如何从角度的嵌套json数组中获取值？

Question

I want to fetch the value from the nested json array in angular2. I want to fetch the client_id from the following json array:

{ "resources" : [ {

 "scope" : [ "clients.read", "clients.write" ], "client_id" : "tc53EZ", "resource_ids" : [ "none" ], "authorized_grant_types" : [ "client_credentials" ], "redirect_uri" : [ "http://ant.path.wildcard/**/passback/*", "http://test1.com" ], "autoapprove" : [ "true" ], "authorities" : [ "clients.read", "clients.write" ], "token_salt" : "C7NBIz", "allowedproviders" : [ "uaa", "ldap", "my-saml-provider" ], "name" : "My Client Name", "lastModified" : 1512452520895 } ], 

"startIndex" : 1, "itemsPerPage" : 1, "totalResults" : 1,
"schemas" : [ " http://cloudfoundry.org/schema/scim/oauth-clients-1.0 " ] }

Can anyone help me out.

Thanks & Regards

If your data will be single resources

    public getClientId(data) {
      let allClients: string[] = [];
      if(data && data.resources && data.resources.length > 0) {
        data.resources.forEach((d, i) => {
          allClients.push(d.client_id);
          if(data.resources.length === i + 1) {
            this.clients = allClients; // clients will be array of type number and will be declared in component
          }
        });
      } else
        return null;
    }

If you want all client_id from resources (resources will have multiple data) then let me know i will update answer.
