嗨,我正在尝试使用以下代码将任意文件与ASP.NET Core Server上传到我的ASP.NET Core Server:
$.ajax({
url: '/Provider/Image/' + guid,
type: "POST",
contentType: false, // Not to set any content header
processData: false, // Not to process data
data: image,
success: function (result) {
alert(result);
},
error: function (err) {
alert(err.statusText);
}
});
映像是从类型"文件"
输入的表单中我的C#是:
[ActionName("Image")]
[HttpPost]
[Authorize]
public async Task<IActionResult> UploadImage(List<IFormFile> files, Guid id)
{
var file = Request.Form.Files[0];
问题是"文件"是空的,"文件"给了我错误"不正确的内容类型:image/png"
stacktrace [string]:"在Microsoft.aspnetcore.http.features.formfeature.readform() r n on microsoft.aspnetcore.http.internal.defaulthttprequest.get_get_get_get_form()
我曾经遇到过这个问题,我的解决方案是将上传机构绑定到ViewModel。这样,我就可以使用其他参数将文件上传到服务器(在您的情况下,您将传递给URL)。为此,我首先创建了一个视图模型
public class UploadImageViewModel
{
public IFormFile file {get;set;}
public Guid uniqueId {get;set;}
}
并在我的控制器中使用了
public async Task<IActionResult> UploadImage(UploadImageViewModel model)
{
//Here I can access my file and my Guid
var file = model.file;
Guid id = model.uniqueId;
}
在我的jQuery调用中,我通过了一个模型,而不是单个(或多个)文件:
var dataModel = new FormData();
dataModel.append('file', document.getElementById("YOUR-FILEUPLOAD-FIELD-ID").files[0]);
dataModel.append('uniqueId', guid);
$.ajax({
url: '/Provider/Image/' + guid,
type: "POST",
contentType: false, // Not to set any content header
processData: false, // Not to process data
data: image,
success: function (result) {
alert(result);
},
error: function (err) {
alert(err.statusText);
}
});
