我使用两个JSON提要源和PHP来显示网站上代理的房地产属性幻灯片。代码在供稿提供商更改其存储属性和代理图像的位置之前工作。我已对图像进行了必要的调整,但Feed数据现在无法正常工作。我已经就这个问题联系了饲料供应商,但他们说问题就在我身边。除了图像URL之外没有任何更改,因此我不确定问题的位置。我是JSON的新手,所以我可能会遗漏一些东西。我已经在下面添加了完整的脚本。以下是两个JSON供稿网址:http://century21.ca/FeaturedDataHandler.c?DataType=4&EntityType=2&EntityID=2119和http://century21.ca/FeaturedDataHandler.c?DataType=3&AgentID=27830&RotationType=1。第一个URL抓取所有代理,第二个URL抓取单个代理的属性。 AgentID值源自JSON提要URL。

JSON
不是有效的JSON
,这就是为什么你没有收到结果,因为PHP
无法decode
进料。
我试图处理它,并收到此错误
错误:第1行的解析错误: {道具:[{地址:“28 - ^ 期待'STRING','}'
第一个网址的Feed图片
这是第二个网址的Feed
的视图根据第二次Feed的错误,所有keys
都应该包含在"
内,因为它们是strings
而不是CONSTANTS
。
e.g。
Props
应该是"Props"
,也应该是function
。

您需要更新formatJSON($json)
并将此class
添加到// Update this function, just need to update last line of function
function getProperties($agent_id)
{
$url = $this->base_url.'/FeaturedDataHandler.c?DataType=3'.'&AgentID='.$agent_id.'&RotationType=1';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
$response = curl_exec($ch);
curl_close($ch);
$json = json_decode($response);
if (empty($response))
die('No response 2'); //return false;
else
return $this->formatJSON($this->decode_json_string($response)); //this one only need to be updated.
}
//add this function to class. This will format json
private function formatJSON($json){
$from= array('Props:', 'Success:', 'Address:', ',Price:', 'PicTicks:', ',Image:', 'Link:', 'MissingImage:', 'ShowingCount:', 'ShowcaseHD:', 'ListingStatusCode:', 'Bedrooms:', 'Bathrooms:', 'IsSold:', 'ShowSoldPrice:', 'SqFootage:', 'YearBuilt:', 'Style:', 'PriceTypeDesc:');

return str_ireplace($from, $to, $json); //returns the clean JSON
}
decode_json_string($json)

我已经测试过该功能,并且工作正常,可能是您的功能出现了问题json
我从第二个网址中删除了不清楚的json
,并将其清除 here ,并将清除后的composer require mxkh/url-finder
放入json编辑器中以检查其是否正常工作是否 HERE

尝试使用此代码修复JSON:
$url = 'http://century21.ca/FeaturedDataHandler.c?DataType=3&AgentID=27830&RotationType=1';
$invalid_json = file_get_contents($url);
$json = preg_replace("/([{,])([a-zA-Z][^: ]+):/", "$1\"$2\":", $invalid_json);
var_dump($json);
