此变更引入了 API 破坏性变更。添加新字段 formFields 后,Lombok 的 @AllArgsConstructor 会将原有的 2 参数构造函数替换为 3 参数构造函数,这会导致所有直接使用 new CommonUploadParam(name, data) 的代码无法编译。
建议保持向后兼容性,可以采用以下方案之一:
- 手动添加一个 2 参数构造函数并标记为
@Deprecated - 使用
@Builder模式替代@AllArgsConstructor - 移除
@AllArgsConstructor并手动定义所需的构造函数
从当前 PR 的修改可以看出(WxOpenMaAuthServiceImpl 和 WxOpenUploadIcpMediaParam 需要显式传入 null),这确实是破坏性变更。
| /** | |
| /** | |
| * 为保持向后兼容保留的 2 参数构造函数。 | |
| * <p> | |
| * 仅设置文件参数名和上传数据,额外表单字段将为 {@code null}。 | |
| * | |
| * @param name 参数名,如:media | |
| * @param data 上传数据 | |
| * @deprecated 请使用包含 formFields 参数的构造函数或静态工厂方法 {@link #fromFile(String, File)}、{@link #fromBytes(String, String, byte[])} | |
| */ | |
| @Deprecated | |
| public CommonUploadParam(@NotNull String name, @NotNull CommonUploadData data) { | |
| this(name, data, null); | |
| } | |

文档声明"该功能向后兼容",但实际上存在 API 破坏性变更。由于添加了新字段 formFields,Lombok 的 @AllArgsConstructor 将 2 参数构造函数替换为 3 参数构造函数,导致直接使用 new CommonUploadParam(name, data) 的现有代码无法编译。
建议更新文档说明这一变更,或者修改 CommonUploadParam 类以保持真正的向后兼容性(例如添加 2 参数构造函数)。
| 该功能向后兼容,现有的不使用额外表单字段的代码无需修改即可继续工作。 | |
| - 对于通过 `fromFile`、`fromBytes` 等工厂方法创建 `CommonUploadParam` 的代码,本功能在行为层面是向后兼容的,现有代码无需修改即可继续工作。 | |
| - 如果之前直接使用构造函数(例如 `new CommonUploadParam(name, data)`)创建对象,由于新增了 `formFields` 字段,构造函数签名可能发生变化,升级后需要改为使用上述工厂方法或根据新构造函数签名调整代码。 |
| @Override | ||
| public MaAuthUploadResult upload(CommonUploadData data) throws WxErrorException { | ||
| String response = wxMaService.upload(OPEN_MA_AUTH_UPLOAD, new CommonUploadParam("media", data)); | ||
| String response = wxMaService.upload(OPEN_MA_AUTH_UPLOAD, new CommonUploadParam("media", data, null)); |

由于 CommonUploadParam 类的 API 破坏性变更(从 2 参数构造函数变为 3 参数构造函数),这里被迫显式传入 null 作为第三个参数。
这是设计问题的症状。如果 CommonUploadParam 保持向后兼容性(例如保留 2 参数构造函数或使用 Builder 模式),这里就不需要传入 null,代码会更清晰。
| CommonUploadMultiParam.NormalParam.builder().name("icp_order_field").value(icpOrderField).build() | ||
| )) | ||
| .uploadParam(new CommonUploadParam("media", media)) | ||
| .uploadParam(new CommonUploadParam("media", media, null)) |

问题
微信公众号上传永久视频素材时,需要同时POST文件和description表单字段(JSON格式的视频描述)。现有
CommonUploadParam只支持单文件上传,无法附加额外表单数据。变更
核心扩展
CommonUploadParam添加可选formFields属性(Map<String, String>)addFormField()方法支持链式调用HTTP客户端更新
更新所有4个执行器实现(OkHttp、Apache、HttpComponents、JoddHttp)以支持multipart请求中的额外表单字段
测试和文档
CommonUploadParamTest单元测试使用示例
兼容性
完全向后兼容。现有代码无需修改,表单字段为可选功能。
