我试图将多个API请求中的数据拉入单个数组（用于显示），而API限制了我一次可以拉取的记录数量。不幸的是，我没有足够的客户端购买来测试我的递归，所以我希望有人能看看我的测试类，看看它是否应该工作。
这是我迄今为止所拥有的。request方法采用参数$service和$page，然后根据"recsindb"的数量增加$page。例如，如果recsindb=50，那么$page应该增加5倍，每组中有10条记录。
这是我写的代码：
$check = new testClass;
// API services to loop through
$services = array(
"dns" => "domains/search.json",
"webservices" => "webservices/search.json",
"singledomainhostinglinuxus" => "singledomainhosting/linux/us/search.json",
"singledomainhostinglinuxuk" => "singledomainhosting/linux/uk/search.json"
);
// foreach service, assign a key to identify the data in the display
foreach ($services as $key => $value) {
$data[$key] = $check->getData($value);
}
// Let's see what we got
echo "<pre>" . print_r($data, TRUE) . "</pre>";
class testClass {
function getData($api) {
$fullurl = "https://myapipath/" . $api . "?" . $this->buildstring();
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_URL, $fullurl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
curl_close($ch);
return json_decode($data, true);
}
// Array key => value pairs
private $parts = array();
public function add($key, $value) {
$this->parts[] = array(
'key' => $key,
'value' => $value
);
}
// Build the query string
public function buildstring($separator = '&', $equals = '=') {
$queryString = array();
foreach ($this->parts as $part) {
$queryString[] = urlencode($part['key']) . $equals . urlencode($part['value']);
}
return implode($separator, $queryString);
}
// recursive function
public function request($service, $page) {
$count = 10; // 10 records is the minimum allowed to request
$this->add(array('no-of-records', $count));
$this->add(array('page-no', $page));
$data = $this->getData(array($service, TRUE));
if ($data[0]['recsindb'] > $page * $count) {
$data = $this->request($service, $page + 1);
}
return $data;
}
}
我最终创建了一个数据库和API服务来模拟流程。到目前为止，这个带有array_merge的请求方法似乎就是我想要的：
// recursive function
public function request($service, $page) {
$count = 10;
$this->add('no-of-records', $count);
$this->add('page-no', $page);
$data = $this->getData($service);
if ($data['recsindb'] > $page * $count) {
$data = array_merge($data, $this->request($service, $page + 1));
}
return $data;
}
