我一直在努力将UIImage上传到Web服务器。问题是图片从来没有出现在服务器上。一个普通的HTML文件POST请求可以正常工作,我认为这是我的Objective-C代码的问题。
这是我的Objective-C代码:
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";
}
?>
