尝试使用tus上传到vimeo时遇到"Content length 0 too small“问题

Question

我正在尝试使用他们的可恢复上传协议将视频文件上传到vimeo，但最终得到

Failed because: Error: tus: unexpected response while creating upload, originated from request (method: POST, url: https://1515143405.cloud.vimeo.com/upload?ticket_id=42606237…62378%26signature%3D19062b29129850403638ca88040debe1e21cc646, response code: 400, response text: Content length 0 too small

每次我开始上传的时候都会出现这个错误。

const vimeoFileUpload = async(e) => {
const fileContent = e.target.files[0];
const fileSize = fileContent.size;
const reader = new FileReader();
reader.onload = r => {console.log(r.target.result)};
let uploadLink;

await fetch(`${backendUri}/fetchUploadLink`, {
    method: 'POST',
    body: JSON.stringify({fileSize}),
    headers: {"Content-Type": "application/json"}
}).then((res) => res.json())
   .then((result) => {
       uploadLink=result.uploadLink
   });

let uploader = new tus.Upload(fileContent, {
    uploadUrl: uploadLink,
    endpoint:uploadLink,
    retryDelays: [0, 1000, 3000, 5000],
    metadata: {
        filename: "sample",
        filetype: fileContent.type
    },
    uploadSize: fileSize,
    onError: function(error) {
        console.log("Failed because: " + error);
    },
    onProgress: function(bytesUploaded, bytesTotal) {
        let percentage = (bytesUploaded / bytesTotal * 100).toFixed(2);
        console.log(bytesUploaded, bytesTotal, percentage + "%");
    },
    onSuccess: function() {
        console.log(
            "Download %s from %s",
            uploader.file.name,
            uploader.url
        );
    }
});
uploader.start();
}

这是upload函数的代码。我还尝试将Content-Length设置为tus配置中的自定义标头，但它声称这是一个禁止的标头，不让我修改它

对这件事的任何想法或建议都将非常感谢。

创建视频的初始请求很可能是错误的或无效的。对于tus上传，Vimeo API将在files.tus.vimeo.com域(或类似域)上返回一个upload_link。确保初始POST /me/videos请求指定upload.approach=tus。

在尝试实际的文件上传之前，您需要验证API是否返回upload.approach=tus。

Vimeo API的tus文档可以在这里找到：https://developer.vimeo.com/api/upload/videos#resumable-approach
