vue後臺系統管理專案之角色許可權分配管理功能(範例詳解)

2022-09-28 14:00:35

vue後臺系統管理專案：

技術選型：vue + element-ui
選單許可權管理模組功能

角色列表查詢，通過（角色名稱；角色編號；狀態：啟用、禁用）進行角色資料搜尋。
查詢、重置、新建角色功能
角色列表分頁實現
角色編輯，角色禁用，角色刪除操作
新建角色功能包括對角色名稱、選單許可權資訊的儲存提交

角色許可權分配管理功能

element-ui tree元件注意事項
node-key 每個樹節點用來作為唯一標識的屬性，整棵樹應該是唯一的
check-strictly 在顯示核取方塊的情況下，是否嚴格的遵循父子不互相關聯的做法，預設為 false

expand-on-click-node 是否在點選節點的時候展開或者收縮節點，預設值為 true，如果為 false，則只有點箭頭圖示的時候才會展開或者收縮節點。

check-change 節點選中狀態發生變化時的回撥，共三個引數，依次為：傳遞給data屬性的陣列中該節點所對應的物件、節點本身是否被選中、節點的子樹中是否有被選中的節點

role.vue模組

1.查詢重置搜尋

 <!-- 查詢重置搜尋 -->
    <el-form :model="ruleForm" ref="ruleForm" label-width="100px" class="demo-ruleForm" size="35">
      <el-row>
        <el-col :span="8">

2.table列表

<!--列表-->
    <el-table :data="tableData" border highlight-current-row v-loading="loading" element-loading-text="拼命載入中"
              style="width: 100%;height:auto;" :header-cell-style="{textAlign: 'center',background:'#fafafa'}"

  addRole,//新增角色
  allMenu,//選單列表
  disableRoleEnable,//禁用角色
  roleEditInfo,//角色編輯
  updateEditRole, //更新角色
  delSysRole//刪除角色
} from "../../api/userMG";

6.data定義

    return {
      loading: false, //是顯示載入
      isCanUse: false,
      dialogFormUser: false,
      checkStrictly: true,
      pagination: {
        page: 1,

      this.pagination.pageSize = val;
      this.pagination.page = 1;
      this.getRolePageFun();
    },

            id: row.id
          };
          disableRoleEnable(params)
            .then(res => {
              this.loading = false;
              if (res.code == 200) {
                console.log("開啟或者禁用");
                this.$message.success(
                  row.disable == true ? "啟用成功" : "禁用成功"

刪除角色，根據角色id

delFun(row) {
      this.$confirm(
        "是否將此使用者刪除?",
        "提示",

          confirmButtonText: "確定",
          cancelButtonText: "取消",
          type: "warning"
        }
      ).then(() => {
        delSysRole({id: row.id}).then(res =>{
          if (res.code === 200) {
            this.$message.success("操作成功");
            this.reload();
          }else {
            this.$message.warning(res.msg);
          }
        })
      }).catch(() => {
        this.$message.info("取消操作");
      })
    },

新增角色

addNewRole() {
      this.dialogFormUser = true;
      this.treeCheckedData = [];
      this.newRoleForm.roleName = "";
      this.roleId = "";
      this.getAllMenu();
    },

點選節點選中（節點選中狀態發生變化時的回撥）

handleChecked(data) {
      this.CheckedData = this.$refs.tree.getCheckedKeys();
    },

立即儲存角色

saveRole() {
      this.addRoleFun();
    },

點選編輯

handleEditClick(row) {
      console.log(row, "row");
      this.dialogFormUser = true;
      // /sysRole/info// 根據id檢視角色詳情
      roleEditInfo(row.id)
        .then(res => {
          this.loading = false;
          if (res.code == 200) {
            console.log(res.data, "根據id檢視角色詳情");
            this.getAllMenu();
            this.roleId = res.data.id;
            // this.newRoleForm.id = res.data.id;
            this.newRoleForm.roleName = res.data.roleName;
            let that = this;
            setTimeout(function () {
              res.data.menuIds.forEach(value => {
                that.$refs.tree.setChecked(value, true, false);
              });
            }, 1000);
          } else {
            this.$message.error(res.msg);
          }
        })
        .catch(err => {
          this.loading = false;
          this.$message.error("選單載入失敗，請稍後再試！");
        });
    },

新建角色

getRolePageFun() {
      this.ruleForm.pageNum = this.pagination.page;
      this.ruleForm.pageSize = this.pagination.pageSize;
      getRolePage(this.ruleForm)
        .then(res => {
          this.loading = false;
          if (res.code == 200) {
            console.log(res.data, "角色列表函數");
            this.tableData = res.data.records;
            this.pagination.total = res.data.total;
          } else {
            this.$message.error(res.msg);
          }
        })
        .catch(err => {
          this.loading = false;
          this.$message.error("選單載入失敗，請稍後再試！");
        });
    },

新增角色儲存函數

addRoleFun(newRoleForm) {
      console.log(this.newRoleForm, "this.newRoleForm");
      if (this.newRoleForm.roleName == "") {
        this.$message.error("角色名稱不能為空");
      } else if (this.CheckedData.length == 0) {
        this.$message.error("許可權不能為空");
      } else {
        if (this.roleId == "") {
          this.newRoleForm.menuIds = this.CheckedData;
          addRole(this.newRoleForm)
            .then(res => {
              this.loading = false;
              console.log(res, "新增角色");
              if (res.code == 200) {
                this.$message.success("新增成功");
                this.reload();
              } else {
                this.$message.error(res.msg);
              }
            })
            .catch(err => {
              this.loading = false;
              this.$message.error("選單載入失敗，請稍後再試！");
            });
        } else {
          this.newRoleForm.menuIds = this.CheckedData;
          this.newRoleForm.id = this.roleId;
          console.log(this.newRoleForm.menuIds, "id獲取");
          updateEditRole(this.newRoleForm)
            .then(res => {
              this.loading = false;
              console.log(res, "編輯角色");
              if (res.code == 200) {
                this.$message.success("編輯成功");
                this.reload();
              } else {

              }
            })
            .catch(err => {
              this.loading = false;
              this.$message.error("選單載入失敗，請稍後再試！");
            });
        }
      }
    },

獲取所有的選單函數

getAllMenu() {
      allMenu()
        .then(res => {
          this.loading = false;
          console.log(res.data, "獲取所有的選單");
          if (res.code == 200) {
            this.data2 = res.data;
          } else {
            this.$message.error(res.msg);
          }
        })
        .catch(err => {

        });
    }

8.created載入角色列表

created() {
    // 角色列表
    this.getRolePageFun();
  },
