在带有Python Requests（ebay）的网站上使用搜索功能

我正在尝试使用Requests库创建一个Python程序，该库在ebay上搜索他们输入的项目。可以使用请求库来执行Ebay搜索（或在任何网站上进行搜索），而不是对URL进行硬编码？

我认为您要在搜索元素中输入文字。根据{{​​3}}：

  

请求库是在Python中发出HTTP请求的事实上的标准。

我建议使用realpython来控制网站的源代码，例如在元素中输入文本并按网站上的按钮。

但是，如果您仍然想使用 requests ，请尝试找到处理搜索部分的api端点，并使用POST方法从中获取数据。

resp = requests.post(url)

我创建了一个Ebay开发人员帐户来访问API，然后编写了一个小脚本来搜索eBay上某商品的历史价格。保存它的电话是search.py​​并按如下方式调用它：

./ search.py​​“您要查找的ebay项目”

您可以根据自己的喜好更改itemFilter，当前设置为solditems，自10-10-2019起。完整列表在这里：https://developer.ebay.com/devzone/finding/callref/types/ItemFilterType.html

底部的注释显示了从Ebay返回的完整字段集，您可以选择所需的字段并将其添加到打印语句中。

此外，此脚本返回的内容将比商品的第一页还要多，并且每一页每天花费您的5,000个开发人员查询中的一个。无论我如何尝试，我都无法使其与沙盒一起使用。我相信Ebay沙箱坏了。
