HTTP POST到Imageshack [英] HTTP POST to Imageshack
问题描述
我目前正在通过HTTP POST将图像上传到我的服务器。一切正常使用下面的代码。
I am currently uploading images to my server via HTTP POST. Everything works fine using the code below.
NSString *UDID = md5([UIDevice currentDevice].uniqueIdentifier);
NSString *filename = [NSString stringWithFormat:@"%@-%@", UDID, [NSDate date]];
NSString *urlString = @"http://taptation.com/stationary_data/index.php";
request= [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
NSString *boundary = @"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];
NSMutableData *postbody = [NSMutableData data];
[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@.jpg\"\r\n", filename] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[NSData dataWithData:imageData]];
[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postbody];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(returnString);
但是，当我尝试将其转换为使用Image Shacks XML API时，任何东西。从ImageShack的方向如下。
However, when I try to convert this to work with Image Shacks XML API, it doesn't return anything. The directions from ImageShack are below.
通过POST将以下变量发送到imageshack。 us /index.php
Send the following variables via POST to imageshack. us /index.php
fileupload; （image）
xml =yes; （指定返回XML）
cookie; （注册码，可选）
fileupload; (the image) xml = "yes"; (specifies the return of XML) cookie; (registration code, optional)
有人知道我应该从这里开始吗？
Does anyone know where I should go from here?
推荐答案
您可能需要考虑使用 ASIHTTPRequest ，因为它将为你建立一个表单数据的文章主体，减少了很多麻烦，并且可以从磁盘流式传输请求主体，因此在上传大图片时，可以节省内存。
You might want to consider using ASIHTTPRequest, as it will build a form data post body for you with a lot less hassle, and can stream the request body from disk, so you'll save memory when uploading large images.
Google快速找到这，似乎建议您发布到/upload_api.php而不是/index.php。
A quick google found this, which seems to suggest you should be posting to /upload_api.php rather than /index.php.
这样可能是一个好的开始：
Something like this would probably be a good start:
ASIFormDataRequest *request = [[[ASIFormDataRequest alloc] initWithUrl:[NSURL URLWithString:@"http://www.imageshack.us/upload_api.php"]] autorelease];
[request setFile:@"/path/to/file" forKey:@"fileupload"];
[request setPostValue:@"yes" forKey:@"xml"];
[request setPostValue:@"blahblah" forKey:@"cookie"];
//It looks as though you probably need these too
[request setPostValue:@"me@somewhere.com" forKey:@"email"];
[request setPostValue:@"blah" forKey:@"key"];
[request start];
if ([request error]) {
NSLog(@"%@",[request error]);
} else {
NSLog([request responseString]); // The xml that got sent back
}
警告：未经测试！
我使用了一个同步请求，因为你使用了同步请求，但你几乎肯定应该使用一个异步请求（使用ASIHTTPRequest的队列）。
I've used a synchronous request because you did, but you almost certainly should be using an asynchronous request instead (a queue with ASIHTTPRequest).
