I want to send an email address(will be getting from textfield) to http url by clicking a send button from an application which is already logged in at the same http server.
How can I do that programmatically?
u can do this with ASIHTTPRequest library. here is a sample code
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setPostValue:#"Ben" forKey:#"first_name"];
[request setPostValue:#"Copsey" forKey:#"last_name"];
[request setFile:#"/Users/ben/Desktop/ben.jpg" forKey:#"photo"];

I am caching some data using ASIDownloadCache as shown below.
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDownloadCache:[ASIDownloadCache sharedCache]];
[request setCacheStoragePolicy:ASICachePermanentlyCacheStoragePolicy];
[request setCachePolicy:ASIOnlyLoadIfNotCachedCachePolicy];
[request setSecondsToCache:60*60*24*30]; // Cache for 30 days, this will change to a db version check.
[request setDelegate:self]; // this calls the delegate function requestFinished
[request startAsynchronous];
I was wondering how secure that data was? for instance I know that someone with a jailbroken phone can access coredata sotrage.. but what about ASIDownloadCache? what would someone need to do to get to it? how can I protect it?
You don't even have to jailbreak to access it, see:
http://www.macroplant.com/iexplorer/
If you want to protect it, you'll need to encrypt it, and you will have to do this yourself or modify ASIDownloadCache to do it.
Given the decryption key will need to be present in your application this would really just be obfuscation though.
How to use post manner to transmit username and password in order to log in a website on iphone or ipad platform?
Some one has suggest me that use ASIHTTPRequest,but I don't know how to use it．
Can somebody help me ?Thank you ........
ASIHTTPRequest has one of the best how to use pages of any library I have ever encountered. It is located here: http://allseeing-i.com/ASIHTTPRequest/How-to-use
If you need to post to a web form you could do something like this:
#define kURLString #"https://yourwebsite.com"
NSURL *url = [NSURL urlWithString:kURLString];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setPostValue:#"myname" forKey:#"username"];
[request setPostValue:#"l33td00d" forKey:#"password"];
[request setDelegate:self];
[request startSynchronous];
Although in real life you may wish to run the request asynchronous. The details on how to do that are on the page I linked. It is defiantly worth reading.
I'm developing an iPhone application using the Facebook Connect API. I arrived to set the "Like" on a post using the following code:
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"https://graph.facebook.com/%#/likes", discussion.postId]];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setPostValue:[self.facebook accessToken] forKey:#"access_token"];
[request setDelegate:self];
[request startAsynchronous];
It generates the following call:
HTTP POST https://graph.facebook.com/147512198609691_148877991806445/likes
But I'm not able to do the inverse operation "Unlike" (removing the like
from the post).
I tried the following:
HTTP POST https://graph.facebook.com/147512198609691_148877991806445/likes?access_token=....&method=delete
and also:
HTTP DELETE https://graph.facebook.com/147512198609691_148877991806445/likes?access_token=....
But those are not working, probably I'm using a wrong command.
[request setPostValue:#"DELETE" forKey:#"method"];
I am a backend Rails developer of an API that services several iPhone clients. I'm not an iPhone dev.
I have a need to accept binary data (several image files in this case) from the client via a POST request to the API.
To get the file content (file metadata other than image type is not relevant here), what tools might be used by the iPhone developer? I've found ObjectiveResource (used by iPhone on Rails) and ASIHTTPRequest. In the pages I found for those, there's no indication of what form the uploaded file will have when the controller action is executed. Will it be a Ruby File object or Tempfile object? I don't control the iPhone code development, there are some cross-cultural communication difficulties there, and they haven't used those suggestions so far. If I can submit better information to them, I might be getting better data back.
The backend app is currently running Rails 2.3.10, and will soon (in the next few weeks) likely be converted into Rails 3.
Thanks,
Craig
ObjectiveResource does not natively support file uploads. Try instead using ASIHTTPRequest with this snippet:
NSURL *url = [NSURL URLWithString:#"http://localhost:3000/file"];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setPostValue:#"Sample" forKey:#"name"];
[request setFile:... forKey:#"file"];
[request startSynchronous];
For more details, see the example page here (sending data).
The post will be encoded as a standard multipart form post (just like if it came from an HTML form). If you are using paperclip to store your uploads, the magic will just happen!
Use JSON over HTTP
NSMutableURLRequest *request =
[[NSMutableURLRequest alloc] initWithURL: [NSURL URLWithString:urlStr]];
[request setHTTPMethod: #"POST"];
[request setValue:#"application/json; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
NSString* requestDataLengthString = [[NSString alloc] initWithFormat:#"%d", [jsonMessageStr length]];
[request setValue:requestDataLengthString forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setHTTPBody:jsonData];
NSURLConnection *theConnection =
[[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES];
I'm trying to make a log in or sign up feature for my web site in my iPhone app. My website is a content management system, and like any other CMS, it has log in and registration features. It also has permmissions, dependent on the user account. I think I would have to use UIWebView for this.
Are there any examples or tutorials I can examine?
Check out the documentation for NSURLRequest (and NSMutableURLRequest): you can use it to make a POST request to your login and registration pages, just like a web browser. You can write the form UI in Cocoa/Objective-C and then send the data to the server.
As far as displaying the result to the user, you'll have to figure out a way to either parse the returned HTML (bad idea) or modify your CMS to return JSON or XML to iPhone requests (better idea).
Edit: Here's some sample code, taken from an app I'm working on (it submits data to Last.fm using POST):
NSURL *url = [NSURL URLWithString:#"http://example.com/"];
NSString *str = #"This is my example data!";
// everything below here is directly from my app:
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:[str dataUsingEncoding:NSUTF8StringEncoding]];
[request setValue:kLastFMClientUserAgent forHTTPHeaderField:#"User-Agent"];
[request setCachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData];
[request setHTTPShouldHandleCookies:NO];
*connection = [[NSURLConnection alloc] initWithRequest:request
delegate:self
startImmediately:YES];
