【问题描述】:
我正在尝试以每行 5 部电影的网格显示电影。我使用预定义的电影列表。我成功从https://api.themoviedb.org/4/list/1获取数据。
这是我的代码:
import QtQuick 2.15
import QtQuick.Window 2.15
Window {
width: 1920
height: 1080
visible: true
title: qsTr("Hello World")
Component.onCompleted: {
mojgrid.focus = true
}
function dobioResponseNapraviModel(response) {
console.log("dobioResponseNapraviModel", typeof response)
mojgrid.model=response
}
function request(){
console.log("BOK")
const xhr=new XMLHttpRequest()
const method="GET";
const url="http://api.themoviedb.org/4/list/1";
xhr.open(method, url, true);
xhr.setRequestHeader( "Authorization", 'Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJhdWQiOiI5YjBkOGVlMGQzODdiNjdhYTY0ZjAzZDllODM5MmViMyIsInN1YiI6IjU2MjlmNDBlYzNhMzY4MWI1ZTAwMTkxMyIsInNjb3BlcyI6WyJhcGlfcmVhZCJdLCJ2ZXJzaW9uIjoxfQ.UxgW0dUhS62m41KjqEf35RWfpw4ghCbnSmSq4bsB32o');
xhr.onreadystatechange=function(){
if(xhr.readyState===XMLHttpRequest.DONE){
var status=xhr.status;
if(status===0 || (status>=200 && status<400)){
//the request has been completed successfully
// console.log(xhr.responseText.results)
dobioResponseNapraviModel(JSON.parse(xhr.responseText).results)
}else{
console.log("There has been an error with the request", status, JSON.stringify(xhr.responseText))
}
}
}
xhr.send();
}
/* function request(url, callback) {
var xhr=new XMLHttpRequest();
xhr.open("GET", url, true)
xhr.onreadystatechange = function() {
if(xhr.readyState===4) {
callback(xhr.responseText)
}
}
xhr.open("GET", url)
xhr.setRequestHeader( "Authorization", 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJhdWQiOiI5YjBkOGVlMGQzODdiNjdhYTY0ZjAzZDllODM5MmViMyIsInN1YiI6IjU2MjlmNDBlYzNhMzY4MWI1ZTAwMTkxMyIsInNjb3BlcyI6WyJhcGlfcmVhZCJdLCJ2ZXJzaW9uIjoxfQ.UxgW0dUhS62m41KjqEf35RWfpw4ghCbnSmSq4bsB32o');
xhr.send()
}*/
GridView {
id:mojgrid
anchors.fill: parent
Keys.onUpPressed: {
request()
}
delegate: Rectangle{ id: rect; width:500;height: 400; color:'gray'
Image{ anchors.fill:parent
fillMode: Image.PreserveAspectFit
source:modelData.backdrop_path
}
Text{ text:modelData.original_title}
}
}
}
以下是我在运行应用程序时需要在 GridView 中显示的属性:
有人知道什么是错的吗?任何帮助将不胜感激,谢谢。
