问题描述
我一直在努力将UIImage上传到网络服务器。问题是，图像永远不会出现在服务器上。来自HTML文件的普通POST有效。我认为这是我的Objective-c代码中的问题。
I've been working on uploading an UIImage to an webserver. The problem is, that the image never appears on the Server. A normal POST from an HTML file works. I think it's an issue in my objective-c code.
这是我的目标-c代码：
Here is my objective-c code:
NSData *imageData = UIImagePNGRepresentation(delegate.dataBean.image);
NSString *urlString = [NSString stringWithFormat:@"%@test.php", delegate.dataBean.hosterURL];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"rn--%@rn",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"uploadedfile\"; filename=\"test.png\"rn"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-streamrnrn"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:@"rn--%@--rn",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog([NSString stringWithFormat:@"Image Return String: %@", returnString]);
这是我的PHP代码：
<?php
$uploaddir = 'uploads/';
$file = basename($_FILES['uploadedfile']['name']);
$uploadfile = $uploaddir . $file;
echo "file=".$file; //is empty, but shouldn't
if (move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $uploadfile)) {
echo $file;
}
else {
echo "error";
}
?>
推荐答案
现在我自己解决了这个问题=）
Now i've solved it by myself =)
我忘记了身体的反斜杠。
I forgot the backslashes in the body.
这是正确的身体：
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"uploadedfile\"; filename=\"test.png\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];
