===== #### ===== * 今の例では単純に文字列置換で JSON を作っていますが、改行や " が含まれると壊れます。 * Gson を使って安全に JSON を生成する方法 が推奨です。 <syntaxhighlight lang="java">import com.google.gson.Gson; import java.util.HashMap; import java.util.Map; Gson gson = new Gson(); Map<String, Object> payload = new HashMap<>(); payload.put("model", "gpt-local"); payload.put("prompt", sourceCode); payload.put("cursor_offset", cursorOffset); payload.put("max_tokens", 200); String jsonRequest = gson.toJson(payload); </syntaxhighlight> * これで JSON のエスケープ問題は解決します。 ====== <syntaxhighlight lang="java">conn.setRequestProperty("Content-Type", "application/json; charset=UTF-8"); ====== </syntaxhighlight> ====== - /v1/completions に送る JSON が、サーバ側の仕様に合っているか確認 - 例:model フィールドが必須か - cursor_offset をサポートしているか ====== * もしサーバが OpenAI互換なら、prompt のみでもOKです。 ===== <syntaxhighlight lang="java">import com.google.gson.Gson; ===== // ... Gson gson = new Gson(); Map<String, Object> payload = new HashMap<>(); payload.put("model", "gpt-local"); payload.put("prompt", sourceCode); payload.put("cursor_offset", cursorOffset); payload.put("max_tokens", 200); String jsonRequest = gson.toJson(payload); HttpURLConnection conn = (HttpURLConnection) new URL(AI_SERVER_URL).openConnection(); conn.setDoOutput(true); conn.setRequestMethod("POST"); conn.setRequestProperty("Content-Type", "application/json; charset=UTF-8"); try (OutputStream os = conn.getOutputStream()) { os.write(jsonRequest.getBytes("UTF-8")); } </syntaxhighlight> * これで 400 エラーはほぼ確実に解消されます。
