将文档从AngularJS发布到SOLR 4

I.在SOLRsolr-4.7.0 / example / solr-webapp / webapp / WEB-INF / web.xml附带的Jetty服务器上配置CORS

注意：CrossOriginFilter有一个参数chainPreflight,默认情况下设置为true.这需要设置为false.这是CORS转发POST而不是SOLTIONS的关键.此外,订单很重要！

<filter>
    <filter-name>cross-origin</filter-name>
    <filter-class>org.eclipse.jetty.servlets.CrossOriginFilter</filter-class>
    <init-param>
         <param-name>allowedOrigins</param-name>
         <param-value>http://localhost*</param-value>
    </init-param>
     <init-param>
         <param-name>allowedMethods</param-name>
         <param-value>GET,OPTIONS</param-value>
     </init-param>
     <init-param>
         <param-name>allowedHeaders</param-name>
         <param-value>origin,options,authorization,x-requested-with</param-value>
     </init-param>
    <init-param>
        <param-name>supportsCredentials</param-name>
        <param-value>true</param-value>
    </init-param>
    <init-param>
      <param-name>chainPreflight</param-name>
      <param-value>false</param-value>
    </init-param>
</filter>

<filter-mapping>
  <filter-name>cross-origin</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

II. SOLR期望以数组格式的有效载荷,因此您需要将Angular对象推入一个.基本上,$scope.data变为[$scope.data]

assayControllers.controller('AssayUpdateController',['$scope','$http','$location',function($scope,$http,$location){
        $scope.processForm = function(){
            $http.post("http://localhost:8983/solr/mrm_assay/update?commit=true",[$scope.assay])
                .success(function(data,headers){
                    console.log(data.message);
                    $location.path("/assays")
                })
                .error(function(data,config){
                    console.log(status);
                });
        };
    }
]);

III. SOLR文档包含可能导致POST出现“冲突”错误的版本字段.这是由于我无法追踪的缓存问题(卷曲显示当前值但浏览器有旧版;甚至强制刷新).无论如何,这对SOLR来说比我更有用,所以最好的办法是不要首先将它归还给客户.我不认为字段排除是一个选项,因此我将所有要在solrconfig.xml中返回的字段列入白名单

<!-- A request handler that returns indented JSON by default -->
  <requestHandler name="/query" class="solr.SearchHandler">
     <lst name="defaults">
       <str name="echoParams">explicit</str>
       <str name="wt">json</str>
       <str name="indent">true</str>
       <str name="df">text</str>
      <str name="fl">uuid,keep_in_assay,detected_endog,problems_w_is,onc_std_set,fraction_id,detected_by_orbi_experiments,onclistgene,geneid,taxonid,peptide,
degen_human,degen_mouse,gene_degeneracy,department,protein_ac,pepid,protid,percnt_id,peptide_ordered</str>

现在该应用程序就像一个魅力！
