我目前正在编写一个PHP脚本来编译来自多个不同CSV的数据，并将组合文档导入Mongo。在此过程中，我在更新期间因光标超时而遇到错误。在这里看到（包含$ line和$ voterId的var_dump（））：
PHP Fatal error: Uncaught exception 'MongoCursorTimeoutException' with message 'localhost:27017: Read timed out after reading 0 bytes, waited for 30.000000 seconds' in /Users/georgeyates/Projects/cerebro-jobs/cavers-parse-phone.php:40
Stack trace:
#0 cavers-parse-phone.php(40): MongoCollection->update(Array, Array)
#1 {main}
thrown in cavers-parse-phone.php on line 40
Fatal error: Uncaught exception 'MongoCursorTimeoutException' with message 'localhost:27017: Read timed out after reading 0 bytes, waited for 30.000000 seconds' in /Users/georgeyates/Projects/cerebro-jobs/cavers-parse-phone.php:40
Stack trace:

更新搜索条件中的“Id”字段已编制索引，并且通过Mongo控制台或PHP执行的查找是亚秒级。此外，如果我通过Mongo控制台手动运行更新，则没有问题，它会在亚秒内运行。这是我的PHP代码，$ voterId和$ line分别是一个有效的字符串和数组：
$db->Voters->update(array(
array(
"Id" => $voterId
)
),
array(
'$push' => array(
"PhoneCalls" => $line
)
));
目前在开发过程中，我已经在我的机器上本地运行了整个过程。有趣的是，当我退出mongod进程时，我看到在退出过程中转储的日志中的查询向我表明更新存在问题。您可以看到从启动到退出的单个服务器会话日志，只有下面运行的单个更新查询：

您可以在该转储的第19行中看到转储的查询。
非常感谢您的时间，如果还有其他信息，请告诉我。
根据要求，这是$voterId和$line的var_dump（）：

这是system.indexes集合，显示Id字段确实已编入索引：
{ "v" : 1, "key" : { "_id" : 1 }, "ns" : "cavers-import.Voters", "name" : "_id_" }
{ "v" : 1, "key" : { "Id" : 1 }, "ns" : "cavers-import.Voters", "name" : "Id_1" }
答案 0 :(得分：1)
我认为答案是围绕查询的一个简单的一个太多的数组：
$db->Voters->update(array(
array(
"Id" => $voterId
)
), ...
实际应该是：
$db->Voters->update(
array(
"Id" => $voterId
), ...
如果我将查询包装在另一组括号中，就像这个问题中的情况一样，mongo shell会引发错误。
在mongo shell中，您的查询将如下所示：
db.Voters.update({{Id: voterId}}, {update info here ...});
哪个不正确
