图片上游 Base URL 不能指向本地协议代理

Error message

图片上游 Base URL 不能指向本地协议代理

What it means

open_image_proxy_request validates the upstream base URL before forwarding an image API (generations/edits) request. If the effective base URL (relay.upstream_base_url, falling back to relay_profile_base_url) resolves to a local protocol-proxy address (loopback/private scheme handled by this proxy itself), it refuses to proceed to prevent a proxy loop. The throw is a pre-flight safety guard in crates/codex-plus-core/src/protocol_proxy.rs.

Solutions

1. Set the image upstream base URL in the relay profile to a real remote endpoint (e.g. https://api.openai.com), not a localhost address
2. If upstream_base_url was intentionally blank, set relay_profile_base_url's source profile to a non-local URL
3. Restart/re-apply the profile so the generated config no longer points image requests at the local proxy

Example fix

// before
upstream_base_url = "http://127.0.0.1:8317"
// after
upstream_base_url = "https://api.openai.com"

let base = if relay.upstream_base_url.trim().is_empty() { crate::relay_config::relay_profile_base_url(&relay) } else { relay.upstream_base_url.trim().to_string() };
if base.trim().is_empty() || is_local_protocol_proxy_base_url(&base) { return Err("fix upstream base url first"); }

match open_image_generations_proxy_request(...) {
    Err(e) if e.to_string().contains("不能指向本地协议代理") => eprintln!("配置了本地代理地址，请改为远程上游 URL: {e}"),
    other => other?,
}

When it happens

Trigger: Calling open_image_generations_proxy_request or open_image_edits_proxy_request while the active relay profile's upstream_base_url (or the profile-derived base URL) points at localhost/127.0.0.1 or another local protocol proxy endpoint.

Common situations: User pasted a local relay address (e.g. http://127.0.0.1:port) into the '图片上游 Base URL' field of a relay profile, or relay_profile_base_url fallback resolved to the local proxy because the explicit upstream URL was blank.
