当我尝试使用Twitter API发布图像或视频时,我收到错误消息

{“request”:”/i/media/upload.json”,”error”:”Segments do not add up
to provided total file size.”}

Google没有关于此错误的任何信息. Twitter文档也没有帮助.怎么了？

我在做什么：

1. INIT uploading file

> $this->SetUrl('upload.twitter.com/i/media/upload.json?command=INIT&media_type=image%2Fpng&total_bytes='
> . $filesize)
>                 ->SendRequest('post');

2. APPEND chunks

> $reply = ['media' => $chunk];
> $this->SetQuery($reply);
> $this->SetUrl('upload.twitter.com/i/media/upload.json?command=APPEND&media_id='.$mediaId.'&segment_index='.$segment_id)->SendRequest('post');

3. When I FINALIZE,I get the error

> $this->SetUrl('upload.twitter.com/i/media/upload.json?command=FINALIZE&media_id='
> . $mediaId)->SendRequest('post');

解决方法

// APPEND
    $ch = curl_init();
    $file = fopen($media,'r');
    $chunk_id = 0;

    while (!feof($file)) {

        $append_headers = array();
        $chunk = fread($file,1048576); // 1mb per chunk
        $boundary = $chunk_id.time();
        $params  = "--" . $boundary . "rn"
            . "Content-Type: video/mp4rn"
            . "Content-Disposition: form-data; name="media"; filename="blob"rn"
            . "rn"
            . $chunk . "rn"
            . "--" . $boundary . "--";
        $append_headers[] = 'Content-Length: ' . strlen($params);
        $append_headers[] = 'Content-Type: multipart/form-data; boundary=' . $boundary;
        curl_setopt($ch,CURLOPT_HTTPHEADER,$append_headers);
        curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
        curl_setopt($ch,CURLOPT_POST,CURLOPT_POSTFIELDS,$params);
        curl_setopt($ch,CURLOPT_USERAGENT,$this->curl_config['useragent']);
        curl_setopt($ch,CURLOPT_COOKIEJAR,$this->cookie_dir . md5($this->UserName . $this->Password));
        curl_setopt($ch,CURLOPT_COOKIEFILE,CURLOPT_URL,'https://upload.twitter.com/i/media/upload.json?command=APPEND&media_id=' . $init->media_id . '&segment_index=' . $chunk_id);
        $response = curl_exec($ch);
        $chunk_id++;

    }

这是我发布块的解决方案.效果很好.
