PHP curl请求API

<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> <p><br /></p>

    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);
    ?>
