获取来自图像选择器的图像
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
Profilebackground.image = chosenImage;
[picker dismissViewControllerAnimated:YES completion:NULL];
NSURL *resourceURL;
UIImage *image =[[UIImage alloc] init];
image =[info objectForKey:@"UIImagePickerControllerOriginalImage"];
NSURL *imagePath = [info objectForKey:@"UIImagePickerControllerReferenceURL"];
imageName = [imagePath lastPathComponent];
resourceURL = [info objectForKey:UIImagePickerControllerReferenceURL];
NSString *extensionOFImage =[imageName substringFromIndex:[imageName rangeOfString:@"."].location+1 ];
if ([extensionOFImage isEqualToString:@"JPG"])
{
imageData =UIImageJPEGRepresentation(image, 1.0);
base64 = [imageData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
extension=@"image/jpeg";
}
else
{
imageData = UIImagePNGRepresentation(image);
base64 = [imageData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
extension=@"image/png";
}
int imageSize=imageData.length/1024;
NSLog(@"imageSize--->%d", imageSize);
if (imageName!=nil) {
NSLog(@"imageName--->%@",imageName);
}
else
{
NSLog(@"no image name found");
}
将图像发送到服务器
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager POST:@"https://blahblahblah.com/uploadProfileImg?userId=1" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
//NSData *pngData = [[NSData alloc] initWithBase64EncodedString:base64 options:1];
[formData appendPartWithFileData:imageData
name:@"key"
fileName:imageName mimeType:extension];
} success:^(NSURLSessionDataTask *task, id responseObject) {
NSLog(@"Response: %@", responseObject);
} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSHTTPURLResponse *response = (NSHTTPURLResponse *)task.response;
NSLog(@"error: %@",error);
// NSHTTPURLResponse *response = (NSHTTPURLResponse *)operation.response;
NSLog(@"statusCode: %ld", (long)response.statusCode);
NSString* ErrorResponse = [[NSString alloc] initWithData:(NSData *)error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey] encoding:NSUTF8StringEncoding];
NSLog(@"Error Response:%@",ErrorResponse);
}];
推荐答案
你可以使用 appendPartWithFileData:name:fileName:mimeType:
AFMultipartFormData
类的方法。
You can just use the appendPartWithFileData:name:fileName:mimeType:
method of the AFMultipartFormData
class.
For实例:
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager POST:@"https://blahblahblah.com/imageupload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData
name:@"key name for the image"
fileName:photoName mimeType:@"image/jpeg"];
} success:^(NSURLSessionDataTask *task, id responseObject) {
NSLog(@"Response: %@", responseObject);
} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSLog(@"Error: %@", error);
}];
