我正在尝试从 Facebook 页面中提取墙上的帖子,但我遇到了问题。我在解析 Twitter 提要的 JSON 时没有问题,所以我看不出我遇到了什么问题。
这是我的代码,这是我用于帮助的教程:
<?php
$url = "http://www.facebook.com/feeds/page.php?format=json&id=96551536516";
function disguise_curl($url) {
$curl = curl_init();
$header[0] = "Accept: text/xml,application/xml,application/xhtml+xml,";
$header[0] .= "text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5";
$header[] = "Cache-Control: max-age=0";
$header[] = "Connection: keep-alive";
$header[] = "Keep-Alive: 300";
$header[] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7";
$header[] = "Accept-Language: en-us,en;q=0.5";
$header[] = "Pragma: ";
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla');
curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
curl_setopt($curl, CURLOPT_REFERER, '');
curl_setopt($curl, CURLOPT_ENCODING, 'gzip,deflate');
curl_setopt($curl, CURLOPT_AUTOREFERER, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_TIMEOUT, 10);
$html = curl_exec($curl);
curl_close($curl);
return $html;
}
$response = json_decode(disguise_curl($url));
foreach($response->entries as $block){
echo
"<li class='clearfix'>
<div class='streamPosterName'>{$block->author}</div>
<div class='postContent'>{$block->title}</div>
</li>";
}
?>
在我的页面的其他部分解析 JSON 时,我使用以下方法来引用 JSON 对象:
<?php
$url = "http://search.twitter.com/search.json?q=Apple&rpp=50";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$curlout = curl_exec($ch);
curl_close($ch);
$response = json_decode($curlout, true);
foreach($response["results"] as $block){
echo
"<li class='clearfix'>
<img src='".$block["profile_image_url"]."' />
<div class='streamPosterName'>".$block["from_user_name"]."</div>
<div class='streamPosterUsername'>@".$block["from_user"]."</div>
<div class='postContent'>".$block["text"]."</div>
</li>";
}
?>
前面的代码正确地提取了推文。Facebook 解析提供以下错误:
可捕获的致命错误:第 260 行的 /home/public_html/mkt/index.php 中的类 stdClass 的对象无法转换为字符串
第 260 行如上图所示:
<div class='streamPosterName'>{$block->author}</div>
