为什么注册的时候总显示已经已经注册过了？

Question

明明没有注册过，调接口的时候总显示已经注册过了，到底是因为啥原因？
这个是注册页面的代码：

<div class="box2" v-show="msg === 1">
          <el-upload
            class="avatar-uploader"
            :action="imgapi"
            ref="upload"
            accept=".jpg, .jpeg, .png,"
            :show-file-list="false"
            :on-success="handsuccess"
            :before-upload="beforeAvatarUpload"
          >
            <img v-if="image" :src="forms.image" class="avatar" />
            <i v-else class="el-icon-plus avatar-uploader-icon"></i>
          </el-upload>
          <div class="box_common">
            <div class="box_common_left">
              <img src="./../../../assets/student/img/login_2.png" alt="" />
            </div>
            <input type="text" placeholder="用户名" v-model="forms.userName" />
          </div>

          <div class="box_common">
            <div class="box_common_left">
              <img src="./../../../assets/student/img/login_2.png" alt="" />
            </div>
            <input type="text" placeholder="账号" v-model="forms.account" />
          </div>

          <div class="box_common">
            <div class="box_common_left">
              <img src="./../../../assets/student/img/login_1.png" alt="" />
            </div>
            <input
              type="password"
              placeholder="密码"
              v-model="forms.password"
            />
          </div>

          <p class="box_nowcommon" @click="common()">注&nbsp;&nbsp;&nbsp;册</p>
        </div>

每次点注册按钮调用接口的时候network里总会显示已经注册过了

//注册
    common() {
      var reg = /[\u4E00-\u9FA5]|[\uFE30-\uFFA0]/g; //匹配汉字
      var ret = /^[a-zA-Z0-9]{6,}$/; //匹配数字和字母最少五次
      if (this.forms.image == "") {
        this.$notify.error({
          title: "错误",
          message: "头像不能为空",
          duration: 1500,
        });
      } else if (this.forms.userName == "") {
        this.$notify.error({
          title: "错误",
          message: "用户名不能为空",
          duration: 1500,
        });
      } else if (this.forms.account == "") {
        this.$notify.error({
          title: "错误",
          message: "账号不能为空",
          duration: 1500,
        });
      } else if (this.forms.password == "") {
        this.$notify.error({
          title: "错误",
          message: "密码不能为空",
          duration: 1500,
        });
      } else if (reg.test(this.account)) {
        this.$notify.error({
          title: "错误",
          message: "账号不能出现汉字",
          duration: 1500,
        });
      } else {
        if (ret.test(this.forms.account)) {
          if (ret.test(this.forms.password)) {
            this.axios
            // .studentCommon(this.forms)
            .studentShopCommon({
              userId:this.user_id,
              trainId:this.train_id,
              image:this.forms.image,
              userName:this.forms.userName,
              account:this.forms.account,
              password:this.forms.password,
            })
            .then((res) => {
              if (res.data.data !=-1) {
                  this.$message({
                    type: "success",
                    message: "注册成功！！",
                  });
                  this.forms="";  
              }
            })
            .catch((err) =>{})
          }else{
            this.$notify.error({
                  title: "错误",
                  message: "密码不能少于6位",
                  duration: 1500,
                });
          }
        }else{
           this.$notify.error({
                title: "错误",
                message: "用户名不能少于6位",
                duration: 1500,
              });
        }
      }
    },

可是该传的值我已经传过去了

Answer 1

这不得问你们后端啊，搁这问我们咋知道咋回事儿？

Answer 2

要自信一点, 你能确定没注册，但是后端返回已注册。
那就去找后端啊, 并不是一有问题就是自已的问题~~
