Error message

不支持的类型

What it means

OauthController.getAuthSource throws RuntimeException('不支持的类型') only when oauthType is blank; for a non-blank but unknown provider, AuthSource.valueOf(type.toUpperCase()) instead throws IllegalArgumentException that escapes uncaught. The explicit message covers the blank-input case, but the more common unknown-provider path is not handled.

Solutions

1. Validate oauthType against factory.oauthList() before calling AuthSource.valueOf
2. Catch IllegalArgumentException and return HTTP 400 listing the supported providers
3. Guard the blank case explicitly with a 400 instead of a raw RuntimeException

Example fix

// before
private AuthSource getAuthSource(String type) {
    if (StrUtil.isNotBlank(type)) {
        return AuthSource.valueOf(type.toUpperCase());
    }
    throw new RuntimeException('不支持的类型');
}
// after
private AuthSource getAuthSource(String type) {
    if (StrUtil.isBlank(type) || !factory.oauthList().contains(type.toUpperCase())) {
        throw new IllegalArgumentException('不支持的类型: ' + type);
    }
    return AuthSource.valueOf(type.toUpperCase());
}

List<String> allowed = factory.oauthList();
String upper = oauthType == null ? '' : oauthType.toUpperCase();
if (StrUtil.isBlank(oauthType) || !allowed.contains(upper)) {
    return ResponseEntity.badRequest().body('unsupported type, allowed: ' + allowed);
}

try { AuthSource src = getAuthSource(oauthType); }
catch (RuntimeException e) { /* '不支持的类型' or IllegalArgumentException */ return ResponseEntity.badRequest().body(e.getMessage()); }

When it happens

Trigger: GET /oauth/login/{oauthType} or /{oauthType}/callback with an empty path variable, or with a provider name that is not a constant in the justauth AuthSource enum / not registered in the AuthRequestFactory.

Common situations: Hand-edited URLs; a provider disabled in configuration; a typo in the provider name; a justauth version whose AuthSource enum lacks the requested provider.
