<p>我有一个使用JavaScript调用API的函数，运行得很好：</p>
<p><br /></p>
<pre class="brush:js;toolbar:false;">var headers = {
Authorization: "Bearer " + MY_ACCESS_TOKEN
};
var requestParams = {
method: "POST",
contentType: "application/json",
headers: headers,
payload: JSON.stringify({
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}}}}'
})
var response = UrlFetchApp.fetch(MY_API_ENDPOINT, requestParams);
var data = JSON.parse(response);</pre>
<p><br /></p>
<p>当我尝试将其转换为PHP时，我只从API得到一个空白的响应。我做错了什么？</p><p>
请注意，当我使用my_curl()从API检索$MY_ACCESS_TOKEN时，它的工作正常。</p>
<pre class="brush:php;toolbar:false;">$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,
$postdata
);
$data = my_curl ($endpoint, $headers);
var_dump ($data);
function my_curl ($endpoint, $headers) {
$ch = curl_init ();
curl_setopt ($ch, CURLOPT_URL, $endpoint);
curl_setopt ($ch, CURLOPT_POST, 1);
curl_setopt ($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt ($ch, CURLOPT_HEADER, false);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
$server_output = curl_exec($ch);
curl_close ($ch);
$json = json_decode ($server_output, true);
return ($json);
}
</pre>

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); ?>
