app端怎么使用uni.loadFontFace引入本地字体呀？

uni.loadFontFace({  
                        family:fontFamily,  
                        source:`url(/var/mobile/Containers/Data/Application/F36F399D-F596-4CDD-A522-79BC3B6E844E/Documents/Pandora/apps/HBuilder/www/"_doc/uniapp_temp_1725267368011/download/兵克侠客体.ttf")`,  
                        //source:`url(${this.displayedFonts[i].localityUrl})`,  
                        success:(res) => {  
                            this.selectedLayer.style.fontFamily = fontFamily;  
                            this.displayedFonts[i].loaded = true;  
                            console.log(res)  
                            this.displayedFonts[i].download = true;  
                            this.setLayerText(this.selectedLayer, this.selectedLayer.srcText);  

                        },  
                        fail: (res)=> {  
                            this.displayedFonts[i].download = false;  
                            console.log(res)  
                        },  
                    })

报错："errMsg": "loadFontFace:fail SyntaxError: The string did not match the expected pattern."
这个路径已经转成平台绝对路径了，求求大佬帮帮小白吧
