    curl "github.com/andelf/go-curl"
)

func main() {
    easy := curl.EasyInit()
    defer easy.Cleanup()

    easy.Setopt(curl.OPT_URL, "http://www.baidu.com/")

    // make a callback function
    fooTest := func (buf []byte, userdata interface{}) bool {
        println("DEBUG: size=>", len(buf))
        println("DEBUG: content=>", string(buf))
        return true
    }

    easy.Setopt(curl.OPT_WRITEFUNCTION, fooTest)

    if err := easy.Perform(); err != nil {

    [WIP] Fix concurrent map read and map write

    Fixes issue with concurrent map read and map write related to context_map.

    Maps are not safe for concurrent use: it's not defined what happens when you read and write to them simultaneously. - http://blog.golang.org/go-maps-in-action

    Wrapped context map inside a struct with sync.RWMutex Added a test case to verify that it is working, test with go test -race.

    Error on using go get to install your packages in go1

    Hello andelf,

    I just wanted to try your package on my machine (Ubuntu 11.10, 64bit / go 1), but on issuing the "go get" command from your readme, I get the following error-messages from go :

    go get -u github.com/andelf/go-curl/curl

    github.com/andelf/go-curl/curl

  • Return HTTP status

    Return HTTP status

    Hello, I'm relatively new to Go and don't know on how to approach on debugging Go libraries.

    My question is how do we log the HTTP Status (200, 400, 502) when using this library? The doc only shows how to get the response.

    Thanks for the help!

  • Getting SSL certificate expiry date

    Getting SSL certificate expiry date

    Hi, I am looking to retrieve SSL certificate expiry date information for a site. I see there is a INFO_CERTINFO argument to Easy GetInfo() method to obtain this information. The call is supposed to return a slist of certificates in the chain (I presume). However, the test code crashes when this parameter to used.

    Is there a way around this or some example code to try out? Or, is there any other way to get the same information using a different API call? if err := easy.Perform(); err != nil { fmt.Printf("ERROR: %v\n", err) } else { x, err := easy.Getinfo(curl.INFO_CERTINFO) if err != nil { } fmt.Printf("certinfo:%f", x) }

    goroutine 1 [running]: github.com/andelf/go-curl.(*CURL).Getinfo.func5(0x40743c, 0x0, 0x0) /DIR/pkg/mod/github.com/andelf/[email protected]/easy.go:409 +0x5b github.com/andelf/go-curl.(*CURL).Getinfo(0xc00010a000, 0x400022) /DIR/pkg/mod/github.com/andelf/[email protected]/easy.go:409 +0xe6 main.main() /DIR/gotest/hello/main.go:27 +0xff exit status 2

    Thanks and appreciate all the hard work that went into this work!

  • Get cURL error code

    Get cURL error code

    I haven't found a way to get cURL error code so far. When using EasyInit, it's returning error message string like curl: Couldn't resolve host name.

    func main() {
        easy := curl.EasyInit()
	defer easy.Cleanup()

	easy.Setopt(curl.OPT_URL, "http://zzzzzzzz---.com")

	if err := easy.Perform(); err != nil {
		fmt.Println(err, err.Error())
	}
}

    But, how to get the cURL error code like the libcurl equivalent returns.

    int main(int argc, char *argv[]) {
    CURL *easyhandle = curl_easy_init();
    curl_easy_setopt(easyhandle, CURLOPT_URL, "http://zzzzzzzz---.com");
    int errorCode = curl_easy_perform(easyhandle);
    printf("Error Code: %d %d\n", errorCode, errorCode == CURLE_COULDNT_RESOLVE_HOST);
    return 0;
}
  • HTTP2 support?

    HTTP2 support?

    Curl has http2 support since some time ago https://curl.se/docs/http2.html. In fact, it is enabled by default when https is used.

    Is it planned to get this options supported in the project? If not, I would like to understand what it is needed to enable it.

    Supporting these new options involves executing the pre-processor programs like: https://github.com/andelf/go-curl/pull/51 or is it needed an extra effort to enable it?

    Of course, I suppose that supporting some of the new HTTP2 features (streaming, bidirectional, etc.) will require an extra effort, but maybe a "light" version of http2 support would take advantage of most features in HTTP2 (speed, compression, security, etc.).
