Jquery .ajax method =“post”但$_POST为空

解决JQuery AJAX方法中$_POST为空的问题

javascript
$.ajax({
  type: "POST",
  url: "your_endpoint",
  data: yourData,
  contentType: "application/x-www-form-urlencoded", // 确保Content-Type正确设置
  success: function(response) {
    // 处理成功的响应
  },
  error: function(error) {
    // 处理错误
  }
});

javascript
var yourData = { key1: "value1", key2: "value2" };
$.ajax({
  type: "POST",
  url: "your_endpoint",
  data: $.param(yourData), // 使用$.param方法序列化数据
  success: function(response) {
    // 处理成功的响应
  },
  error: function(error) {
    // 处理错误
  }
});

javascript
var formData = new FormData();
formData.append('key1', 'value1');
formData.append('key2', 'value2');
$.ajax({
  type: "POST",
  url: "your_endpoint",
  data: formData,
  contentType: false,
  processData: false,
  success: function(response) {
    // 处理成功的响应
  },
  error: function(error) {
    // 处理错误
  }
});
