API technology sharing post: How to obtain real-time data from e-commerce platforms?

The product data, order data, buyer data, and seller data of each e-commerce platform are very large, and the update speed is also very fast. Especially during Double Eleven, 618 and other major promotions, how to capture real-time data from various platforms in real time, monitor e-commerce operations, and do accurate data analysis? This is a big problem faced by many e-commerce operation software.

The following open API interfaces capture real-time data, support high concurrent requests, and obtain the API call address.

Some code samples

#include<iostream>
#include<string>
#include<curl/curl.h>

using namespace std;

static size_t Data(void *ptr, size_t size, size_t nmemb, string *stream)
{
    std::size_t realSize = size *nmemb;
    auto *realPtr = reinterpret_cast<char *>(ptr);

    for (std::size_t i=0;i<realSize;++i) {
        *(stream) += *(realPtr + i);
    }

    return realSize;
}

int main(){

     CURL *curl;
     CURLcode result;
     string readBuffer;
     curl = curl_easy_init();

     if(curl) {

         curl_easy_setopt(curl, CURLOPT_URL, "https://服务器地址/taobao/item_get/?key=<您自己的apiKey>&secret=<您自己的apiSecret>&num_iid=652874751412&is_promotion=1");
         curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
         curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, Data);
         curl_easy_setopt(curl, CURLOPT_WRITEDATA, &readBuffer);

         result = curl_easy_perform(curl);

         if(result == CURLE_OK) {
             cout<<readBuffer<<endl;
         }else{
             cerr<<"curl_easy error:"<<curl_easy_strerror(result)<<endl;
         }

         curl_easy_cleanup(curl);
     }
     return 0;
}
