使用ASIHTTPRequest从iOS上传图像
我的应用上传图像和用户/电子邮件/通过注册。 iOS到PHP到MySQL。 电子邮件，用户和通行证和图像名称保存到数据库就好了。 它只是没有上传到服务器上的文件夹的图像。 所以它只是我的代码，这是失败的一部分，但任何人都可以看到哪里？ 我在我的服务器上有这个代码：

-(void)callASIHTTP{ NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://www.myserver.com/learn/login/user_save2.php"]]; // Upload an NSData instance NSData *imageData = UIImageJPEGRepresentation(self.pickedImage, 90); ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url]; [request addPostValue:self.userName.text forKey:@"username"]; [request addPostValue:self.userPass.text forKey:@"password"]; [request addPostValue:self.userEmail.text forKey:@"email"]; [request addData:imageData withFileName:self.userName.text andContentType:@"image/jpeg" forKey:@"photo"]; //check if passedData is nil if (imageData == nil) { UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"title:iDnil" message:@"msg:iDnil" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alertView show]; [alertView release]; } //completion blocks [request setCompletionBlock:^{ NSString *responseString = [request responseString]; if (responseString == nil) { UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"title:rStrg" message:@"msg:rStrg" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alertView show]; [alertView release]; } }]; [request setFailedBlock:^{ NSError *error = [request error]; NSLog(@"Error: %@", error.localizedDescription); }]; [request startAsynchronous]; }
我知道你的问题..我遇到了同样的问题..你必须给图像的path..下面的代码将从path中获取图像..如果图像是在你的目录索引，你必须得到path有点不同..试试这个，让我知道..
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:@"photo.jpg"]; [request setFile:[NSURL URLWithString:dataPath] forKey:@"photo"]; //IF the photo is in directory index use the following code to get the url NSString *filename = [[NSBundle mainBundle] pathForResource:@"photo" ofType:@"png"]; [request setFile:[NSURL URLWithString:filename] forKey:@"photo"];
好的，这里是你必须为UIImagePicker写的代码
- (void) imagePickerController:(UIImagePickerController *)thePicker didFinishPickingMediaWithInfo:(NSDictionary *)imageInfo { imagePicker = nil; UIImage *image = [imageInfo objectForKey:@"UIImagePickerControllerEditedImage"]; image = [image roundedCornerImage:23.5 borderSize:1]; // Get the data for the image as a JPEG NSData* imageData = UIImageJPEGRepresentation(image, 0.5); // Give a name to the file NSString* imageName = @"photo.png"; // Now, we have to find the documents directory so we can save it // Note that you might want to save it elsewhere, like the cache directory, or something similar. NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString* documentsDirectory = [paths objectAtIndex:0]; // Now we get the full path to the file NSString* fullPathToFile = [documentsDirectory stringByAppendingPathComponent:imageName]; [imageData writeToFile:fullPathToFile atomically:NO]; myPicture = imageData; myPicturePath = fullPathToFile; // Dismissing the image picker view [self dismissModalViewControllerAnimated: YES]; }
上传图片时使用这个代码..你将从图像select器设置myPicturepath..
Request setFile:myPicturePath forKey:@"photo"];
下面的代码是从文档目录中获取图像并发送它..
NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString* documentsDirectory = [paths objectAtIndex:0]; // Now we get the full path to the file NSString* fullPathToFile = [documentsDirectory stringByAppendingPathComponent:@"photo.png"]; [imageData writeToFile:fullPathToFile atomically:NO]; [Request setFile:fullPathToFile forKey:@"photo"];
我知道这是愚蠢的，但我有一个类似的问题，只是发现它是在Web服务器上的文件夹权限。
