上面的接口单独调用正常,问题出现在下面。应用的场景是:载入编辑页面时,调用接口,获得数据填充到页面。

Ajax cross-domain access,? ? Data confusion? ? .

页面真实代码

//编辑文章,载入页面时,获取编辑数据并填充页面
            $.ajax({
                url: '/api/article/getOne?id=' + id, //获取某条文章的信息
                type: 'get',
                dataType: 'json',
                beforeSend: function () {
                    $('#show_load').show();
                },
                success: function (article) {
                    console.log(article);
                    if (article.code != 200) return false;
                    $('#title').val(article.data.title); //文章标题
                    const content = htmlspecialchars_decode(article.data.content);
                    $('#summernote').summernote('code', content); //文章内容
                    $.ajax({
                        url: '/api/category/get', //获取所有分类
                        type: 'get',
                        dataType: 'json',
                        beforeSend: function () {
                            $('#show_load').show();
                        },
                        success: function (categorys) {
                            console.log(categorys); //问题出现在这里,打印出来的id全部为
                            if (categorys.code != 200) return false;
                            $('#categoryId').empty();
                            $('#categoryId').append(`<option value="0">请选择分类</option>`);
                            categorys.data.forEach(function (v) {
                                if(v.id = article.data.cateId){
                                    $('#categoryId').append(`<option value="${v.id}" selected>${v.name}</option>`)
                                }else{
                                    $('#categoryId').append(`<option value="${v.id}">${v.name}</option>`)
                                }
                            })

                        },
                        complete: function () {
                            $('#show_load').hide();
                        }
                    });

                },
                complete: function () {
                    $('#show_load').hide();
                }
            });

这时打印出来的数据如下:所有分类id全部变成“1”了。原来的文章分类id也确实是“1”。但是这里全部都变成1了,到底怎么回事?

之前这样写是可以正常工作的。但是今天不知道为什么变成这样了。迷茫了,^$^。

/api/category/get 这个获取所有分类的链接,你重新确认下(试着直接在浏览器中直接放上这个链接,看输出的内容是否id都为1,我看一般全都是1,像这种问题基本上可以被认为是后台获取分类的代码出错...)

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
