使用 Solr 添加數據時出錯 - Solr HTTP 錯誤：OK (409)(HttpException)

Question

我已經嘗試了很長時間了，我什至在谷歌上搜索了很多。

我在 Laravel 中嘗試使用 Solarium 將數據添加到 Solr 時遇到此錯誤，

(1/1) HttpException

Solr HTTP error: OK (409)
{
"responseHeader":{
"status":409,
"QTime":3},
"error":{
"metadata":[
"error-class","org.apache.solr.common.SolrException",
"root-error-class","org.apache.solr.common.SolrException"],
"msg":"version conflict for 12 expected=12435421423451 actual=-1",
"code":409}}
in Result.php line 106
at Result->__construct(object(Client), object(Query), object(Response))in Client.php line 753

這是我在 EmployeeController.php 中的函數

public function enterDataSolr()
{

    $update = $this->client->createUpdate();


    $doc1 = $update->createDocument();
    $doc1->Gender = "M";
    $doc1->Salary = 199999;

    $doc1->_version_ = 12435421423451;
    $doc1->score = 1;

    $doc2 = $update->createDocument();
    $doc2->Gender = "F";
    $doc2->Salary = '200000';
    $doc2->SSN = "0050-03-10T00:00:00Z";

    $doc2->score = 1;

    $update->addDocuments(array($doc1, $doc2));
    $update->addCommit();
    $result = $this->client->update($update); 

    echo '<b>Update query executed</b><br/>';
    echo 'Query status: ' . $result->getStatus(). '<br/>';
    echo 'Query time: ' . $result->getQueryTime();

}

當 ping() 函數返回狀態 OK 時，連接正確建立。 搜索功能也正常工作。 這是構造函數

 public function __construct(EmployeeRepository $emp_repository, Client $client)
{   
    $this->emp_repository = $emp_repository;
    $this->client = $client;
    //dd('Solarium library version: ' . Client::VERSION . ' - ');

}

我也用過課

use Solarium\Client;

Optimistic Concurrency是Solr一個特性，客戶端應用程序可以使用它來更新/替換文檔，以確保它們正在替換/更新的文檔沒有被另一個客戶端應用程序同時修改。

如果存在版本沖突（ HTTP error code 409 ），則客戶端重新開始該過程。

此功能的工作原理是要求索引中所有文檔的_version_字段，並將其與指定為更新命令一部分的版本進行比較。 默認情況下，Solr 的 Schema 包含一個_version_字段，該字段會自動添加到每個新文檔中。

$ curl -X POST -H 'Content-Type: application/json' 'http://localhost:8983/solr/techproducts/update?_version_=1632740120218042368&versions=true&commit=true&omitHeader=true' --data-binary '
[{ "id" : "aaa",
   "foo_s" : "update attempt with correct existing version" }]'

具有與索引中的值匹配的_version_值的更新，並且它成功。 因為我們在更新請求中包含了versions=true ，所以響應中的_version_字段包含不同的值。

如果在文檔本身中嵌入了_version_值的更新。 請求失敗，因為您指定了錯誤的版本。 下面是它的錯誤。

{
  "error":{
    "metadata":[
      "error-class","org.apache.solr.common.SolrException",
      "root-error-class","org.apache.solr.common.SolrException"],
    "msg":"version conflict for aaa expected=100 actual=1632740462042284032",
    "code":409
    }
}

有關更多詳細信息，請參閱 solr 文檔。

這里的 -1 意味着 Solr 無法找到具有該版本的文檔。 我建議您嘗試在 Solr 管理 UI 上手動發送其中一份文檔給 solr 自己。 選擇您的核心/集合名稱，然后單擊文檔鏈接（在 solr 管理頁面上），您將進入可以將文檔發送到 solr 以進行更新的頁面。
