为什么我在AngularJs中的http.delete时无法传递参数？

I have function to call http.delete and pass a parameter flag:

我有调用http.delete并传递参数标志的函数:

function softDeleteDatasource(datasourceId,flag) {
            var url = baseUrl + datasourceId;
            return $http.delete(url, {'currentFieldSetFlag':flag});
        }

Then I assume I can get the req.body with following code. However, I always get undefined in the console.log. I used exactly same code in http.post and it works fine when passing parameter.

然后我假设我可以使用以下代码获取req.body。但是,我总是在console.log中未定义。我在http.post中使用完全相同的代码,它在传递参数时工作正常。

var bodyParser = require('body-parser');
var jsonParser = bodyParser.json();
router.delete('/:datasourceId', jsonParser, function(req, res) {
   console.log(req.body.currentFieldSetFlag);
}

I am confused why the same code can not pass parameter in http.delete? anyone know how to pass it?

我很困惑为什么相同的代码不能在http.delete中传递参数?谁知道怎么通过呢?

The HTTP spec allows for bodies on DELETEs, but some clients do not send them and some proxies/servers will strip/ignore them if present. This ought to work to pass it as a querystring parameter:

HTTP规范允许DELETE的主体,但是一些客户端不发送它们,并且一些代理/服务器将剥离/忽略它们(如果存在)。这应该将它作为查询字符串参数传递:

return $http.delete(url, {params: {'currentFieldSetFlag':flag}});
