JSON 在 Django 中进行国际化的本地文件检索

Question

我正在用 django 制作一个网站，并且包含了国际化。国际化在其他页面上工作正常，除了当我试图检索 json 文件时。

搜索取一个词，然后在javascript文件（下）中找到对应的JSON文件。在我添加国际化之前，搜索一直没有问题。现在可以看到jquery去获取文件的时候，前面包含了i18n缩写，导致500错误。我尝试解析文件位置，但缩写总是添加到 getJSON 中。我该如何解决这个问题？

控制台中具体显示的错误是：

获取 http://localhost:8000/en/static/assets/chowords/amo.json 500（内部服务器错误）

这是一个错误是有道理的，因为 json 文件实际上位于 http://localhost:8000/static/assets/chowords/amo.json 我尝试将文件存储在目录“en”中，其中嵌套了 static，但这并没有解决问题。

参考代码：

Javascript 文件

new URLSearchParams(window.location.search).forEach((value,name)=>{

    console.log(name)
    console.log(value)
    var fileword = value;

    var url = "./static/assets/chowords/" + fileword + ".json";

    var xhr = new XMLHttpRequest();
    xhr.open('HEAD', url, false);
    xhr.send();
    console.log(xhr)

    document.getElementById("wordsearched").innerHTML =`<h1>${fileword} </h1>`

    if (xhr.status == "404") {
        //console.log("File doesn't exists");
        let div = document.createElement('p')
        div.innerHTML =`<h3>No results found</h3>`
        document.getElementById("word").appendChild(div)

    } else  {
        console.log("here");
        $.getJSON("static/assets/chowords/" + fileword + ".json", function(data){

                var senses = data['sense'];
                console.log(senses.length)
                var audios = data['audio']
                var variant = data['variant']

                for (var i = 0; i <senses.length; i++){
                    let wording = senses[i];
                    wordtemplate(wording, audios, variant)
                }
            });
    }
    })

非常感谢您对此提供的任何帮助！

Answer 1

这是相对路径

 $.getJSON("static/assets/chowords/"...

改为

$.getJSON("/static/assets/chowords/"...

所以它变得绝对。

此外，要查看错误消息，您可以进入开发人员工具中的“网络”选项卡，select 出错的请求然后转到预览选项卡。
