when visiting by Chrome, it's ok, the response data is a tiled image.
I tested using Cinatra, however, the response value is 400.
so can someone teach me how to solve the problem :-)
you need add definition: CINATRA_ENABLE_SSL, set it as ON. and make sure you have installed openssl.
Yes, I defined the CINATRA_ENABLE_SSL macro and linked it to libssl 1.0.2. I was able to compile and link successfully. However, when I tried to set a proxy, the v2ray software crashed. So instead, I tried setting up a https uri that doesn't require a proxy, but it didn't work correctly. the response value is 400.
test code :
#include "cinatra.hpp"
void testhttpstile_cinatra()
{
#ifdef CINATRA_ENABLE_SSL
cinatra::coro_http_client client2{};
client2.init_ssl();
auto result = client2.get("https://baidu.com");
assert(result.status == 200);
client2.set_proxy("127.0.0.1", "10809");
auto result1 = client2.get("https://mt.google.com/vt/lyrs=t,r&hl=x-local&src=app&apistyle=s.t%3A0%7Cs.e%3Al%7Cp.v%3Aoff&x=1&y=3&z=2");
assert(result1.status == 200);
#endif
}
call client2.get("https://baidu.com")
result.resp_body is :
<html>
<head><title>302 Found</title></head>
<body bgcolor="white">
<center><h1>302 Found</h1></center>
<hr><center>bfe/1.0.8.18</center>
</body>
</html>
call client2.get("https://mt.google.com/....
result.resp_body is:
<html>
<head><title>405 Not Allowed</title></head>
<body bgcolor="white">
<center><h1>405 Not Allowed</h1></center>
<hr><center>bfe/1.0.8.18</center>
</body
use a new client to call google, one host one client.
no need to call init_ssl
after use seperate client, and comment init_ssl call, the result status is 302 and 404.
I add CINATRA_ENABLE_SSL, but while compiling, cinatra didn't ask to include ssl head and link to ssl library?
maybe my path has contain ssl sdk?
I catch message from v2rayN，the client.get function call cause message like

the correct should like
accepted //mt.google.com:443
I don't know why, how to solve
if you call "https://baidu.com/" get 302, it's ok.
I think call google is similar.

if you don't use proxy, visit goole directly i think it's ok, you can have a try.
Use http, maybe your proxy software does not support https.
My vpn doesn't support it.
Like this:
According to your v2ray message, it only supports http proxy.Change to use http and it will be successful.
coro_http_client client3{};
client3.set_proxy("192.168.102.1", "7890");
auto result1 = client3.get("http://mt.google.com/vt/lyrs=t,r&hl=x-local&src=app&apistyle=s.t%3A0%7Cs.e%3Al%7Cp.v%3Aoff&x=1&y=3&z=2");
std::cout << result1.status << std::endl;status is 200.
Hi helintongh， thanks for your reply.
you get the correct status 200, so ...
I don't know which part is faulty, maybe the program linked to the wrong SSL library or something else.
but I test another library called httplib, get the same URI, it's OK， I got 200 and can save the tile image.
so I think cinatra is good, the proxy is good, it must something I didn't put correctly.
the httplib test code is follow:
#define CPPHTTPLIB_OPENSSL_SUPPORT
#include "httplib.h"
void testhttpstile_httplib(std::string uri = "https://mt.google.com")
{
httplib::Client cli(uri);
cli.set_proxy("127.0.0.1", 10809);
auto res = cli.Get("/vt/lyrs=t,r&hl=x-local&src=app&apistyle=s.t%3A0%7Cs.e%3Al%7Cp.v%3Aoff&x=1&y=3&z=2");
res->status;
res->body;
}
and I reported a typo, in coro_http_client.hpp, init_config function,
if (!conf.proxy_host.empty()) {
I think should call set_proxy, but the current code calls set_proxy_basic_auth.
Is this a typo?

No, I need to solve https, for many uri don't have http version.

It is currently confirmed that cinatra does not support https proxy for the time being.I will complete this feature tomorrow.The https proxy must first establish a connection with the server through http and then forward it.
and I reported a typo, in coro_http_client.hpp, init_config function, if (!conf.proxy_host.empty()) { I think should call set_proxy, but the current code calls set_proxy_basic_auth.

@qicosmos Is it?
set_proxy is better.
in pr solve this question.
example code is as following:
#include <iostream>
#include "../include/cinatra.hpp"
#include "cinatra/ylt/metric/gauge.hpp"
#include "cinatra/ylt/metric/histogram.hpp"
#include "cinatra/ylt/metric/summary.hpp"
using namespace cinatra;
using namespace std::chrono_literals;
int main() {
// use_metric();
coro_http_client client{};
client.set_proxy("192.168.16.1", "7890");
// auto ret = client.async_request(url, http_method::GET, req_context<>{}, {},
// std::span<char>{str.data(), str.size()});
// auto result = async_simple::coro::syncAwait(ret);
std::unordered_map<std::string, std::string> headers = {
{"User-Agent", "cpp-httplib/0.15.3"},
{"Connection", "close"}
};
std::string uri = "https://mt.google.com/vt/lyrs=t,r&hl=x-local&src=app&apistyle=s.t%3A0%7Cs.e%3Al%7Cp.v%3Aoff&x=1&y=3&z=2";
auto result1 = async_simple::coro::syncAwait(client.async_request_upgrade(uri, http_method::GET, req_context<>{}, headers));
std::cout << result1.status << std::endl;
return 0;
}in pr solve this question.
example code is as following:
#include <iostream> #include "../include/cinatra.hpp" #include "cinatra/ylt/metric/gauge.hpp" #include "cinatra/ylt/metric/histogram.hpp" #include "cinatra/ylt/metric/summary.hpp" using namespace cinatra; using namespace std::chrono_literals; int main() { // use_metric(); coro_http_client client{}; client.set_proxy("192.168.16.1", "7890"); // auto ret = client.async_request(url, http_method::GET, req_context<>{}, {}, // std::span<char>{str.data(), str.size()}); // auto result = async_simple::coro::syncAwait(ret); std::unordered_map<std::string, std::string> headers = { {"User-Agent", "cpp-httplib/0.15.3"}, {"Connection", "close"} }; std::string uri = "https://mt.google.com/vt/lyrs=t,r&hl=x-local&src=app&apistyle=s.t%3A0%7Cs.e%3Al%7Cp.v%3Aoff&x=1&y=3&z=2"; auto result1 = async_simple::coro::syncAwait(client.async_request_upgrade(uri, http_method::GET, req_context<>{}, headers)); std::cout << result1.status << std::endl; return 0; }
I pulled the last code but still did not support HTTPS, there is no async_request_upgrade method in the coro_http_client class.
