Cursor-based pagination is the most efficient method of paging and should always be used where possible - a cursor refers to a random string of characters which mark a specific item in a list of data. Unless this item is deleted, the cursor will always point to the same part of the list, but it will be invalidated if an item is removed. Therefore, your app shouldn't store any older cursors or assume that they will still be valid.
When reading an edge that supports cursor pagination, you will see the following JSON response:
{
"data": [
... Endpoint data is here
],
"paging": {
"cursors": {
"after": "MTAxNTExOTQ1MjAwNzI5NDE=",
"before": "NDMyNzQyODI3OTQw"
},
"previous": "https://graph.facebook.com/me/albums?limit=25&before=NDMyNzQyODI3OTQw"
"next": "https://graph.facebook.com/me/albums?limit=25&after=MTAxNTExOTQ1MjAwNzI5NDE="
}
}
我正在使用这种格式进行 api 调用,如何循环遍历所有页面
/* make the API call */
new GraphRequest(
session,
"/{user-id}/statuses",
null,
HttpMethod.GET,
new GraphRequest.Callback() {
public void onCompleted(GraphResponse response) {
/* handle the result */
}
}
).executeAsync();

我想出了一个使用光标分页遍历 facebook graph api 页面的好方法
final String[] afterString = {""}; // will contain the next page cursor
final Boolean[] noData = {false}; // stop when there is no after cursor
do {
Bundle params = new Bundle();
params.putString("after", afterString[0]);
new GraphRequest(
accessToken,
personId + "/likes",
params,
HttpMethod.GET,
new GraphRequest.Callback() {
@Override
public void onCompleted(GraphResponse graphResponse) {
JSONObject jsonObject = graphResponse.getJSONObject();
try {
JSONArray jsonArray = jsonObject.getJSONArray("data");
// your code
if(!jsonObject.isNull("paging")) {
JSONObject paging = jsonObject.getJSONObject("paging");
JSONObject cursors = paging.getJSONObject("cursors");
if (!cursors.isNull("after"))
afterString[0] = cursors.getString("after");
else
noData[0] = true;
}
else
noData[0] = true;
} catch (JSONException e) {
e.printStackTrace();
}
}
}
).executeAndWait();
}
while(!noData[0] == true);
