Question

我正在尝试从照明组件下载几个文件。我无法将内容文档ID列表附加到url。请帮忙。

当我将多个ID添加到带有正斜杠的url中时，我能够一次下载所有文档。因此，我相信我可以将Ids列表直接传递给url。但无法做到。我尝试了以下选项，但没有任何运气：下载下载`

COMPONENT:
<aura:component controller="MassFileDownload" implements="force:appHostable,force:hasRecordId,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes,force:lightningQuickAction" access="global">
    <aura:attribute name="listOfIds" type="String"/>  
    <aura:attribute name="resultList" type="List"/>  
    <aura:attribute name="isSuccess" type="Boolean"/>

        <div class="slds-form-element">
            <lightning:textarea name="list of ids" label="List of Ids" value="{!v.listOfIds}"/>    


            <aura:if isTrue="{!v.isSuccess}">
                <!--<a href="{!'/sfc/servlet.shepherd/document/download/'+resultList}" target="_blank">DOWNLOAD</a>-->
                <a href="{!'/sfc/servlet.shepherd/document/download/'&amp;resultList&amp;}" target="_blank">DOWNLOAD</a>
            </aura:if>

        </div>

    <!-- BUTTON -->
    <div class="slds-p-top_xx-large">
           <button type="button" onclick="{!c.massDownload}" >Download</button> 
    </div>

</aura:component>

CONTROLLER:
({
    massDownload : function(component, event, helper) {
        console.log('111111111');
        //var listIds = component.get("v.listOfIds");
        helper.getSRId(component, event, helper);
    }
})

HELPER:
({
    getSRId : function(component,event,helper) {
        console.log('2222222222');
        console.log('33333333333'+ component.get("v.listOfIds"));
        var action = component.get("c.GetContentDocLink");
        console.log('4444444444' + action);
        action.setParams({
            'listLinkedEntity': component.get("v.listOfIds")
        });

        action.setCallback(this,function(response){
            console.log('555555555555');
            console.log('cow');
           var state = response.getState();
            if (state === "SUCCESS") {
                console.log('dog');

                var storeResponse = response.getReturnValue();
                component.set("v.resultList", storeResponse);
                component.set("v.isSuccess",true);
                if (storeResponse.length == 0) {
                    console.log('snake' + storeResponse.length);
                }               
                }else{
                console.log('rabbit');
                 }
            console.log('dog' + storeResponse.length);
                // set searchResult list with return value from server.
                //component.set("v.resultList", storeResponse);
                console.log('owl' + storeResponse);
                console.log('zebra' + component.get("v.resultList"));
        }) 
        $A.enqueueAction(action); 
    }
})

APEX:

public class MassFileDownload{

    @AuraEnabled
    public static List<String> GetContentDocLink(String listLinkedEntity){
    list<String> returnList = new List<String>();
    returnList=listLinkedEntity.split(',');
    List<String> listWithSlash = new List<String>();
    system.debug('aaaaaaaaa'+ listLinkedEntity + returnList);
        List<String> listCDId = new List<String>();
        List<String> listCDIdAll = new List<String>();
        for(ContentDocumentLink cdl : [Select Id,ContentDocumentId,LinkedEntityId from ContentDocumentLink where LinkedEntityId in : returnList]){
            system.debug('cccccccccccc'+cdl);
            listCDId.add(cdl.ContentDocumentId);
        }

        for(Integer i = 0;i<listCDId.size();i++){
            listWithSlash.add(listCDId[i]+'/');
            //listWithSlash = listWithSlash+listCDId[i]+'/';
        }

        system.debug('bbbbbbbbbbb'+listCDId);
        return listWithSlash;
    }}

当我尝试保存组件时，出现以下错误：

未能保存MassDownload.cmp：期望为“＆”，在表达式“ /sfc/servlet.shepherd/document/download/?”&resultList&：Source

的第45列中找到“ r”

将ID列表附加到url中
