So this problem doesn't make sense to me at all because this code worked flawlessly a few months back when i wrote it. I even made a commit with the message "Photo upload works". Still, I opened it up last night and couldn't get it to work for the life of me.
The error that I keep getting is "Request failed: unacceptable content-type: text/html"
This makes no sense as I am setting the content-type to image/jpeg!!!! If anyone has any helpful hints to why this would just stop working i would GREATLY appreciate :) :) :). The code is below.
```
- (void)postPhoto:(NSData *)ImageToPost forImageUUID:(NSString *)photoUUID {
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:#"http://MyURL"]];
[manager setRequestSerializer:[AFHTTPRequestSerializer serializer]];
[manager.requestSerializer setAuthorizationHeaderFieldWithUsername:#"michael" password:#"asdf"];
[manager.requestSerializer setValue:#"image/jpeg" forHTTPHeaderField:#"Content-Type"];
NSDictionary *parameters = #{#"name" : #"MyName", #"photo_uid" : photoUUID};
AFHTTPRequestOperation *op = [manager POST:#"/api/photo/" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
NSString *fileName = [NSString stringWithFormat:#"Photo_%#.jpg",photoUUID];
[formData appendPartWithFileData:ImageToPost name:#"image" fileName:fileName mimeType:#"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success: %# ***** %#", operation.responseString, responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %# ***** %#", operation.responseString, error);
}];
[op setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
NSLog(#"%f%% Uploaded", round(((float)totalBytesWritten / (float)totalBytesExpectedToWrite) * 100));
}];
[op start];
}
```
In the end, the photo gets uploaded 100% but then that error kicks off saying its the wrong content-type and the photo never actually gets posted to my server.
Please help :(
What changed was that the server changed its response format for that endpoint. The error message is that the response from the server is HTML, not JSON as expected by the response serializer.

I have string objects and image stored in nsdata. How can i send it to a server by accessing the url? I have seen examples .but its not working.Can someone tell me
Thanks in Advance!!
You could use AFNetworking to easily send string and image to server using url.
Here is a link of tutorial how to use AFNetworking framework.
AFNetworking Tutorial
AFNetworking is the best way to do that. and there are so much tutorials out there.
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *params = #{#"username": _username.text,
#"password": passwordMD5
};
[manager POST:#"http://example.com/ws/test.php" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject); //This is the Response
}else{
//if you didnt get expected output then handle it here
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
//Handle any network errors here. ex: if internet disconnected.
}];
Here is an example how to upload an image with string objects as a dictionary to a server using AFNetworking.
- (void)uploadPhoto {
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:#"http://server.url"]];
NSData *imageData = UIImageJPEGRepresentation(self.avatarView.image, 0.5);
NSDictionary *parameters = #{#"username": self.username, #"password" : self.password};
AFHTTPRequestOperation *op = [manager POST:#"rest.of.url" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
//do not put image inside parameters dictionary as I did, but append it!
[formData appendPartWithFileData:imageData name:paramNameForImage fileName:#"photo.jpg" mimeType:#"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success: %# ***** %#", operation.responseString, responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %# ***** %#", operation.responseString, error);
}];
[op start];
}
I am posting a JPEG image with some textual data to my server using AFNetworking:
- (NSArray *)postPhoto:(NSData *)jpegData withRoomType:(NSString *)roomType andDescription:(NSString *)description {
dispatch_semaphore_t semaphore = dispatch_semaphore_create(0);
dispatch_queue_t queue = dispatch_get_global_queue(QOS_CLASS_USER_INTERACTIVE, 0);
__block NSArray *returnedMetaData;
AFHTTPRequestOperation *operation = [self.requestManager POST:[Constants postPhotoURLString] parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
NSLog(#"Room: %#", roomType);
[formData appendPartWithFormData:[roomType dataUsingEncoding:NSUTF8StringEncoding]
name:#"room"];
NSLog(#"Description: %#", description);
[formData appendPartWithFormData:[description dataUsingEncoding:NSUTF8StringEncoding]
name:#"description"];
[formData appendPartWithFileData:jpegData
name:#"image"
fileName:#"photo.jpg"
mimeType:#"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
returnedMetaData = (NSArray *)responseObject;
dispatch_semaphore_signal(semaphore);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"%#", error.description);
dispatch_semaphore_signal(semaphore);
}];
operation.completionQueue = queue;
[operation setUploadProgressBlock:^(NSUInteger __unused bytesWritten,
long long totalBytesWritten,
long long totalBytesExpectedToWrite) {
NSLog(#"Wrote %lld/%lld", totalBytesWritten, totalBytesExpectedToWrite);
}];
[operation start];
dispatch_semaphore_wait(semaphore, DISPATCH_TIME_FOREVER);
return returnedMetaData;
}
Every request results in a timeout after 60 seconds:
Error Domain=NSURLErrorDomain Code=-1001 "Time-out van het verzoek." UserInfo=0x15d28d30
Judging from Wireshark, the POST request never even leaves the simulator, and Xcode indicates bandwidth usage is 0. Some other POST requests in my app work fine. Doing the exact same thing in curl as in the code above also works just fine.
