The JSON value could not be converted to System.Nullable`1[System.Int32]报错的解决方案

问题:

调用接口,传入含有空值的int?型数据时,报如下错误:

The JSON value could not be converted to System.Nullable`1[System.Int32].

 

 

解决方式:

在调用接口之前,先把int?类型的

dec

属性值设为null值就可以了

            if (this.form.dec == "") {
              this.form.dec = null;
            }
            this.$axios
              .puts("/api/base/dec/" + this.form.id, this.form)
              .then((response) => {
                this.formLoading = false;
                this.$notify({
                  title: "成功",
                  message: "更新成功",
                  type: "success",
                  duration: 2000,
                });
              })
              .catch(() => {});
