我试图为我们的雇主，我有谷歌广告开发商令牌关键字搜索系统，但我无法找到任何CURL或PHP CURL安装指南。
两个参考链接Ad API Examples
Method: customers.generateKeywordIdeas

来自Google文档的示例：

curl -f --request POST "https://googleads.googleapis.com/v${API_VERSION}/customers/${CUSTOMER_ID}/campaignBudgets:mutate" \
--header "Content-Type: application/json" \
--header "developer-token: ${DEVELOPER_TOKEN}" \
--header "login-customer-id: ${MANAGER_CUSTOMER_ID}" \
--header "Authorization: Bearer ${OAUTH2_ACCESS_TOKEN}" \
--data "{
'operations': [
  {
    'create': {
      'name': 'My Campaign Budget #${RANDOM}',
      'amountMicros': 500000,
    }
  },
  {
    'create': {
      'name': 'My Campaign Budget #${RANDOM}',
      'amountMicros': 500000,
    }
  }
]
}"

我尝试此代码，但出现错误

<?
    
    $ch = curl_init();
    
    curl_setopt($ch, CURLOPT_URL, 'https://googleads.googleapis.com/v11/customers/(MANAGER_CUSTOMER_ID):generateKeywordIdeas');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, "{\n\n\"keywordSeed\": {\n    \"keywords\": [\n    \"cofee\"\n  ]\n  }\n}");
    
    $headers = array();
    $headers[] = 'Content-Type: application/json';
    $headers[] = 'Login-Customer-Id: (MANAGER_CUSTOMER_ID)';
    $headers[] = 'Developer-Token: DEVELOPER_TOKEN';
    $headers[] = 'Authorization: Bearer (OAUTH_ACCESS_TOKEN)';
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    
    $result = curl_exec($ch);
    if (curl_errno($ch)) {
        echo 'Error:' . curl_error($ch);
    }
    print_r($result);
    curl_close($ch);

没有任何输出