Also I checked the URL and no trailing slashes are missing, whatsoever. Copy-pasting the URL to curl and doing a multipart/form-data request does produce the desired outcome.
Am I missing something here?
Thanks!
NSData *imageData = UIImageJPEGRepresentation(YOURIMAGE, 0.5);
NSDictionary * dicParamsToSend = #{#"room" : room,
#"description" : description };
AFHTTPRequestOperation *op = [manager POST:#"rest.of.url" parameters:dicParamsToSend constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
//do not put image inside parameters dictionary as I did, but append it!
[formData appendPartWithFileData:imageData name:#"image" fileName:#"photo.jpg" mimeType:#"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success: %# <=> %#", operation.responseString, responseObject);
}failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %# <=> %#", operation.responseString, error);
}];
[op start];
This might helps you :)
I am totally new to iOS.I want to upload images to my server using AFNetworking.
I tried it but it still not done. Please Help me, thanks in advance
try with this its work for me
-(void) uplodeImages{
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:#"url where to upload images"]];
NSData *imageData = UIImagePNGRepresentation([UIImage imageNamed:#"cat1.png"]);
NSDictionary *parameters = #{#"username": #"", #"password" : #""};
AFHTTPRequestOperation *op = [manager POST:#"cat1.png" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
//do not put image inside parameters dictionary as I did, but append it!
[formData appendPartWithFileData:imageData name:#"userfile" fileName:#"cat1.png" mimeType:#"image/png"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success: %# ***** %#", operation.responseString, responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %# ***** %#", operation.responseString, error);

I am trying to upload a picture from an iPhone to a Django Web Service and I keep getting a 400 with this specific message :
error: {"image": ["No file was submitted. Check the encoding type on the form."]}.
I have sat up for hours trying to figure this out and i believe that somehow, the mime-type is not being sent properly.
Would you have any ideas, or better ways to upload an image than my code below :
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:#"http://MYADDRESS"]];
[manager setRequestSerializer:[AFHTTPRequestSerializer serializer]];
[manager.requestSerializer setAuthorizationHeaderFieldWithUsername:#"user" password:#"pass"];
NSData *imageData = UIImageJPEGRepresentation(image, 1);
NSDictionary *parameters = #{#"image" : imageData, #"name" : #"MyImage" , #"Content-Type" : #"image/jpeg"};
AFHTTPRequestOperation *op = [manager POST:#"/api/photo/" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData name:#"MyImage" fileName:#"MyImage.jpg" mimeType:#"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success: %# ***** %#", operation.responseString, responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %# ***** %#", operation.responseString, error);
}];
[op setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
NSLog(#"%f%% Uploaded", round(((float)totalBytesWritten / (float)totalBytesExpectedToWrite) * 100.));
}];
[op start];
I am downloading jpeg images via POST request using AFNetworking 2.0:
[manager.httpManager.requestSerializer setValue:#"image/jpeg" forHTTPHeaderField:#"Accept"];
NSDictionary *parameters = #{#"filename": imageName};
manager.httpManager.responseSerializer = [AFImageResponseSerializer serializer];
AFHTTPRequestOperation *operation = [manager.httpManager POST:URL_BASE_IMG parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Image: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
Showing the responseObject is not an issue. However, how can I specify a path so that the response object is downloaded straight into it? I have seen the use of streams but I do not know how to implement it here. Anybody? Thanks in advance
