(Excel) Facebook Upload Photo from Local FileUploads a new photo with a caption from a local file.
' This example assumes Chilkat HTTP to have been previously unlocked. ' See Global Unlock Sample for sample code. Dim http As Chilkat.Http Set http = Chilkat.NewHttp Dim req As Chilkat.HttpRequest Set req = Chilkat.NewHttpRequest req.HttpVerb = "POST" req.ContentType = "multipart/form-data" req.Path = "/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 <> True) Then Debug.Print req.LastErrorText Exit Sub End If ' Upload the image file.. Set resp = http.SynchronousRequest("graph.facebook.com",443,True,req) If (http.LastMethodSuccess <> True) Then Debug.Print http.LastErrorText Exit Sub End If ' Examine the response body: responseJson = resp.BodyStr Debug.Print responseJson ' The response contains JSON, such as this: ' {"id":"10210224963435862","post_id":"10224048320139890_10210224963435862"} |
