我的PHP在我的PHP Fiddle中工作,但是当我将其完全复制到Sublime 2时,将其保存为.php文档,并将其上传到我的服务器here on my website。我认为在JSON中存在的问题是,它不是正确解码信息而且始终是“无效ID”,但是如果你在小提琴中运行它总是给出至少3-4个正确的名字。但在Chrome,Firefox或Safari等浏览器中,我从未获得任何名称。为什么会这样?
<?php
function gen_pix($min, $max, $quantity) {
$numbers = range($min, $max);
shuffle($numbers);
$x_arr = array_slice($numbers, 0, $quantity);
foreach ($x_arr as $key => $value) {
$username = "https://graph.facebook.com/" . $value . "/";
$json = json_decode(file_get_contents($username), true);
if (!isset($json['name'])) {
echo "Invalid ID<br />";
}
else {
echo $json["name"]. '<br />';
}
}
}
$x = 337800042;
$y = 337800382;
$z = 50;
gen_pix($x,$y,$z);
?>
更新:已启用错误报告。
Warning: file_get_contents(): https:// wrapper is disabled in the server configuration by allow_url_fopen=0 in /hermes/bosoraweb186/b1303/ipg.joshiefishbeincom/fi/namebook4.php on line 11 Warning: file_get_contents(https://graph.facebook.com/337800127/): failed to open stream: no suitable wrapper could be found in /hermes/bosoraweb186/b1303/ipg.joshiefishbeincom/fi/namebook4.php on line 11
更新2:现在使用cURL
这是我的新代码:
<?php
ini_set("display_errors",1);
error_reporting(E_ALL);
function gen_pix($min, $max, $quantity) {
$numbers = range($min, $max);
shuffle($numbers);
$x_arr = array_slice($numbers, 0, $quantity);
foreach ($x_arr as $key => $value) {
$username = "https://graph.facebook.com/" . $value . "/";
if (!function_exists("curl_init")){
die('Sorry cURL is not installed!');
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $username);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 60); // 60 seconds timeout
$json = curl_exec($ch);
curl_close($ch);
if (!isset($json['name'])) {
print("error");
}
else {
print($json["name"]). '<br />';
}
}
}
$x = 337800042;
$y = 337800382;
$z = 10;
gen_pix($x,$y,$z);
?>
现在它给了我每行“H”。所以我将else
切换为print_r($json);
以查看数组的外观,这就是我得到的内容:
HTTP/1.1 200 OK Access-Control-Allow-Origin: * Cache-Control: private, no-cache, no-store, must-revalidate Content-Type: application/json; charset=UTF-8 ETag: "f07656bdb736f1a09e1aa2bb16ecce2b3b1f483e" Expires: Sat, 01 Jan 2000 00:00:00 GMT Pragma: no-cache X-FB-Rev: 1135358 X-FB-Debug: Ha05GqDUPxzl4bA3x9xreOZCveNsf8QiOGExgPU9p6c= Date: Tue, 25 Feb 2014 05:12:49 GMT Connection: keep-alive Content-Length: 148 {"id":"337800051","name":"Irem Muftuoglu","first_name":"Irem","last_name":"Muftuoglu","gender":"female","locale":"nb_NO","username":"iremmuftuoglu"}
答案 0 :(得分:1)
我对Graph API
太熟悉了,但我得到了这个:
从小提琴 和我的本地服务器的.php 调用此内容,我得到:
<?php
function gen_pix($min, $max, $quantity) {
$numbers = range($min, $max);
shuffle($numbers);
$x_arr = array_slice($numbers, 0, $quantity);
foreach ($x_arr as $key => $value) {
$username = "https://graph.facebook.com/" . $value . "/";
$data = file_get_contents($username);
// if ($data===FALSE) { continue; }
$json = json_decode($data, true);
if (!isset($json['name'])) {
echo "Invalid ID<br />";
}
else {
echo $json["name"]. '<br />';
}
}
}
$x = 337800042;
$y = 337800382;
$z = 50;
gen_pix($x,$y,$z);
?>
我自己设置了行if ($data===FALSE) { continue; }
,虽然它解决不了多少。似乎 file_get_contents 请求运行良好,但有时(好吧,在大多数情况下)会返回错误JSON,如下所示:
{
"error": {
"message": "Unsupported get request.",
"type": "GraphMethodException",
"code": 100
}
}
虽然您也可以处理它并打印“无效ID”。
我的第一个想法是,你的服务器是否支持file_get_contents
,你的error_reporting是吗?
ini_set("display_errors",1);
error_reporting(E_ALL);
...
if (function_exists("file_get_contents")) {
file_get_contents("...")
}
修改强>
只是为了验证最长执行时间.. 你能否以某种方式验证呼叫是否需要更长时间:
echo ini_get("max_execution_time");
编辑2:
因此allow_url_fopen已停用,因此您根本无法使用 file_get_contents ,或启用 allow_url_fopen 。 您可能需要使用cURL或fsockopen,这里是一个简单的代码(也可能会被禁用)
if (!function_exists("curl_init")){
echo "Sorry cURL is not supported either!";
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "THE_URL");
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 60); // 60 seconds timeout
$json = curl_exec($ch);
curl_close($ch);
编辑3:
我的不好,只需从退货中删除标题:
curl_setopt($ch, CURLOPT_HEADER, 0);
另外,请求不使用SSL
$username = "http://graph.facebook.com/" . $value . "/";
最后,您仍然需要解码JSON:
$json = curl_exec($ch);
$json = json_decode($json, true);
