Uniapp https双向认证问题

https请求后台，host参数不管写什么，返回结果都是success，内容为configMTLS:errMsg = configMTLS:ok，code = 0，求教各位大佬，帮忙解决

            aaa(){  
                uni.configMTLS({  
                    certificates: [{  
                        'host': '192.168.191.2',  
                        'client': '/static/client.p12',  
                        'clientPassword': '123456',  
                        'server': ['/static/server.cer']  
                    }],  
                    success (res) {  
                        var description = "";  
                        for (var i in res) {  
                            description += i + " = " + res[i] + "\n";  
                        }  
                        console.log('configMTLS:' + description)  
                    }  
                });  
            }
