我們正試圖使用jQuery ajax &將文件上傳到預先註冊的url。我們在服務器上生成預先註冊的url。目前我們正在嘗試使用FormData來上傳文件。使用JQuery將文件上傳到S3,使用預先登記的URL
var uploadData = new FormData(),
files = $(this.input).prop('files'),
file = files[0];
uploadData.append('file', file);
$.ajax({
url: '{presigned url string}',
type: 'PUT',
data: uploadData,
cache: false,
processData: false,
contentType: false,
success: function(response) {
console.log('S3 upload success!');
},
error: function(response) {
console.log('Error with S3 upload: ' + response.statusText);
}
});
這將返回從AWS一個SignatureDoesNotMatch錯誤:

我知道presigned鏈接的作品,因爲我可以通過捲曲正確上傳的文件:
curl -v --upload-file {filename} {presigned url}
我遇到同樣的問題,但設置內容類型沒有幫助。會喜歡一些幫助! – kungfoo 2015-03-06 13:26:22
該解決方案對我很好,但上傳到S3的文件附帶了FormData值。你知道如何防止這種情況嗎? – schoonie23 2015-10-01 22:03:58
