forge 大文件上传, 返回504。

Question

问题描述

forge-node-api
uploadchunk() 返回504

问题出现的环境背景及自己尝试过哪些方法

我试图通过 在aws s3上获取一个（380M）已经存在的obj模型，然后使用forge-node-api上传到forge s3。 开始我使用
ObjectsApi().uploadObject() 这个方式进行上传。

RangeError: Array buffer allocation failed

查看文档发现
Note that for objects larger than 100 MB we recommend using the[PUT buckets/:bucketKey/objects/:objectName/resumable]endpoint.

对应到forge-node-api中

   /**
     * This endpoint allows resumable uploads for large files in chunks.
     */
    uploadChunk(
        bucketKey: string,
        objectName: string,
        contentLength: number,
        contentRange: string,
        sessionId: string,
        body: string | Buffer,
        opts: { contentDisposition?: string; ifMatch?: string },
        oauth2Client: AuthClient,
        credentials: AuthToken,
    ): Promise<ApiResponse>;

相关代码

async function uploadToAutdeskForgeChunk(key,contentLength,buffer) {
    console.log('start upload autodesk forge chunk ');
    const bucketKey = "7tzrrgdkveypaae9rm7ba6xm9sujgplb-testbuckey123";
    let chunkSize = 5*1024*1024;
    let chunkNumber = buffer.length / chunkSize;
    chunkNumber =  Math.round(0.5 + chunkNumber);
    let promises = [];
    let token = await getInternalToken();
    for(let i = 0; i < chunkNumber; i++) {   
        let start = i * chunkSize;
        let end = Math.min(buffer.length, (i + 1)*chunkSize) - 1;
        let range = "bytes " + start + "-" + end + "/" + buffer.length;
        let chunklength = end - start + 1;
        let sessionID = "64546463132131" + i;  //测试用
        console.log(range);
        let chunk = buffer.slice(start, end);
        console.log(chunk.length)
        // promises.push(new ObjectsApi().uploadChunk(bucketKey, key, chunklength, range, sessionID, buffer.slice(start, end), {}, getClient(),  token ))
        new ObjectsApi().uploadChunk(bucketKey, key, chunklength, range, sessionID, chunk, {}, getClient(),  token ).then( (res) => {
            console.log(res);
        }).catch( (err) => {console.log(err)})
    }
    // return Promise.all(promises)
}

实际看到的错误信息又是什么？

{ statusCode: 504, statusMessage: 'GATEWAY_TIMEOUT', statusBody: '' }

sometime：

Error: ESOCKETTIMEDOUT
    at ClientRequest.<anonymous> (/home/ec2-user/forge_demo/node_modules/request/request.js:816:19)
    at Object.onceWrapper (events.js:421:28)
    at ClientRequest.emit (events.js:315:20)

    at listOnTimeout (internal/timers.js:549:17) {

}

从status code来看应该是服务端出问题了，但是不太确定，到底是哪出的问题。
