PHP CURL多部分表单数据使用上载问题

我试图上传图像到Api网站，但网站回答没有上传图像。我测试了所有代码，但没有结果。请帮助我

这是我的脚本代码：

            $BOUNDARY = $this->randomPassword();
            $BODY="";
            $BODY .= '------WebKitFormBoundary'.$BOUNDARY. $eol;
            $BODY .= 'Content-Disposition: form-data; name="flowChunkNumber"' . $eol . $eol;
            $BODY .= "1" . $eol;
            $BODY .= '------WebKitFormBoundary'.$BOUNDARY. $eol;
            $BODY .= 'Content-Disposition: form-data; name="flowChunkSize"' . $eol . $eol;
            $BODY .= "15728640" . $eol;
            $BODY .= '------WebKitFormBoundary'.$BOUNDARY. $eol;
            $BODY .= 'Content-Disposition: form-data; name="flowCurrentChunkSize"' . $eol . $eol;
            $BODY .= "2382085" . $eol;      
            $BODY .= '------WebKitFormBoundary'.$BOUNDARY. $eol;
            $BODY .= 'Content-Disposition: form-data; name="flowTotalSize"' . $eol . $eol;
            $BODY .= "2382085" . $eol;      
            $BODY .= '------WebKitFormBoundary'.$BOUNDARY. $eol;
            $BODY .= 'Content-Disposition: form-data; name="flowIdentifier"' . $eol . $eol;
            $BODY .= "2382085-111jpg" . $eol;       
            $BODY .= '------WebKitFormBoundary'.$BOUNDARY. $eol;
            $BODY .= 'Content-Disposition: form-data; name="flowFilename"' . $eol . $eol;
            $BODY .= "111.jpg" . $eol;          
            $BODY .= '------WebKitFormBoundary'.$BOUNDARY. $eol;
            $BODY .= 'Content-Disposition: form-data; name="flowRelativePath"' . $eol . $eol;
            $BODY .= "111.jpg" . $eol;  
            $BODY .= '------WebKitFormBoundary'.$BOUNDARY. $eol;
            $BODY .= 'Content-Disposition: form-data; name="flowTotalChunks"' . $eol . $eol;
            $BODY .= "1" . $eol;        
            $BODY .= '------WebKitFormBoundary'.$BOUNDARY. $eol;
            $BODY .= 'Content-Disposition: form-data; name="flowTotalChunks"' . $eol . $eol;
            $BODY .= "1" . $eol;    
            $BODY .= '------WebKitFormBoundary'.$BOUNDARY. $eol;
            $BODY .= 'Content-Disposition: form-data; name="file"; filename="111.jpg"'. $eol ;
            $BODY .= 'Content-Type: image/jpeg' . $eol . $eol;
            //$BODY.= 'Content-Transfer-Encoding: base64' . $eol . $eol;
            $BODY .= chunk_split(file_get_contents("111.jpg")) . $eol;
            $BODY .= '------WebKitFormBoundary'.$BOUNDARY. $eol;
