当使用json_encode时,应该提供一个关联数组或一个要编码为JSON的对象,而不是一个字符串。在你的情况下,你提供了一个字符串,你在$headers数组中混合了头部和post数据。我已经添加了缺失的CURLOPT_POSTFIELDS选项,以便在cURL请求中包含JSON编码的post数据,使API能够正确接收查询。
<?php $MY_ACCESS_TOKEN = "your_access_token"; $MY_ADSET_ID = "your_adset_id"; $MY_API_ENDPOINT = "your_api_endpoint"; $postdata = json_encode([ 'query' => 'query {adSet(id: "' . $MY_ADSET_ID . '") {insights(timeRange: {from: "2023-08-01T00:00:00Z", until: "2023-08-10T23:59:59Z"} timeIncrement: DAILY) {timestamps reports {impressions conversions offerwallImpressions offerwallAverageRank spend}}}}' ]); $endpoint = $MY_API_ENDPOINT; $headers = array( "Content-Type: application/json", "Authorization: Bearer " . $MY_ACCESS_TOKEN ); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $endpoint); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $server_output = curl_exec($ch); curl_close($ch); $json = json_decode($server_output, true); var_dump($json); ?>
