错误

const result = z.string().safeParse(12); // { success: false, error: ZodError }
result.error.issues;

结果

[
  {
    expected: "string",
    code: "invalid_type",
    path: [],
    message: "Invalid input: expected string, received number",
  },
];

error map

z.string({
  error: (iss) => (iss.input === undefined ? "该字段为必填项。" : "无效输入。"),
});

当 error 是一个函数的时候，这个函数就是 error map

iss 拥有多种类型

iss.code; // 问题代码
iss.input; // 输入数据
iss.inst; // 产生该问题的模式/检查
iss.path; // 错误路径

全局错误定制

z.config({
  customError: (issus) => {
    const { path, code, expected, input } = issus;

    const valName = path?.join("、");

    if (input === undefined) {
      return `缺少 ${valName}`;
    }

    return `${valName} 应该为 ${expected}`;
  },
});
