thanks
You can simple use the BatchFB api its very powerful and easy , you dont have to deal will all of these stuff and it use the fql for example to get all your friends
Later<ArrayNode> friendsArrayList = this.Batcher.query("SELECT uid FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1 = me())");
for (JsonNode friend : friendsArrayList.get()) {
.......
}
and its batched
I believe your question is how to execute a batch request using Facebook Graph API. For this you have to issue a POST request to
"https://graph.facebook.com"
and the post data to be sent should be
"batch=[{'method': 'GET', 'relative_url': 'me'}, {'method': 'GET', 'relative_url': 'me/friends?limit=50'}]&access_token=@accesstoken"
in your case [@accesstoken must be replaced with your access token value].
This request will return the details of the owner of the access token(normally the current logged in user) and a list of 50 facebook friends(contains id and name fields) of the user along with page headers(can be omitted).
I am not sure whether you meant java or Javascript. Please be specific on it.
I am a C# programmer basically. Will provide you a code to execute the above request in C# here.
WebRequest webRequest = WebRequest.Create("https://graph.facebook.com");
webRequest.Method = "POST";
webRequest.ContentType = "application/x-www-form-UrlEncoded";
byte[] buffer = Encoding.UTF8.GetBytes("batch=[{'method': 'GET', 'relative_url': 'me'}, {'method': 'GET', 'relative_url': 'me/friends?limit=50'}]&access_token=@ACCESSTOKEN");
webRequest.ContentLength = buffer.Length;
using (Stream stream = webRequest.GetRequestStream())
{
stream.Write(buffer, 0, buffer.Length);
using (WebResponse webResponse = webRequest.GetResponse())
{
if (webResponse != null)
{
using (StreamReader streamReader = new StreamReader(webResponse.GetResponseStream(), Encoding.UTF8))
{
string data = streamReader.ReadToEnd();
}
}
}
}
Here the variable data will contain the result.
Salah, here is the example i use as reference, i am sorry though i do not remember where i found.
FB.api("/", "POST", {
access_token:"MY_APPLICATION_ACCESS_TOKEN",
batch:[
{
"method":"GET",
"name":"get-photos",
"omit_response_on_success": true,
"relative_url":"MY_ALBUM_ID/photos"
},
{
"method": "GET",
"depends_on":"get-photos",
"relative_url":"{result=get-photos:$.data[0].id}/likes"
}
]
}, function(response) {
if (!response || response.error) {
console.log(response.error_description);
} else {
/* Iterate through each Response */
for(var i=0,l=response.length; i<l; i++) {
/* If we have set 'omit_response_on_success' to true in the Request, the Response value will be null, so continue to the next iteration */
if(response[i] === null) continue;
/* Else we are expecting a Response Body Object in JSON, so decode this */
var responseBody = JSON.parse(response[i].body);
/* If the Response Body includes an Error Object, handle the Error */
if(responseBody.error) {
// do something useful here
console.log(responseBody.error.message);
}
/* Else handle the data Object */
else {
// do something useful here
console.log(responseBody.data);
}
}
}
});
