--- author: 微信登录修复会话 created_at: 2026-06-03 purpose: 微信小程序登录修复 spec 的实施计划（TDD + 频繁 commit） --- # 微信小程序登录修复实施计划 > **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking. **Goal:** 修复微信小程序登录 `text/plain` 错误（Spring RestTemplate 默认 UA 触发 WAF 拦截），移除 `app-id` / `app-secret` 硬编码，提供完整日志 + 友好错误提示 **Architecture:** 用 `RestTemplateBuilder` + `BufferingClientHttpRequestFactory` 包装统一 RestTemplate Bean；新增 Interceptor（脱敏日志）+ ErrorHandler（4xx/5xx 不抛异常）+ Exception（业务异常）三件套；`code2Session` 改五步防御（网络 → HTTP status → content-type → JSON 解析 → 业务错误码）；`GlobalExceptionHandler` 新增 `WechatApiException` handler 返回脱敏的友好提示 **Tech Stack:** Spring Boot 2.7.18 + Java 17 + Spring RestTemplate + Spring `BufferingClientHttpRequestFactory` + Lombok + JUnit 5 + Mockito + Maven 3.6+ --- ## 文件结构 | 状态 | 文件 | 责任 | 行数 | |---|---|---|---| | 重写 | `server/src/main/java/com/emotion/config/RestTemplateConfig.java` | 统一 RestTemplate Bean（User-Agent + 超时 + 拦截器 + 错误处理） | 13 → 40 | | 新增 | `server/src/main/java/com/emotion/interceptor/WechatApiLoggingInterceptor.java` | 请求/响应日志（INFO）+ 脱敏 body（DEBUG） | 60 | | 新增 | `server/src/main/java/com/emotion/config/WechatResponseErrorHandler.java` | 4xx/5xx 不抛异常 | 30 | | 新增 | `server/src/main/java/com/emotion/exception/WechatApiException.java` | 业务异常类（HTTP 风格 code + rawBody） | 30 | | 重写 | `server/src/main/java/com/emotion/service/impl/WechatMiniProgramServiceImpl.java` | `code2Session` 五步防御 | 49 → 90 | | 修改 | `server/src/main/java/com/emotion/exception/GlobalExceptionHandler.java` | 新增 `handleWechatApiException` + 脱敏日志 | +25 | | 修改 | `server/src/main/resources/application.yml` | 移除 `app-id` / `app-secret` 硬编码默认值 | 2 行 | **总计**：2 重写 + 3 新增 + 2 修改，约 280 行 Java + 2 行 YAML --- ## 前置条件检查（开始 Task 1 前执行） ```bash cd "G:\IdeaProjects\emotion-museun" git status # 确认在 master 分支 git log --oneline -1 # 确认最新 commit 是 82c308b ls server/src/main/java/com/emotion/exception/ # 确认 GlobalExceptionHandler.java 存在 ls server/src/main/java/com/emotion/config/ # 确认 RestTemplateConfig.java 存在 ls server/src/main/java/com/emotion/service/impl/ # 确认 WechatMiniProgramServiceImpl.java 存在 ``` 期望：全部存在，工作树只有 spec 文件修改（无业务代码污染） --- ## Task 1: 创建 WechatApiException 异常类 **Files:** - Create: `server/src/main/java/com/emotion/exception/WechatApiException.java` - [ ] **Step 1.1: 写入 WechatApiException.java** 完整内容（创建文件并写入）： ```java package com.emotion.exception; import lombok.Getter; /** * 微信 API 业务异常 * *

    *
  1. 显式重写 hasError() 委托父类判断（4xx/5xx → true），让 handleError() 在错误时被调用

  2. handleError() 不抛 RestClientException，由业务层（WechatMiniProgramServiceImpl） * 根据 status code 判断如何处理

设计要点： *

    2. *
  2. 显式设置 User-Agent 为 Mozilla/5.0，绕过 WAF / CloudFlare 对 Java/* 默认 UA 的拦截
    3. *
  3. 显式设置连接 / 读取超时，避免线程被 hang 住
    4. *
  4. 加 StringHttpMessageConverter(UTF_8) 支持 text/plain 响应
    5. *
  5. 加 WechatApiLoggingInterceptor 记录请求 / 响应（脱敏）
    6. *
  6. 加 WechatResponseErrorHandler 4xx/5xx 不抛异常
