<p>我有一個使用JavaScript呼叫API的函數，並且運作得很好：</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: "2023-08-10T23:59:00Z", 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>當我嘗試將其轉換為PHP時，我只從API中得到一個空白的回應。我做錯了什麼？ </p><p>
請注意，當我使用my_curl()從API檢索$MY_ACCESS_TOKEN時，它的工作正常。 </p>
<pre class="brush:php;toolbar:false;">$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>

當使用json_encode時，應該提供一個關聯數組或一個要編碼為JSON的對象，而不是一個字串。在你的情況下，你提供了一個字串，你在$headers陣列中混合了頭部和post資料。我已經添加了缺少的CURLOPT_POSTFIELDS選項，以便在cURL請求中包含JSON編碼的post數據，使API能夠正確接收查詢。
<?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); ?>
