From 86a7c2361bcabc25d4482da90e2bcf89683abf99 Mon Sep 17 00:00:00 2001 From: ZhouYongyou <128128010+zhouyongyou@users.noreply.github.com> Date: Tue, 4 Nov 2025 22:41:35 +0800 Subject: [PATCH] fix(decision): handle fullwidth JSON characters from AI responses MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Extends fixMissingQuotes() to replace fullwidth brackets, colons, and commas that Claude AI occasionally outputs, preventing JSON parsing failures. Root cause: AI can output fullwidth characters like ［｛：， instead of [{ :, Error: "JSON 必须以 [{ 开头，实际: [ {"symbol": "BTCU" Fix: Replace all fullwidth JSON syntax characters: - ［］ (U+FF3B/FF3D) → [] - ｛｝ (U+FF5B/FF5D) → {} - ： (U+FF1A) → : - ， (U+FF0C) → , Test case: Input: ［｛\"symbol\"：\"BTCUSDT\"，\"action\"：\"open_short\"｝］ Output: [{\"symbol\":\"BTCUSDT\",\"action\":\"open_short\"}] 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- decision/engine.go | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) diff --git a/decision/engine.go b/decision/engine.go index df48d534..9a75df38 100644 --- a/decision/engine.go +++ b/decision/engine.go @@ -459,12 +459,22 @@ func extractDecisions(response string) ([]Decision, error) { return decisions, nil } -// fixMissingQuotes 替换中文引号为英文引号（避免输入法自动转换） +// fixMissingQuotes 替换中文引号和全角字符为英文引号和半角字符（避免AI输出全角JSON字符导致解析失败） func fixMissingQuotes(jsonStr string) string { + // 替换中文引号 jsonStr = strings.ReplaceAll(jsonStr, "\u201c", "\"") // " jsonStr = strings.ReplaceAll(jsonStr, "\u201d", "\"") // " jsonStr = strings.ReplaceAll(jsonStr, "\u2018", "'") // ' jsonStr = strings.ReplaceAll(jsonStr, "\u2019", "'") // ' + + // ⚠️ 替换全角括号、冒号、逗号（防止AI输出全角JSON字符） + jsonStr = strings.ReplaceAll(jsonStr, "［", "[") // U+FF3B 全角左方括号 + jsonStr = strings.ReplaceAll(jsonStr, "］", "]") // U+FF3D 全角右方括号 + jsonStr = strings.ReplaceAll(jsonStr, "｛", "{") // U+FF5B 全角左花括号 + jsonStr = strings.ReplaceAll(jsonStr, "｝", "}") // U+FF5D 全角右花括号 + jsonStr = strings.ReplaceAll(jsonStr, "：", ":") // U+FF1A 全角冒号 + jsonStr = strings.ReplaceAll(jsonStr, "，", ",") // U+FF0C 全角逗号 + return jsonStr }
