jQuery的AJAX“的multipart / form-data的”不发送数据？

问题描述

我在为什么我不能因为AJAX对象似乎是正确配置的jQuery通过上传数据看到的损失，正确的内容类型/ MIME类型的头被发送。

I'm at a loss for why I can't get jQuery to pass upload data seeing as the AJAX object appears to be configured correctly, and the correct Content-Type/MIME-Type headers are being sent.

我试过两个独立的申请表 - 之一，包含在字面上一个FORMDATA对象，也刚好路过FORMDATA对象直接

I've tried two separate forms of request--one with a FormData object contained within a literal, and also just passing the FormData object directly.

不幸的是无论哪种方式，我不能得到任何通过，既$ _FILES和$ _ POST是空的数组。

Unfortunately either way I can't get anything to pass, and both $_FILES and $_POST are empty arrays.

理想的要求我想使用如下：

The ideal request I wish to use is as follows:

随着下面的code：

var files = new FormData();

$.each(context.prototype.fileData, function(i, obj) { files.append(i, obj.value.files[0]); });

var request = { action: 'upload', id: response.obj.id, data: files };

$.ajax({

    type        : 'POST',
    url         : context.controller,
    data        : request,
    processData : false,
    contentType : 'multipart/form-data',
    mimeType    : 'multipart/form-data',

    success     : function(r) {
        console.log(r);
        //if (errors != null) { } else context.close();

    },

    error       : function(r) { alert('jQuery Error'); }

});

再一次唯一的反应（看着两个网络选项卡和放大器;控制台），当我尝试导出两个$ _FILES和$ _ POST简直就是两个空数组...

Once again the only response (looking at both the Network tab & Console) when I try to export both $_FILES and $_POST is simply two empty arrays...

推荐答案

您必须将 FORMDATA 对象传递的数据参数

You have to pass the FormData object as the data parameter

var request = new FormData();
$.each(context.prototype.fileData, function(i, obj) { request.append(i, obj.value.files[0]); });
request.append('action', 'upload');
request.append('id', response.obj.id);
$.ajax({

    type        : 'POST',
    url     : context.controller,
    data        : request,
    processData : false,
    contentType : false,
    success     : function(r) {
        console.log(r);
        //if (errors != null) { } else context.close();

    },

    error       : function(r) { alert('jQuery Error'); }

});
