Cloudant CouchDB 文档更新冲突

Question

出于某种原因，我收到以下错误：

Fatal error: Uncaught exception 'PHPOnCouch\Exceptions\CouchConflictException' with message 'Conflict - Document update conflict.

Fatal error: Uncaught exception 'PHPOnCouch\Exceptions\CouchConflictException' with message 'Conflict - Document update conflict. (PUT /u12345/678bb21541f0ed5e67df1a9070000b55 [])' in /.../vendor/popojargo/php-on-couch/src/Exceptions/CouchException.php:74

我删除了修订版，所以我不确定为什么会发生文档更新冲突。

有没有人对此有任何见解？将不胜感激。

对象看起来像这样

{
  "_id": "678bb21541f0ed5e67df1a9070000b55",
  "_rev": "3-c0ea1980545a80839677d658eec0df78",
  "name": "Other",
  "timestamp": 0
}

我的代码

$userClient = new CouchClient("http://admin:pass@localhost:8080", "u12345");

$all_documents = $userClient->include_docs(TRUE)->getAllDocs();

foreach ($all_documents->rows as $d) {
    $doc = $d->doc;

    unset($doc->_rev);
    $doc->timestamp = 0;
    $userClient->storeDoc($doc);
}

Answer 1

更新文档时，需要提供_id。如果该文档已经存在，您必须提供 _rev.

当您从文档的本地副本中删除 _rev 时，更新它会导致冲突。为什么？您提供的文档没有 _rev，他们希望您提供最新的 _rev 以确认这将是下一个版本。
