我读过很多人有同样的问题，都是相似的，都与我的服务器设置有关，确保图像目录具有 755 权限，并且出于某种原因我看到我的用户子文件夹设置为 777，并且我已经创建了 php.ini 文件，我确保我的upload_max_filesize设置正确， 并且我的 php.ini 具有适当的设置。我从许多不同的教程中尝试了几种不同的编码技术，都输出了相同的错误。
这是我的NSlog中的错误

这是我的目标-c代码
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[self dismissViewControllerAnimated:YES completion:NULL];
NSData *dataImage = UIImageJPEGRepresentation(image.image, 0.8f);
NSString *urlString = @"http://www.myproject.com/myphpscript.php";
NSString *filename = [NSString stringWithFormat:@"%@.jpg", [MyClass str]];
NSMutableURLRequest* request= [[NSMutableURLRequest alloc] init];
[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='"image'"; filename='"%@.png'"'r'n", filename] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[@"Content-Type: application/octet-stream'r'n'r'n" dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[NSData dataWithData:dataImage]];
[postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name='"%@'"'r'n'r'n", @"email"] dataUsingEncoding:NSASCIIStringEncoding]];
[postbody appendData:[[NSString stringWithFormat:@"%@",[MyClass str]] dataUsingEncoding:NSASCIIStringEncoding]];
[postbody appendData:[[NSString stringWithFormat:@"'r'n--%@--'r'n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postbody];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString* returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(@"test %@",returnString);
}
和我的 PHP
<?php
// removed connection
$mysqli = new mysqli($host, $username, $password, $database);
if ($stmt = $mysqli->prepare("INSERT INTO `user` SET imagepath=? WHERE email=?"))
{
$stmt->bind_param('ss', $albumname, $email);
$uploaddir = 'images/users/';
$file = basename($_FILES['userfile']['name']);
$uploadfile = $uploaddir . $file;
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
}
$albumname = $uploadfile;
$email = $_POST['email'];
$stmt->execute();
$stmt->close();
}
else {
printf("Prepared Statement Error: %s'n", $mysqli->error);
}
$mysqli->close();
?>
错误 500 是服务器端的错误。
我建议尝试从服务器上传到自身，这样您就可以获得更多信息。还要检查来自Web服务器，nginx，appache或您运行的任何内容的错误日志，在那里您会发现导致错误的原因。
虽然我无法仅从您的代码中看到 500 错误是什么，但我强烈建议您确保 PHP ini 文件启用了错误日志记录并查看日志文件。 在大多数情况下，500 错误是由 PHP 引擎中的运行时错误引起的，它将输出到日志文件，或者如果您启用了display_errors，则会直接输出到浏览器。
10 次中有 9 次，一旦您可以读取日志文件，错误就很容易修复。
