Question

我有一个curl函数，可以在小行星上请求数据并获得结果。目前我只是在结果的日期参数中进行硬编码，我希望用户能够输入他们选择的日期并得到结果我怎么能添加这个，我是新手使用Curl并继续撞墙，到目前为止的代码在下面，

<?php
session_start();
// Method: POST, PUT, GET etc
// Data: array("param" => "value") ==> index.php?param=value

function CallAPI($method, $url, $data = false)
{
    $curl = curl_init();

    switch ($method) {
        case "POST":
            curl_setopt($curl, CURLOPT_POST, 1);

            if ($data)
                curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
            break;
        case "PUT":
            curl_setopt($curl, CURLOPT_PUT, 1);
            break;
        default:
            if ($data)
                $url = sprintf("%s?%s", $url, http_build_query($data));
    }
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
    $result = curl_exec($curl);
    if ($result === FALSE) {
        die(curl_error($curl));
    }
    curl_close($curl);
    return $result;
}
$params = array(
    'start_date' => '01/03/2016',
    'end_date' => '02/03/2016',
    'api_key' => 'demo key'
);
$data   = json_decode(callAPI('GET', 'https://api.nasa.gov/neo/rest/v1/feed', $params));

//var_dump($data);

echo "<h1>Near-Earth Object (NEO) Report between " . $params['start_date'] . " and " . $params['end_date'] . "</h1>";

foreach ($data->near_earth_objects as $date => $count) {
    echo "<p>" . sizeof($count) . " objects detected on $date</p>";

    echo "<ol>";
    foreach ($data->near_earth_objects->$date as $near_earth_object) {
        echo "<li>" . $near_earth_object->name . " <a href='" . $near_earth_object->nasa_jpl_url . "'>" . $near_earth_object->nasa_jpl_url . "</a><br>";
        echo "Estimated Diameter: " . $near_earth_object->estimated_diameter->meters->estimated_diameter_min . "-" . $near_earth_object->estimated_diameter->meters->estimated_diameter_max . " metres<br>";

        echo "<ul>";
        foreach ($near_earth_object->close_approach_data as $close_approach) {
            echo "<li>Close approach on " . $close_approach->close_approach_date . " velocity " . $close_approach->relative_velocity->kilometers_per_hour . " km/h " . "missing " . $close_approach->orbiting_body . " by " . $close_approach->miss_distance->kilometers . " km</li> ";
        }
        echo "</ul></li>";
    }
    echo "</ol>";
}
?>

你很亲密。我稍微修改了你的代码。您的日期格式也不正确。当API调用public void addRow (string[] values) { // Validate public methods arguments if (null == values) throw new ArgumentNullException("values"); // Make the query parametrized: it's faster and not prone to SQL injection // Do not append String in a loop; use Join instead string sql = string.Format("INSERT INTO {0} VALUES ({1})", tableName, string.Join(", ", values.Select((item, index) => "@param_" + index.ToString())); // wrap IDisposable into using // let createConnection() return the connection created using (var con = createConnection()) { con.Open(); // wrap IDisposable into using using (var cmd = new SqlCommand(sql, con)) { // Parametrized query: parameters assigning for (int index = 0; index < values.Length; ++index) cmd.Parameters.AddWithValue("@param_" + index.ToString(), values[i]); // Finally query executing cmd.ExecuteNonQuery(); } } } #include <tuple> template <typename Class, typename T> struct Property { constexpr Property(T Class::* const member) : m_member{ member } {} T Class::* const m_member; }; template <class T, class V> constexpr Property<T, V> get_age_property() { return Property<T, V>(&T::age); } class User { public: int age; constexpr static std::tuple<Property<User, int>> properties = std::make_tuple( get_age_property<User, int>() ); }; int main() { }时，您提供的格式为mm/dd/yyyy（请注意年份在前面，您需要连字符而不是斜线）。

我在开始日期和结束日期使用了GET值（请注意，API仅在开始日期和结束日期之间允许format）。因此，您可以通过将yyyy-mm-dd添加到用于访问此代码的URL的末尾来更改日期（它也可以实现为GET方法表单）：

?start=2015-05-01&end=2015-05-05

可以用strtotime理解的任何格式输入日期。如果日期无效，则默认为今天的日期。如果API抛出错误（比如日期范围大于7天），它只会抛出错误。您可能想要添加一些错误检测。

将Curl参数作为参数传递
