Glaze Http Client - Get Request: No data in response_body #2413
Description
Discussed in #2410
Originally posted by floyd3000 March 30, 2026
For my application, I'm using Glaze for JSON and networking. Unfortunately, I'm not getting any data in the Glaze response_body for some target URLs. For testing, I'm using "http://example.com" as the target and the Glaze Basic Usage Example for HTTP Client Networking.
Tested with:
Glaze Version 7.2.1 and 7.2.2
Asio Version 1.36 and 1.38
Tested on OS:
FreeBSD 15.0 and macOS Tahoe 26.2 with g++ and clang++
Clang and G++ Version:
macOS: Apple clang version 17.0.0 (clang-1700.6.3.2)
FreeBSD: g++ 14.2.0
FreeBSD: clang version 19.1.7
Example Code:
#include <iostream>
#include <string>
#include "glaze/net/http_client.hpp"
int main() {
glz::http_client client;
auto response = client.get("http://example.com");
if (response) {
std::cout << "Status: " << response->status_code << std::endl;
std::cout << "Body: " << response->response_body << std::endl;
// Access response headers
for (const auto& [name, value] : response->response_headers) {
std::cout << name << ": " << value << std::endl;
}
} else {
std::cerr << "Error: " << response.error().message() << std::endl;
}
return 0;
}Compile:

What am I doing wrong? Does anyone have any ideas?
Thank you so much for any help.
