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(() => {});
