如果你是一位电商运营者或者是想要进行1688平台产品调研的人员，你可能需要借助API接口来获取你所需要的信息。在这篇文章中，我们将会讨论如何通过关键词搜索API接口获取1688的商品详情。

第一步：获取API接口的授权信息 在使用API接口前，你需要先向1688申请API接口的授权信息。在申请之前，你需要先注册账号。

第二步：构建API接口调用请求 在获取授权之后，你需要根据相关接口文档，构建API接口调用请求。在这里，我们将以搜索商品接口为例，来讲解如何构建调用请求。

首先，你需要通过HTTP GET请求方式，来调用接口。相关调用信息如下：

请求参数：q=女装&start_price=0&end_price=0&page=1&cat=0&discount_only=&sort=&page_size=40&seller_info=no&nick=&seller_info=&nick=&ppath=&imgid=&filter=

参数说明：q:搜索关键字
cat:分类ID
start_price:开始价格
end_price:结束价格
sort:排序[bid,_bid,_sale,_credit]
  (bid:总价,sale:销量,credit信用,加_前缀为从大到小排序)
page:页数  page_size:每页宝贝数量，默认40
filter:额外的过滤参数，如：filter=filtId:1,2,3,4;activityType:1,2,3,4;city:天津;quantityBegin:1000
filtId 过滤：48小时发货,7+天包换,赠运费险,免费赊账;
activityType 优惠类型:包邮，产地货源，伙拼，手机专享价
city 地区：地区名
quantityBegin 起订量：数字

请求示例：

请求示例 url 默认请求参数已经URL编码处理
curl -i "https://api-gw.onebound.cn/1688/item_search/?key=<您自己的apiKey>&secret=<您自己的apiSecret>&q=女装&start_price=0&end_price=0&page=1&cat=0&discount_only=&sort=&page_size=40&seller_info=no&nick=&seller_info=&nick=&ppath=&imgid=&filter="

复制代码

第三步：接收API接口返回数据 在调用API接口之后，你将会收到相关的返回数据。在这里，我们将以json格式的返回结果为例，来讲解如何解析返回的数据。

返回示例：

"page": "1",
