        addAuthor = $("#addAuthor").val(),
        addTranslator = $("#addTranslator").val(),
        addCover = $("#addCover").val(),
        addFormat = $("#addFormat").val(),
        addPrice = $("#addPrice").val(),
        addPublishDate = $("#addPublishDate").val(),
        addSummary = $("#addSummary").val(),
        addPublisher = $("#addPublisher").val(),
        addPages = $("#addPages").val();
    var json = {
        name: addBookName,
        isbn10: addISBN10,
        isbn13: addISBN13,
        author: addAuthor,
        translator: addTranslator,
        images: addCover,
        binding: addFormat,
        price: addPrice,
        publicDate: addPublishDate,
        summary: addSummary,
        publisher: addPublisher,
        pages: addPages
    };

    $.ajax({
        type: "PUT",
        dataType: "json",
        url: "",
        data: json,
        success: function(data) {
            console.log(json)
            console.log(data)
            $('#table').bootstrapTable('prepend', json);
        }
    })
})

同样的参数，使用postman发送是可以成功添加数据的

Answer 1

目测是请求头信息的问题，这个其实可以点开f12查看network，看下这个请求和postman发出去的请求有什么区别

Answer 2

ajax中加上contentType:"application/json" 试试?
