POObjective-C Box 2.0 File Upload - Problems
text
Body
copied!<p>I've been trying to get file upload working with Box for the past few days. I know I'm doing something wrong, but just can't see what it is.</p> <p>I've reduced my code down as much as I possibly can, to just this:</p> <pre><code>// Configure the request NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; [request setURL:[NSURL URLWithString:@"https://api.box.com/2.0/files/data"]]; [request setHTTPMethod:@"POST"]; [request setValue:boxAuthString forHTTPHeaderField:@"Authorization"]; // Setu up the request NSString *boundary = [NSString stringWithString:@"--PLEASEHELPMEGETTHISWORKING"]; NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@\r\n",boundary]; [request addValue:contentType forHTTPHeaderField: @"Content-Type"]; NSMutableData *body = [NSMutableData data]; // Add the info and data for the file. [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:@"Content-Disposition:form-data;name=\"filename\";filename=\"testfile.txt\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:@"Content-Type:text/plain\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:@"Hello"] dataUsingEncoding:NSUTF8StringEncoding]]; // Add the info and data for the target folder. [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:@"Content-Disposition:form-data;name=\"folder_id\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:@"0"] dataUsingEncoding:NSASCIIStringEncoding]]; // Close the body and set to the request [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n", boundary] dataUsingEncoding: NSUTF8StringEncoding]]; [request setHTTPBody:body]; // now lets make the connection to the web NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; NSLog(@"%@", returnString); </code></pre> <p>But, I still get a return of: {"type":"error","status":404,"code":"not_found","help_url":"http://developers.box.com/docs/#errors","message":"Not Found","request_id":"10130600215xxxxxxxxxxx"}</p> <p>Please can someone help point me in the right direction, as when I use POSTMAN or cURL, I can get it to work - so it is obviously an issue with my code. I suspect it is something to do with the 'folder_id', but can't seem to diagnose the actual cause.</p>
