我是REST的新手,只想使用ROQL从查询SELECT ID from CO.A_Country where Name="xxx";获取ID。我在PHP中使用REST:
<?php
/**
* Example API call
* GET profile information
*/
// the ID of the profile
$profileID = 2;
// the token
$token = 'your token here';
// set up the curl resource
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,
"https://User:Pass@test.help.com/services/rest/connect/v1.3/queryResults
/?query=select%20ID%20from%20CO.A_Country%20where%20CO.A_Country.A_Country=%27xxx%27");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
$output = curl_exec($ch);
echo($output). PHP_EOL;
curl_close($ch);?>
我得到的结果如下:
HTTP/1.1 200 OK Date: Thu, 04 Aug 2016 14:58:02 GMT Server: Apache Content-Language: en-US RNT-Time: D=58455 t=1470322682582920 RNT-Machine: 128.64 Transfer-Encoding: chunked Content-Type: application/json { "items": [ { "tableName": "CO.Affected_Country", "count": 1, "columnNames": [ "id" ], "rows": [ [ "12" ] ] } ], "links": [ { "rel": "self", "href": "https://test.help.com/services/rest/connect/v1.3/queryResults?query=select%20ID%20from%20CO.A_Country%20where%20CO.A_Country.Affected_Country=%27USA%27" }, { "rel": "canonical", "href": "https://test.help.com/services/rest/connect/v1.3/queryResults" }, { "rel": "describedby", "href": "https://test.help.com/services/rest/connect/v1.3/metadata-catalog/queryResults", "mediaType": "application/schema+json" } ] }
如何在$output中只获得所需的ID?

您不能只从ROQL查询中从OSvC REST获取ID;特别是因为您的查询可以返回多个结果。其他数据将始终作为结果的一部分返回(以及其他相关数据,具体取决于您使用的端点)。您需要解析这些结果才能从查询中获得ID。
不要将标题作为响应主体的一部分返回:
curl_setopt($ch, CURLOPT_HEADER, 0);
然后使用json_decode将ROQL结果转换为PHP对象,就像@Manish建议的那样。
$results = json_decode($output);
然后,您的ROQL结果是可解析的。行作为可以循环遍历的数组返回。由于您的查询没有限制语句,所以应该添加该语句或说明返回的多个值。
if(!is_null($results['items'][0]['rows'])){ foreach($results['items'][0]['rows'] as $row){ echo $row; //Will output the ID from your select statement. Change this to do something with the ID as needed. } }

基本上curl是以json的形式返回完整的数据。首先,将这些数据转换为php,然后遍历该数组以找到确切的值。您可以使用json_decode函数。有关功能的更多细节,请参考以下内容。http://php.net/manual/en/function.json-decode.php
