How to count the number of likes for a comment from group members (VK)?

Question

Social media

There are applications and services for checking “cheated” likes, but they work with posts or photos. What to do in this situation? I understand that this is possible using the VK API, but my level in this is slightly less than 0.

Answer 1

So here's my solution. Clumsy, but works.
1. vk.com/dev/execute Enter
the code:
var group_id = <group id>;
var users = [];
var count = API.groups.getMembers({group_id: group_id}).count;
var offset = 0;
while (offset < count && offset <= 23000) {
users = users + API.groups.getMembers({group_id: group_id, offset: offset, count: 1000}).users;
offset = offset + 1000;
}
return users;
We save the resulting array in txt, carefully replacing all commas with nothing through Ctrl + H, so that it would be easier to feed the future program.
2. vk.com/dev.php?method=likes.getList
Here we get an array of id of users who have rated the post and write it to a new txt.
3. My clumsy code of the program that outputs the common elements of these arrays to a new file.
#include #include #include <assert.h>
using namespace std;
int main()
{
//
int a[10000];
int i=0;
intj=0;
int s=0;
intb[200];
ifstream in;
outstream out;
in.open("input_1.txt");
while (!in.eof()) {
i++;
in>>a[i];
}
in.close();
i=0;
in.open("input_2.txt");
while (!in.eof()) {
i++;
in>>b[i];
}
in.close();
out.open("output_1.txt");
for (i=0;i<9380;++i)
{
for (j=0;j<171;++j)
{
if (a[i]==b[j])
{
out<<a[i ]<<", ";
cout<<j<<endl;
s++;
};
};
};
out<<endl<<"Total: „<<s;
out.close();
cin.get();
//
return 0;
}
Parameters a,b and loop conditions change depending on the conditions :)
I did everything right in the debugger, so everything changes right in the code.
Next, we clean output_1 from zeros that may have appeared there (so Total is not telling the truth), we leave the commas, because we will then feed it to VK ...
4. vk.com/dev/users.
We feed here the list of id received in the third paragraph. At the output, we get a list of id already with first and last names (if fields are left empty).
5. Well, we drive this list into txt and already through Ctrl + H we can bring it into a more or less adequate form.
Well, that's all. I'm sure someone can do much better, but this option coped with the task.

Answer 2

We look at the documentation: https://vk.com/dev/likes.getList
For example, we need to get the number of likes of Alexander Pershin's comment to the post https://vk.com/webfont?w=wall-45971686_240
In the "Like" button code we find
<span class="like_link fl_l" id="like_link-45971686_wall_reply243" style="opacity: 1;">Мне нравится</span>
The first number in id is owner_id, the second is item_id
Substituting the value in the constructor from the dev page, we get the request:
https://api.vkontakte.ru/method/likes.getList?type=comment&owner_id=-45971686&item_id=243
and we get in answer:
{"response":{"count":2,"users":[53901371,8324281]}}
