我正在尝试使用HTPP POST方法上传多个图像。但不知何故它不起作用。我每次上传3张图片,但只上传了1张图片。
以下是代码:
- (void)sendImageUploadRequest:(NSMutableArray *)arrImage
{
if(arrImage)
{
NSString *strUrl = [NSString stringWithFormat:@"upload.php"];
NSString *urlString = [NSString stringWithFormat:ServerURL,strUrl];
NSString *method = @"POST";
NSString *email = @"xyz@gmail.com";
// NSString *token = @"";
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
NSMutableData *body = [NSMutableData data];
NSString *boundary;
boundary = [NSString stringWithFormat:@"---------------------------14737809831466499882746641449"];
// file
for (int i = 0; i < [arrImagesUpload count]; i++) {
NSData *imageData = UIImageJPEGRepresentation([arrImagesUpload objectAtIndex:i], 0.8);
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
NSString *strNameImage = [NSString stringWithFormat:@"test%d.jpg", i];
NSString *str = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"images[]\"; filename=\"%@\"\r\n", strNameImage];
[body appendData:[str dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
}
// parameter username
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"email\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[email dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
// // parameter method
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"method\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[method dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
// close form
[body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust
[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);
}
}
任何人都可以帮我解决问题。
