我想通过传递查询参数 dealType=PC 来过滤数据

【问题讨论】：

标签： angular api express httpserver json-server

【解决方案1】：

你可以在数组https://stackoverflow.com/a/45916177/13889280上使用filter方法

示例：

data = [{...}];
d = data[0]; // I assume only one data
pcDeals = d.deals.filter((x) => {return x.dealType == "PC"});

嗨 Yusuf 我在哪里添加 json-server 的方法？
