Question

我试图根据这里的说明编写PHP脚本：

https://developers.facebook.com/ads/blog/post/2016/12/18/lead-ads-offline/

但是我遇到了一个json字符串问题，它在PHP中作为参数传递给curl。看起来它正在添加反斜杠（＆＃34; match_keys＆＃34;：＆＃34;无效密钥\＆＃34; email \＆＃34;等等）导致API调用失败。< / p>

我试过玩：

json_encode($array,JSON_UNESCAPED_SLASHES);

我已经尝试了一堆SO答案，就像Curl add backslashes但没有运气。

<?php

$email = hash('sha256', 'test@gmail.com');

$data = array("match_keys" => '{"email": $email}',
              "event_time" =>1477632399,
              "event_name"=> "Purchase",
              "currency"=> "USD",
              "value"=> 2.00);

$fields = [
            // 'upload_tag'=>'2016-10-28-conversions',
            'access_token'=>'#######',
            'data'=> $data
        ];


$url = 'https://graph.facebook.com/v2.8/#######/events';

echo httpPost($url, $fields);


function httpPost($url, $fields)
{
    $curl = curl_init($url);
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($fields));
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    $response = curl_exec($curl);
    curl_close($curl);
    return $response;
}


?>

这是回复：

Array{"error":{"message":"(#100) Invalid parameter","type":"OAuthException","code":100,"error_data":{"match_keys":"Invalid keys \"email\" were found in param \"data[match_keys]\".","event_time":"Out of bounds array access: invalid index match_keys","event_name":"Out of bounds array access: invalid index match_keys","currency":"Out of bounds array access: invalid index match_keys","value":"Out of bounds array access: invalid index match_keys"},"fbtrace_id":"BrVDnZPR99A"}}%

您正在将JSON与PHP数组混合使用。我怀疑它实际上是您打算用来发送数据的JSON，因为您正在使用http_build_query。试试这个：

$data = array("match_keys" => ["email" => $email], 
  "event_time" =>1477632399,
  "event_name"=> "Purchase",
  "currency"=> "USD",
  "value"=> 2.00
);

这样，您可以将数据定义为数组，并让http_build_query为您进行编码。

PHP为我的CURL命令添加反斜杠，用于Facebook离线转换
