问题描述
限时送ChatGPT账号..我不知道为什么我无法让 jQuery 传递上传数据,因为 AJAX 对象似乎配置正确,并且正在发送正确的 Content-Type/MIME-Type 标头.
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.
我尝试了两种不同的请求形式——一种是将 FormData 对象包含在文字中,另一种是直接传递 FormData 对象.
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,无论哪种方式我都无法通过,$_FILES 和 $_POST 都是空数组.
Unfortunately either way I can't get anything to pass, and both $_FILES and $_POST are empty arrays.
我希望使用的理想请求如下:
The ideal request I wish to use is as follows:
连同以下代码:
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,当我尝试导出 $_FILES 和 $_POST 时,唯一的响应(同时查看网络选项卡和控制台)只是两个空数组...
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
你必须传递FormData
对象作为数据参数
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'); }
});
