I need to send all my forms on server, firstly text forms and then images. Do someone working with it?
The documentation page of AFNetworking shows the following example:
Multi-Part Request
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = #{#"foo": #"bar"};
NSURL *filePath = [NSURL fileURLWithPath:#"file://path/to/image.png"];
[manager POST:#"http://example.com/resources.json" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileURL:filePath name:#"image" error:nil];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];

Using AFNetworking for communication between REST API and my application I ran into a strange behaviour wenn trying to upload an image with PATCH request.
I use following code:
- (void) uploadImage: (UIImage *)image {
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = #{};
AFHTTPRequestSerializer *requestSerializer = [manager requestSerializer];
NSError *e = nil;
NSMutableURLRequest *request = [requestSerializer multipartFormRequestWithMethod:#"PATCH"
URLString:requestString
parameters:parameters
constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:UIImagePNGRepresentation(image)
name:#"image"
fileName:#"image.png"
mimeType:#"image/png"];
} error:&e];
[manager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog("OK");
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog("FAILED");
}];
}
Neither success not failed block of operation will be reached.
Wenn I change the request method to POST everything works fine, but the Server accepts only PATCH method for this case.
Am I doing something wrong?
I finally found a solution for my question:
- (void)uploadImage:(UIImage *)image
withSuccess:(SomeSuccessBlock)success
failure:(SomeFailureBlock)failure {
NSString *requestString = "Some url";
NSError *e = nil;
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
AFHTTPRequestSerializer *requestSerializer = [manager requestSerializer];
NSMutableURLRequest *request = [requestSerializer multipartFormRequestWithMethod:#"POST" URLString:requestString parameters:#{}
constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:UIImagePNGRepresentation(image)
name:#"user[avatar]"
fileName:#"avatar.png"
mimeType:#"image/png"];
} error:&e];
if (e && failure) {
failure(e);
return;
}
[request setHTTPMethod:#"PATCH"];
[request setValue:#"PATCH" forHTTPHeaderField:#"X-HTTP-Method-Override"];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
if (success) {
success();
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
if (failure) {
failure(error);
}
}];
[operation start];
}
I'm sending a POST request:
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
NSDictionary *parameters = #{#"method": #"login", #"email":#"email", #"password":#"password"};
[manager POST:#"http://www.apiwebsite.com" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
My responseObject is:
JSON: <0d0a7b22 72657370 6f6e7365 223a224f 4b222c22 30223a22 6d61696c
696e675f 6b657922 2c223122 3a226239 65653766 34643238 64333730
30666663 37393734 65376665 66626663 3136227d>
But calling the api with POSTMAN i get:
{"response":"OK", "id":"1234223123"}
How can I get the plain or JSON response to work with it?
thanks!
To get JSON object use proper serializer AFJSONResponseSerializer instead of AFHTTPResponseSerializer you uses now.
For debug purpose convert NSData to NSString
NSLog(#"JSON: %#", [[NSString alloc] initWithData: responseObject encoding:NSUTF8StringEncoding]);
I'm trying to have my app load an HTML web page into a "responseObject" that I can later parse.
Here is my code:
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"application/xhtml+xml"];
NSDictionary *parameters = #{#"ghinno": #"1151213"};
[manager GET:#"http://m.ghin.com/HLR.aspx" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"HTTP: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
...and this is the output. I should be seeing the html from the webpage. Can you help me understand what I am doing wrong?
Ah, the answer lies below...
Essentially, it was an encoding / decoding of the response object that was causing my issues. Here is the final solution: (notice the line beginning with "NSString)...
NSURL *URL = [NSURL URLWithString:#"http://m.ghin.com/HLR.aspx?ghinno=1151213"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(#"%#", string);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
[op start];
I tried to make GET HTTP response. I need to get the html code for the subsequent parsing, but responseObject is nil.
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"text/html"];
[manager GET:#"http://www.example.com/" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSError *error;
HTMLParser *parser = [[HTMLParser alloc] initWithString:responseObject error:&error];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
For get html code we will need to build a custom response serializer to decode the NSData response from the web server into a NSString. We will need to subclass AFHTTPResponseSerializer and implement the following method:
- (id)responseObjectForResponse:(NSURLResponse *)response
data:(NSData *)data
error:(NSError *__autoreleasing *)error
{
return [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
}
Why for example you have not use this solution below instead of subcalssing. It does the same thing, but you don't need to create additional files, just for overload one method.
So you can just add encoding your responseObjet in the block for example, and it will work as well. I am using POST in my example but it should work with GET in the same way but without parameters, but idea of the just conversation.
+ (void)makeRequestWithParams:(NSDictionary *)params
success:(OperationCompletionBlock)success
failure:(OperationCompletionBlock)failure
{
NSString *path = #"http://www.example.com/";
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFCompoundResponseSerializer serializer];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"text/html"];
[manager POST:path parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString* encodedString = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(#"%#", encodedString);
success(nil);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
failure(nil);
}];
}
I am using cocoapods to install AFNetworking and AFOAuth2Client. The issue is that it can't import a header file, AFJSONREquestOperation. I have no idea where this dependency lies. Is it another pod or extension to AFNetworking?
It depends of you installed AFNetworking 2.x version, but AFOAuth2 used 1.x version (the latest 1.x is 1.3.3)
If you used Cocoapods, just write in pod file
pod 'AFNetworking', '1.3.3' and than run "pod install"
#LIAL's answer is correct -- as of right now, AFOAuth2Client is not compatible with AFNetworking 2.0. There is an open pull request https://github.com/AFNetworking/AFOAuth2Client/pull/55 that is supposed to make AFOAuth2Client work with AFNetworking 2.0.
You could fork the repo of mlwelles or use https://github.com/mlwelles/AFOAuth2Client.git by modifying your Podfile for AFOAuth2Client line to look like this:
pod 'AFOAuth2Client', :git => 'git://github.com/mlwelles/AFOAuth2Client.git'
Try importing it like this:
#import <AFNetworking/AFJSONRequestOperation.h>
If you can't that way, please make sure you are using Xcode 5. Happened to me when using Xcode 4.6.3.
AFHTTPRequestOperationManager Based Code
AFNetworking 2.x
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:#"http://example.com/resources.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
AFNetworking 3.x
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager GET:#"http://example.com/resources.json" parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
AFHTTPRequestOperation Based Code
AFNetworking 2.x
NSURL *URL = [NSURL URLWithString:#"http://example.com/resources/123.json"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
op.responseSerializer = [AFJSONResponseSerializer serializer];
[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
[[NSOperationQueue mainQueue] addOperation:op];
AFNetworking 3.x
NSURL *URL = [NSURL URLWithString:#"http://example.com/resources/123.json"];
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager GET:URL.absoluteString parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
This answer it's helpful for both user who have use AFNetworking 2.x & 3.x
Thanks.
