问题描述
我使用
它使用在现代浏览器中的XHR文件上传和oldIE中的隐藏iframe上传(8,9)。
It uses XHR file uploads in modern browser and hidden iframe uploads in oldIEs (8,9).
当文件验证失败时,服务器返回4xx状态代码(错误/失败)。
The server returns a 4xx status code (error/fail), when file validation failed.
$('#fileupload').fileupload({
url: url,
dataType: 'json',
done: function (e, data) {
console.log("done")
},
fail: function (e, data) {
console.log("fail")
}
})
但是在oldIE中,即使我发送4xx状态码,也会调用done回调。
是否有一种方法可以调用失败回调()并读取响应正文或状态码?
However in oldIEs the done callback is called even when I send a 4xx status code.Is there a way to make it call the fail callback (https://github.com/blueimp/jQuery-File-Upload/wiki/Options#fail) and read the response body or statuscode?
我认为它可能需要做一些与隐藏的iframe方法上传的文件,但我找不到任何具体的文档。
I think it might have to do something with the hidden iframe method of uploading the files but I couldn't find anything specific in the docs.
推荐答案
我应该检查
// By default, the iFrame Transport handles all responses as success,
// so we override the iFrame to JSON converter to handle error responses:
$.ajaxSetup({
converters: {
'iframe json': function (iframe) {
var result = iframe && $.parseJSON($(iframe[0].body).text());
if (result.error) {
// Handling JSON responses with error property:
// {"error": "Upload failed"}
throw result.error;
}
return result;
}
}
});
