(C++) curl with Path Variables and Query Param VariablesSee more CURL ExamplesThis example demonstrates using variables located in the path and query params with the {{variable_name}} syntax.Note: This example requires Chilkat v11.5.0 or greater.
#include <CkHttpCurl.h> #include <CkJsonObject.h> void ChilkatSample(void) { bool success = false; // Variables can occur in the path and query params. // Variable names are enclosed between {{ and }} // curl -X GET https://httpbin.org/{{verb}}?id={id_value}} const char *targetCurl = "curl -X GET https://httpbin.org/{{verb}}?id={{id_value}}"; CkHttpCurl httpCurl; // Provide values for variables. // In this example, "verb" is a path variable, and "id_value" is a query param variable. httpCurl.SetVar("verb","get"); httpCurl.SetVar("id_value","123"); // Run the curl command. success = httpCurl.DoYourThing(targetCurl); if (success == false) { std::cout << httpCurl.lastErrorText() << "\r\n"; return; } CkJsonObject responseJson; responseJson.put_EmitCompact(false); int statusCode = httpCurl.get_StatusCode(); std::cout << "response status code: " << statusCode << "\r\n"; httpCurl.GetResponseJson(responseJson); std::cout << responseJson.emit() << "\r\n"; // Output: // response status code: 200 // { // "args": { // "id": "123" // }, // "headers": { // "Host": "httpbin.org", // "X-Amzn-Trace-Id": "Root=1-69e92914-5d4136d240f2f7fe1056f126" // }, // "origin": "222.222.222.222", // "url": "https://httpbin.org/get?id=123" // } } |
