(Go) Read a Single Facebook PostDemonstrates how to read the contents of a single Facebook post. A post is an individual entry in a profile's feed. The profile could be a user, page, app, or group.
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // This example assumes a previously obtained an access token oauth2 := chilkat.NewOAuth2() oauth2.SetAccessToken("FACEBOOK-ACCESS-TOKEN") rest := chilkat.NewRest() // Connect to Facebook... success := rest.Connect("graph.facebook.com",443,true,true) if success != true { fmt.Println(rest.LastErrorText()) oauth2.DisposeOAuth2() rest.DisposeRest() return } // Provide the authentication credentials (i.e. the access key) rest.SetAuthOAuth2(oauth2) // This example assumes a post id was already retrieved. // For example, it could've been retrieved by reading the user's feed: // See Parsing the Facebook User Feed for code showing how to parse the JSON feed content. postId := "10224048320139890_10210156138515282" sbPath := chilkat.NewStringBuilder() sbPath.Append("/v2.7/") sbPath.Append(postId) // Select the fields we want. // This example will select almost all the possible fields. // See https://developers.facebook.com/docs/graph-api/reference/post/ rest.AddQueryParam("fields","id,message,created_time,caption,description,from,link,name,object_id,picture,place,privacy,properties,shares,source,status_type,story,targeting,to,type,updated_time,with_tags") responseJson := rest.FullRequestNoBody("GET",*sbPath.GetAsString()) if rest.LastMethodSuccess() != true { fmt.Println(rest.LastErrorText()) oauth2.DisposeOAuth2() rest.DisposeRest() sbPath.DisposeStringBuilder() return } json := chilkat.NewJsonObject() json.SetEmitCompact(false) json.Load(*responseJson) // Show the JSON in human-readable format. fmt.Println(*json.Emit()) // A sample JSON response is shown here. // { // "id": "12345678901234567_12345678900000004", // "message": "Ignore my posts -- I'm doing some testing for Facebook related programming...", // "created_time": "2016-09-29T20:46:18+0000", // "from": { // "name": "John Doe", // "id": "12345678901234567" // }, // "link": "https:\/\/www.facebook.com\/photo.php?fbid=10210199026247451&set=a.1237223526054.2038240.1094202869&type=3", // "object_id": "10210139026347451", // "picture": "https:\/\/scontent.xx.fbcdn.net\/v\/t1.0-9\/14462791_10210199026647451_7830642117574407060_n.jpg?oh=a7f9ed10ce9cd81a82adeb541c60e2e2&oe=58ABB195", // "privacy": { // "allow": "", // "deny": "", // "description": "Public", // "friends": "", // "value": "EVERYONE" // }, // "status_type": "added_photos", // "type": "photo", // "updated_time": "2016-09-29T20:46:18+0000" // } // This is the code to parse some fields in the JSON response. fmt.Println("type: ", *json.StringOf("type")) fmt.Println("message: ", *json.StringOf("message")) fmt.Println("id: ", *json.StringOf("id")) fmt.Println("link: ", *json.StringOf("link")) fmt.Println("privacy descripton: ", *json.StringOf("privacy.description")) dtime := chilkat.NewCkDateTime() bLocalTime := true dtime.SetFromTimestamp(*json.StringOf("created_time")) dt := dtime.GetDtObj(bLocalTime) fmt.Println(dt.Month(), "/", dt.Day(), "/", dt.Year(), " ", dt.Hour(), ":", dt.Minute()) dt.DisposeDtObj() oauth2.DisposeOAuth2() rest.DisposeRest() sbPath.DisposeStringBuilder() json.DisposeJsonObject() dtime.DisposeCkDateTime() |
