FCM推送通知未使用php

Question

我通过FCM控制台收到通知，但使用php脚本未收到通知， 但获得了成功的反应

#include <iostream>
#include <vector>
#include <string_view>

class LCSMemoizer
{
    std::vector<std::vector<int>> memory;
    std::string_view s1;
    std::string_view s2;

public:
    LCSMemoizer(std::string_view s1, std::string_view s2)
    : memory(s1.size(), std::vector<int>(s2.size(), -1)), s1(s1), s2(s2)
    {
    }

    int run(unsigned int i1, unsigned int i2)
    {
        if(i1 == s1.size() || i2 == s2.size())
        {
            return 0;
        }
        if(memory[i1][i2] != -1)
        {
            return memory[i1][i2];
        }
        int sub = 0;
        if(s1[i1] == s2[i2])
        {
            sub = run(i1+1, i2+1);
            sub += 1;
        }
        else
        {
            sub = std::max(run(i1, i2+1), run(i1+1, i2));
        }
        memory[i1][i2] = sub;
        return sub;
    }
};

int lcs(std::string_view s1, std::string_view s2)
{
    LCSMemoizer m(s1, s2);

    return m.run(0, 0);
}

int main()
{
    std::cout << lcs("bd", "abcd");
}

这是我的代码：

{
    "multicast_id":5910735205973551931,
    "success":1,
    "failure":0,
    "canonical_ids":0,
    "results":[
        {"message_id":"0:1546112175917189%8283ae068283ae06"}
    ]
