Solve the troubles of crawler engineers, [Taobao 1688 Jingdong] API interface package series, collection of product details pages, can run at high concurrency

API is the development interface of the application program. When developing the program, we may not need to develop some functions from the beginning to the end. We can use the existing functional modules developed, and this functional module is called library (library) ). For example: to achieve data transmission security, this requires the use of encryption technology, which requires the use of encryption algorithms, and encryption algorithms, there are already kind people who have helped us develop an encryption algorithm library, you can directly call , no need to develop an algorithm

 Business scenario: As one of the largest B2C e-commerce platforms in the world, Taobao Tmall platform provides abundant commodity resources and attracts a large number of global buyers and sellers. In order to facilitate developers to access the Taobao Tmall platform, the Taobao Tmall platform provides a wealth of API interfaces, of which the historical price interface is a very important part. We have discussed the stable collection of Taobao (Tmall), JD.com, Alibaba, Pinduoduo and other platforms. The real-time product details historical price data interface of the entire site. Through this interface, developers can better understand the product situation, product details data detailed information query, and data parameters include : Product link, product list main image, price, title, sku, inventory, sales volume, store nickname, store level, product details SKU attribute, product video, product coupon, promotion information, detail attribute description, baby ID, area ID, The complete data solution on the page of the place of delivery, delivery to, courier fee, logistics fee, etc. helps buyers to purchase and analyze products more accurately.

This got me interested in technical challenges. At present, I have done a stress test myself. The QPS is high, the probability of a slider is extremely low, and the API is overall stable, which can meet product analysis, competitive product analysis, brand monitoring, product moving, product upload, mall construction, Taobao customers, erp product selection, The performance requirements of business scenarios such as store synchronization, CID store order return interface, etc., the following describes the interface encapsulation code tutorial:
