我被困在这。我试图从远程服务器上获取动态生成的JSON数据。这里只是URL生成JSON：获取外部JSON数据。 jQuery + AJAX的作品。 PHP + cURL不是
https://www.librarything.com/api_getdata.php?userid=jtodd1973&key=1962548278&max=1&responseType=json
我能够访问使用jQuery/AJAX数据的罚款。下面是我使用jtodd.info/librarything.php代码：
<div id="booklist">
<table id="tbl_books" style="width:80%; border: thin solid black;">
<tr style="border: thin solid black; background-color: #666; color: #fff;">
<th style="width:40%;">Title</th>
<th style="width:30%;">Author</th>
<th style="width:10%;">Rating</th>
<th style="width:20%;">Reading dates</th>
</tr>
</table>
</div>
<script type="text/javascript">
$(document).ready(function() {
$.ajax({
type:'POST',
callback: 'callback',
crossDomain: true,
contentType: 'application/json; charset=utf-8',
dataType:'JSONP',
beforeSend: function setHeader(xhr){ xhr.setRequestHeader('accept', 'application/json'); },
url:'https://www.librarything.com/api_getdata.php?userid=jtodd1973&key=1962548278&booksort=title&showTags=1&showCollections=1&showDates=1&showRatings=1&max=1000',
success:function(data) {
x = 0;
var data1 = JSON.stringify(data);
var data2 = JSON.parse(data1);
$.each(data2.books, function(i,book){
var date1 = Number(1420027199);
var date2 = Number(book.entry_stamp);
if (date2 > date1) {
x = x + 1;
var testTitle = book.title;
var n = testTitle.indexOf(" (");
if(n > -1) {
var bookTitle = testTitle.substr(0, n);
} else {
var bookTitle = testTitle;
}
var bookAuthor = book.author_lf;
var bookRating = book.rating;
if(x % 2 == 0){
var rowColor = "#fff";
} else {
var rowColor = "#ccc";
}
$('#booklist table').append('<tr style="background-color:' + rowColor + ';">' +
'<td style="font-style: italic;">' + bookTitle +
'</td><td>' + bookAuthor +
'</td><td style="text-align: center;">' + bookRating +
'</td><td> ' +
'</td></tr>');
}
});
},
error:function() {
alert("Sorry, I can't get the feed");
}
});
});
</script>
但是，我不能使用PHP &卷曲访问数据。我没有收到服务器的回应。更具体地讲，我得到错误号7/HTTP代码0这里是我使用的jtodd.info/librarything2.php代码：
<?php
$url = 'https://www.librarything.com/api_getdata.php?userid=jtodd1973&key=1962548278&max=1&responseType=json';
$result = get_web_page($url);
if ($result['errno'] != 0)
echo "<p>Error number = " . $result['errno'] . "</p>";
if ($result['http_code'] != 200)
echo "<p>HTTP code = " . $result['http_code'] . "</p>";
$page = $result['content'];
echo "<pre>" . $page . "</pre>";
function get_web_page($url) {
if(!function_exists("curl_init")) die("cURL extension is not installed");
$ch = curl_init();
$options = array(
CURLOPT_URL => $url,
CURLOPT_RETURNTRANSFER => true, // return web page
CURLOPT_HEADER => true, // don't return headers
CURLOPT_FOLLOWLOCATION => true, // follow redirects
CURLOPT_ENCODING => "", // handle all encodings
CURLOPT_USERAGENT => "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.2 (KHTML, like Gecko) Chrome/22.0.1216.0 Safari/537.2", // who am i
CURLOPT_AUTOREFERER => true, // set referer on redirect
CURLOPT_CONNECTTIMEOUT => 120, // timeout on connect
CURLOPT_TIMEOUT => 120, // timeout on response
CURLOPT_MAXREDIRS => 10, // stop after 10 redirects
CURLOPT_SSL_VERIFYPEER => false // Disabled SSL Cert checks
);
curl_setopt_array($ch, $options);
$content = curl_exec($ch);
$err = curl_errno($ch);
$errmsg = curl_error($ch);
$header = curl_getinfo($ch);
curl_close($ch);
$header['errno'] = $err;
$header['errmsg'] = $errmsg;
$header['content'] = $content;
return $header;
}

感谢您的任何意见。
你的代码对我来说工作得很好。 – 2015-02-11 21:10:17
