Facebook Upload Photo from Local File

See more Facebook Examples

Uploads a new photo with a caption from a local file. Go

    success := false

    //  This example assumes Chilkat HTTP to have been previously unlocked.
    //  See Global Unlock Sample for sample code.

    http := chilkat.NewHttp()

    req := chilkat.NewHttpRequest()
    req.SetHttpVerb("POST")
    req.SetContentType("multipart/form-data")
    req.SetPath("/v2.7/me/photos")

    //  Use the previously obtained access token.
    //  Note: The publish_actions scope is required to upload a photo.
    req.AddHeader("Authorization","Bearer FACEBOOK-ACCESS-TOKEN")

    //  Send an "Expect: 100-continue" header in the request.
    //  This causes the HTTP server to end a 100-continue response
    //  immediately after receiving the HTTP header.  The client
    //  (Chilkat) will receive this intermediate response, and if
    //  it's not an error response, it knows that the HTTP server will
    //  accept the data that is forthcoming.
    //  The alternative is to get an error response after trying to upload
    //  the entire contents of the files.
    req.AddHeader("Expect","100-continue")

    //  Set a photo caption.
    req.AddParam("caption","Here are some penguins!")

    //  Additional parameters can be added to the request by 
    //  calling AddParam once per parameter.  
    //  See https://developers.facebook.com/docs/graph-api/reference/user/photos
    //  for more information about other optional parameters.

    //  Indicate the local file to be uploaded.
    success = req.AddFileForUpload("source","qa_data/jpg/penguins2.jpg")
    if success == false {
        fmt.Println(req.LastErrorText())
        http.DisposeHttp()
        req.DisposeHttpRequest()
        return
    }

    //  Upload the image file..
    resp := chilkat.NewHttpResponse()
    success = http.HttpSReq("graph.facebook.com",443,true,req,resp)
    if success == false {

        http.DisposeHttp()
        req.DisposeHttpRequest()

        return

    //  Examine the response body:
    responseJson := resp.BodyStr()
    fmt.Println(responseJson)

    //  The response contains JSON, such as this:
    //  {"id":"10210224963435862","post_id":"10224048320139890_10210224963435862"}
