布尔检查在NodeJS中不起作用

Question

我正在开发节点js API,我正在通过URL查询数据

get_posts_default?pageId=ge4JqBn9F0srzHnVFHmh&asking_post=false&asking_responce=false&maxSort=-1&minSort=-1&limit=20

这是负责处理此请求的函数

 public async get_poset_list(userDeta: hs_I_fb_en_user_auth_paylode,pageId:string,asking_post:boolean,asking_responce:boolean,maxSort:number,minSort:number,limit:number):Promise<hs_I_fb_en_post_return[]>{
        try {
            hs_d_w("Is asking post: - "+asking_post);
            hs_d_w("Limit: - "+limit);
            if(asking_post===true){  
                hs_d_w("Asking post true");
                if(minSort<=-1 && maxSort<=-1){
                    hs_d_w("Asking post Defolt");
                    return this._postQueryes.get_only_poses(pageId,limit);
                }else{
                    if(minSort>-1){
                        hs_d_w("Asking post MIn");
                        return this._postQueryes.get_only_poses_min(pageId,minSort,limit);
                    }
                    if(maxSort>-1){
                        hs_d_w("Asking post Max");
                        return this._postQueryes.get_only_poses_max(pageId,maxSort,limit);
                    } 
                    hs_d_w("Asking post None");
                    return [];
                }
            }else{
                if(minSort<=-1 && maxSort<=-1){
                    hs_d_w("Asking talk Defolt");
                    return this._postQueryes.get_only_talkes(pageId,limit);
                }else{
                    if(minSort>-1){
                        hs_d_w("Asking talk min");
                        return this._postQueryes.get_only_talkes_min(pageId,minSort,limit);
                    }
                    if(maxSort>-1){
                        hs_d_w("Asking talk max");
                        return this._postQueryes.get_only_talkes_max(pageId,maxSort,limit);
                    }
                    hs_d_w("Asking talk none");
                    return [];
                }
            }
        } catch (e) {
            hs_d_w("get_poset_list : " + e);
            return Promise.reject(e)
        }
    }

现在如果我调用set calling_post = false或ask_post = true,它总是调用此函数的主要else区域

return this._postQueryes.get_only_talkes(pageId,limit);

这个.

我不明白为什么会这样？有人可以帮我这个吗？

Answer 1

当你得到req.query它的东西时总会返回一个String.因此,请确保将其转换为布尔值

const variable = (variable == 'true')
// or
const variable = (variable === 'true')

另外,当变量是布尔值时,您不必显式检查===.这也行

if(foo) {

} else {

}

编辑:正如@Kamalakannan所说Boolean('string')不会奏效.我很抱歉.
