Backend API. Server-side code: this runs in a Codename One backend, not in the app on the device.

public final class Web

  1. Object
  2. Web

Outbound HTTP and HTTPS for server-side binaries. Backed by libcurl, so TLS verification, redirects, chunked decoding and the system certificate store all come from a library that is maintained for the purpose.

Distinct from Http, which is a raw-socket plaintext client for the host runtime’s loopback control protocol. Use this one for anything real.

Certificate store. A dynamically linked build finds the system CA bundle. A fully static build has whatever the image provides, which for a scratch container is nothing - and TLS then fails with “unable to get local issuer certificate”. Ship a ca-certificates.crt and point curl at it with the CURL_CA_BUNDLE or SSL_CERT_FILE environment variable; both are read by libcurl itself, so no code here has to know about it.

Nested types

class Web.ResultAn outbound response: status, body, and libcurl’s message when it failed.
