按关键字搜索商品API接口搜索关键字，显示商品总数，标题，图片，优惠价参数等

按关键字搜索商品API接口通常用于根据关键字搜索商品，并返回商品的相关信息。以下是一个示例，说明如何使用Python调用按关键字搜索商品API接口。

item_search-按关键字搜索淘宝商品

公共参数

API接口请求地址:调用key

名称	类型	必须	描述
key	String	是	调用key（必须以GET方式拼接在URL中）
secret	String	是	调用密钥
api_name	String	是	API接口名称（包括在请求地址中）[item_search,item_get,item_search_shop等]
cache	String	否	[yes,no]默认yes，将调用缓存的数据，速度比较快
result_type	String	否	[json,jsonu,xml,serialize,var_export]返回数据格式，默认为json，jsonu输出的内容中文可以直接阅读
lang	String	否	[cn,en,ru]翻译语言，默认cn简体中文
version	String	否	API版本

请求参数

请求参数：q=女装&start_price=0&end_price=0&page=1&cat=0&discount_only=&sort=&page_size=&seller_info=&nick=&ppath=&imgid=&filter=

参数说明：q:搜索关键字
sort:排序[bid,_bid,bid2,_bid2,_sale,_credit]
  (bid:总价,bid2:商品价格,sale:销量,credit信用,加_前缀为从大到小排序)
page:页数

我们可以编写以下Python代码来调用商品详情API接口： 

# coding:utf-8
"""
Compatible for python2.x and python3.x
requirement: pip install requests
"""
from __future__ import print_function
import requests
# 请求示例 url 默认请求参数已经做URL编码
url = "https://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=&seller_info=&nick=&ppath=&imgid=&filter="
headers = {"Accept-Encoding": "gzip","Connection": "close"
}
if __name__ == "__main__":r = requests.get(url, headers=headers)json_obj = r.json()print(json_obj)

请注意，您需要将num_iid和api_key替换为实际的id和apisecret。此外，您可能需要根据实际的API响应格式调整代码中的键名。
