[Help] How do I send "Azure" style request to an API?

[Stavros Grigoriou]

Good evening,

First of all thank you very much for building this project, it has been a huge help for me so far. I'm using it constantly to get responses from APIs, but I'm currently stuck for hours in the same point so I decided to make this post in seek for an answer.

I'm trying to send an API Search Request on Azure that should contain this information: https://i.imgur.com/wMmAODW.png

I'm having problem approaching this using this library, can anybody possibly give me a bit of help on this?

Thanks is advance :)

Hi @unix121
I am glad you found curlcpp useful! I think that you should perform a GET request including an header named "Ocp-Apim-Subscription-Key" with the relative value. Here's an example of how I think you should do, based on that screenshot:

#include "curl_easy.h"
#include "curl_form.h"
#include "curl_header.h"

using curl::curl_header;
using curl::curl_easy;
using curl::curl_easy_exception;
using curl::curlcpp_traceback;

/*
 * This example shows how to add custom headers to a simple
 * curl request.
 */

int main() {
    // Let's create an object which will contain a list of headers.
    curl_header header;
    // Easy object to handle the connection.
    curl_easy easy;

    // Add custom headers, in this case, your key.
    header.add("Ocp-Apim-Subscription-Key:value_of_sub_key");

    // Add the headers to the easy object.
    easy.add<CURLOPT_HTTPHEADER>(header.get());
    
    easy.add<CURLOPT_URL>("https://api.cognitive.microsoft.com/bing/v5.0/search?q=bill%20gates");
    // You can disable verbosity using 0L
    easy.add<CURLOPT_VERBOSE>(1L);
    try {
        // Request execution
        easy.perform();
    } catch (curl_easy_exception error) {
        // If you want to get the entire error stack we can do:
        curlcpp_traceback errors = error.get_traceback();
        // Otherwise we could print the stack like this:
        error.print_traceback();
    }
    return 0;
}

Obviously, you have to change "value_of_sub_key" with the one you have. Let me know.

This is exactly what I wanted, it seems like I was constructing the header in a wrong way but you provided the best answer. Thank you very much kind sir!
