这个题目可能表达不明白，就是表达内的数据都填写了通过rules验证发现表单内根本没有数据，表单是空的。

这是表单 类型是insertBook，填写基本的图书信息

<el-form
      :rules="rules"
      ref="insertBook"
      :model="insertBook"
      label-width="80px"
    >
      <el-row>
        <el-col :span="7"
          ><el-form-item label="书名" prop="bname">
            <el-input

这是写在data中的insertBook类型数据 以及rules验证规则

data() {
    return {
      sampleD: "value",
      insertBook: {
        books: {
          baddress: null,
          bclass: "xiandai",
          bfloor: null,
          bid: null,
          bname: null,
          bnum: null,
          bpress: null,
          bprice: null,
          bstate: "keyi",
          bwriter: null,
        },
        booksNote: {
          bid: 5,
          bnum: "",
          bsource: null,
          insertTime: "",
          insertAdmin: "",
        },
      },
      rules: {
        bname: [{ required: true, message: "请填写书名", trigger: "blur" }],
        bwriter: [{ required: true, message: "请填写作者", trigger: "blur" }],
        bpress: [{ required: true, message: "请填写出版社", trigger: "blur" }],
        bfloor: [
          { required: true, message: "请填写存放楼层", trigger: "blur" },
          { validator: isInteger, trigger: "blur" },
        ],
        baddress: [
          { required: true, message: "请填写存放书架", trigger: "blur" },
        ],
        bnum: [{ required: true, message: "请填写书号", trigger: "blur" }],
        bprice: [{ required: true, message: "请填写价格", trigger: "blur" }],
        bsource: [{ required: true, message: "请填写来源", trigger: "blur" }],
        bstate: [{ required: true, message: "请选择书籍状态", trigger: "blur" }],
        bclass: [{ required: true, message: "请选择书籍分类", trigger: "blur" }],
      },
    };
  },

这是method中的插入书籍请求

insertBooks() {
      this.$refs.insertBook.validate((valid) => {
        if (valid) {
          this.$http({
            method: "post",
            url: "/library/books/insertBook",
            data: this.insertBook,
          }).then(
            (res) => {
              this.$message.warning(JSON.stringify(res.data));
            },
            (error) => {
              console.log(" request error : " + error.response.status);
            }
          );
        } else {
          this.$message.warning(this.insertBook);
          // this.$message.warning("验证不通过请重新填写表单");
        }
      });
    },

我仔细地检查了每一个标签 并没有落下任何一个prop
然而

我填写了数据vue中也提示有数据，我通过请求中的else this.$message.warning(this.insertBook);
发现输出insertBook中的数据，输出为空

解决了 卧槽 真厉害呀
就是我的书名类型全称应该是insertBook.books.bname （就是v-model）
要写成 prop=‘books.bname’
rule:{
[‘books.bname’]:[{ required: true, message: “请填写书名”, trigger: “blur” }]
}
这样就好使了 hhhh
