koa中GET請求參數獲取

好久沒使nodejs的koa框架，都忘記怎么獲取參數了，特此記錄下來

在koa中GET請求參數獲取

1.通過request接收

接受的方法有兩種：

　　query：返回的是格式化好的參數對象

　　querystring：返回的是請求字符串

async function test(ctx) {
    ctx.status = 200;
    let url = ctx.url;
    let request = ctx.request;
    let req_query = request.query;
    let req_queryString = request.querystring;
    let name = req_query.name;
    let text = req_query.text;
    ctx.body = {
        url: url,
        req_query: req_query,
        req_queryString: req_queryString,
        name: name,
        text: text
    }
}

2.直接從ctx中獲取Get請求

async function test(ctx) {
    ctx.status = 200;
    let url = ctx.url;
    let ctx_query = ctx.query;
    let ctx_querystring = ctx.querystring;
    let name = ctx_query.name;
    let text = ctx_query.text;
    ctx.body = {
        url: url,
        query: ctx_query,
        queryString: ctx_querystring,
        name: name,
        text: text
    }
}

返回結果

{

    "url": "/api/test?name=aaa&text=111",

    "query": {

        "name": "aaa",

        "text": "111"

    },

    "queryString": "name=aaa&text=111",

    "name": "aaa",

    "text": "111"

}
