javascript - 连接到服务器 AJAX 调用时出错

Question

我下面有这段代码，我正在尝试将数据发送到服务器，但我必须连接到它的唯一文档是发送到服务器的示例数据，它看起来像这样 {“method”:“fruit-post”,“data”:{“red-fruits”:["Apple","Cherry","Tomato"],“green-fruits”:["Grapes","Watermelon"],“yellow-fruits”:["Lemon","Pear"],“purple-fruits”:[]}}我在下面的代码中做错了什么吗，因为我不断收到错误 405 和 Response for preflight has invalid HTTP status code 405.任何帮助将不胜感激

var fruitData = {};

var key = "red-fruits";
fruitData[key] = red;

var key2 = "green-fruits";
fruitData[key2] = green;

var key3 = "yellow-fruits";
fruitData[key3] = yellow;

var key4 = "purple-fruits";
fruitData[key4] = purple;

var fruitString = JSON.stringify(fruitString);

$.ajax({
    method: "fruit-post", 
    type: "POST",
    url: "LINK",
    data: {
        "data": fruitString
    },
    cache: false,
    success: function(data) {
}

您的ajax请求是错误的。看这里http://api.jquery.com/jquery.ajax/

方法必须是 POST、GET 或 PUT

$.ajax({
  url: "LINK",
  method: "POST",
  data: {
        “method”:“fruit-post”,
        “data”:{
            “red-fruits”:["Apple","Cherry","Tomato"],
            “green-fruits”:["Grapes","Watermelon"],
            “yellow-fruits”:["Lemon","Pear"],
            “purple-fruits”:[]
        }
  },
  dataType: "html",
  cache: false,
      success: function(data) {
  }
});
