Question

我正在尝试使用jquery发送请求并从另一个网站获得响应。请求已发送，我已经收到200。但是我无法从服务器收到响应消息，我看到evretime是该错误：（我在woocomerce中使用wordpress。我的管理员在bluehost上）

Execution time while using member function remove: 121

Execution time while using generic algorithm remove: 125


Process finished with exit code 0

这是我的标题：

#include <list>
#include <algorithm>
#include <chrono>
#include <iostream>

using namespace std;

int main()
{
    srand(time(nullptr));
    list<int>my_list1;
//    list<int>my_list2;
    int x = 2000 * 2000;

    for (auto i = 0; i < x; ++i)
    {
        auto random = rand() % 10;
//        my_list1.push_back(random);  // avoid pushing to front and back to avoid cache misses.
        my_list1.push_front(random);
    }

    list<int>my_list2(my_list1);

    auto started1 = std::chrono::high_resolution_clock::now();
    my_list1.remove(5);
    auto done1 = std::chrono::high_resolution_clock::now();
    cout << "Execution time while using member function remove: " << chrono::duration_cast<chrono::milliseconds>(done1 - started1).count();

    cout << endl << endl;

    auto started2 = std::chrono::high_resolution_clock::now();
    my_list2.erase(remove(my_list2.begin(), my_list2.end(),5), my_list2.end());
    auto done2 = std::chrono::high_resolution_clock::now();
    cout << "Execution time while using generic algorithm erase: " << chrono::duration_cast<chrono::milliseconds>(done2 - started2).count();

    cout << endl << endl;
}

还有我的请求API函数

您不需要CORS。

您可以在自己的网站上调用代理脚本，然后使用cURL或Guzzle从PHP进行调用。这就是我一直这样做的方式。

jQuery：

$.get('/your/proxy/url.php', {any: "vars", go: "here"}, function(data){
    console.log(data);
});

php：

<?php 

$data = file_get_contents('the url you are calling from js here'); 
header('Content-Type: application/javascript'); // if $data is JSON
echo $data; 
exit;

在wordpress网站上无法在标头（php）中启用CORS
