value.

      Parameters:
      boundary - the boundary string, or null to use a random UUID.
      Returns:
