What would be the reason for getting Invalid Request when we are posting an URL to server in iOS SDK. the URL what i am sending is correct and the data what I'm posting is also correct.
I tried in RestClient also even though I'm getting same error Invalid Request in that also.
Can any one help me what would be the reason for it.
Thanks in advance.

The JSON you are posting might be invalid. Please validate it using this. There should be no character outside the { }.
Just post the following string instead of the current JSON

I tried to 1)POST image to URL and 2)get Image fro URL.
Posting worked :-
-(void)Send:(id)sender
{
NSData *imageData = UIImagePNGRepresentation(myImageView.image);
myString = [Base64 encode:imageData];
NSString *post =[NSString stringWithFormat:#"?&image=%#",
myString];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d",[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init] ;
[request setURL:[NSURL URLWithString:[NSString stringWithFormat:#"http://192.168.3.125:8090/SaveDollar/rest/classifieds/addTestImages"]]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Current-Type"];
[request setHTTPBody:postData];
con3 = [[NSURLConnection alloc]initWithRequest:request delegate:self];
if(con3)
{ webData3=[NSMutableData data];
NSLog(#"Connection successfull");
NSLog(#"GOOD Day My data %#",webData3);
}
else
{
NSLog(#"connection could not be made");
}
}
But When I Get Image for JSON i got error:-
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{if (connection==con2)
{
al=[NSJSONSerialization JSONObjectWithData:webData2 options:0 error:nil];
for (NSDictionary *diction in al)
{
NSString *geting =[diction valueForKey:#"image"];
NSLog(#"geting is %#",geting);
getdata = [NSData dataFromBase64String:geting ];
//getdata = [Base64 decode:geting ];
NSLog(#"getdata is %#",getdata);
dataimages=[UIImage imageWithData:getdata];
NSLog(#"dataImaeg is %#",dataimages);
//[imagearray addObject:dataimages];
myImageView.image=dataimages;
}
}
}
but When i getting image on JSON Data it's not worked. I got This error
Nov 10 14:25:35 Sricharans-iMac.local onlyGeting[3729] : ImageIO: PNG Q[10]U[1E]: invalid chunk type
Nov 10 14:25:35 Sricharans-iMac.local onlyGeting[3729] : ImageIO: PNG Q[10]U[1E]: invalid chunk type
Please tell me What wrong in my code .And Give me any Idea about my problem, image not getting.
Thanks in Advanced.
Is your image getting uploaded? If it doesn't check out for codes of image posting, and also check out if the server backend is working properly
thanks in Advance..
In my app, i have to upload an image to the server, below is my code. code is working properly, as i get the response but problem is that, on server side image is just black.
sessionid=[[[NSUserDefaults standardUserDefaults] valueForKey:#"SessionID"]objectAtIndex:0];
NSLog(#" ID = %#",sessionid);
NSData *da = [NSData data];
da = UIImagePNGRepresentation(self.Profilepic);
NSString *imgStr = [da base64Encoding];
NSLog(#" %d", imgStr.length);
NSString *serverscriptpath=[NSString stringWithFormat:#"http://c4ntechnology.com/biker/web_services/ws_insert_register3.php?"];
NSString *post =[[NSString alloc] initWithFormat:#"profile_pic=%#&sessionid=%#",imgStr,sessionid];
NSLog(#"post string is :%#",post);
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:NO];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSLog(#"post length is :%#",postLength);
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
NSString *script_path=[NSString stringWithFormat:#"%#",serverscriptpath];
[request setURL:[NSURL URLWithString:script_path]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSLog(#"%#",script_path);
NSData *serverReply = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString* responseString = [[[NSString alloc] initWithData:serverReply encoding: NSUTF8StringEncoding] autorelease];
NSDictionary *dict = [responseString JSONValue];
NSLog(#"%#",dict);
[self ReceivedResponse:dict];
-(void)ReceivedResponse:(NSDictionary *)d
{
[AlertHandler hideAlert];
NSLog(#"%#",d);
}
please any one can help me to find out problem, that why on server image is black.?
i am using NSDatAdditions.h file for converting into base64.
when i am using
NSData *imageData = UIImageJPEGRepresentation(Profilepic, 1.0);
at server side, file is not supported occurring, so i used
NSData *da = [NSData data];
da = UIImagePNGRepresentation(self.Profilepic);
You should try using NSUTF8StringEncoding instead of NSASCIIStringEncoding (unless you're sure that the web-server uses ASCII encoding).
If this doesn't work, I'd try the followings:
Encode image as base 64, and afterwards decode it and check if the result is ok.
If 1 passes, check exactly what the server receives (should be the same base64 string as you've sent, otherwise there's probably an issue with different encodings)
As a side note, da = [NSData data]; is useless, since you overwrite it right after, use directly NSData *da = UIImagePNGRepresentation(self.Profilepic);
Im' trying to submit to Reddit via my iOS app. I can login fine and am sent back a modhash and a cookie which I save via NSUserDefaults.
The issue is when I post the data I keep getting "USER_REQUIRED" as the response, even though I have included the modhash in the post and set my session cookie. I have even included the following in my app delegate:
[[NSHTTPCookieStorage sharedHTTPCookieStorage]
setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];
But it still doesn't work. Here is my code:
-(void) post {
NSString *modhash2 = [[NSUserDefaults standardUserDefaults]
objectForKey:#"modhash"];
NSString *urlString = [NSString
stringWithFormat:#"https://ssl.reddit.com/api/submit"];
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
NSString *contentType = [NSString stringWithFormat:#"application/x-www-form-urlencoded;"];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
[request addValue:redditCookie forHTTPHeaderField:#"Cookie"];
[request setHTTPMethod:#"POST"];
NSString *httpBody = [NSString stringWithFormat
:#" ?uh=%#&kind=link&url=%#&sr=%#&title=%#&r=%#&api_type=json",
modhash2,
#"www.google.com",
#"test",
#"Google.com",
#"test"];
[request setHTTPBody:[httpBody dataUsingEncoding:NSASCIIStringEncoding]];
NSURLResponse* response;
NSError* error = nil;
NSData* result = [NSURLConnection
sendSynchronousRequest:request
returningResponse:&response
error:&error];
NSDictionary *json = [NSJSONSerialization
JSONObjectWithData:result
options:NSJSONReadingMutableContainers
error:nil];
NSDictionary *responseJSON = [json valueForKey:#"json"];
NSLog(#"RETURN: %#",responseJSON);
}
Any ideas?
I'm working on a method to centralize my URL connections for sending and receiving JSON data from a server. It works with POST, but not GET. I'm using a Google App Engine server and on my computer it'll handle the POST requests and return proper results (and log appropriately), but I get the following error when I try the request with a GET method:
Error Domain=kCFErrorDomainCFNetwork Code=303 "The operation couldn’t be completed. (kCFErrorDomainCFNetwork error 303.)" UserInfo=0xd57e400 {NSErrorFailingURLKey=http://localhost:8080/api/login, NSErrorFailingURLStringKey=http://localhost:8080/api/login}
In addition, the GAE dev server shows a "broken pipe" error, indicating that the client closed the connection before the server was finished sending all data.
Here's the method:
/* Connects to a given URL and sends JSON data via HTTP request and returns the result of the request as a dict */
- (id) sendRequestToModule:(NSString*) module ofType:(NSString*) type function:(NSString*) func params:(NSDictionary*) params {
NSString *str_params = [NSDictionary dictionaryWithObjectsAndKeys:func, #"function", params, #"params", nil];
NSString *str_url = [NSString stringWithFormat:#"%#%#", lds_url, module];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:str_url]];
NSData *data = [[NSString stringWithFormat:#"action=%#", [str_params JSONString]] dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPMethod:type];
[request setHTTPBody:data];
[request setValue:[NSString stringWithFormat:#"%d", [data length]] forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
NSError *error = nil;
NSURLResponse *response = nil;
NSData *result = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSLog(#"Error: %#", error);
NSLog(#"Result: %#", [[NSString alloc] initWithData:result encoding:NSUTF8StringEncoding]);
return [result objectFromJSONData];
}
A sample call would be:
NSDictionary *response = [fetcher sendRequestToModule:#"login" ofType:#"GET" function:#"validate_email" params:dict];
Again, this works with a POST but not a GET. How can I fix this?
In my case i was not calling [request setHTTPMethod: #"POST" ]
I think the root cause is you have an invalid URL.
JSON encoding will include things like '{', '}', '[' and ']'. All of these need to be URL encoded before being added to a URL.
NSString *query = [NSString stringWithFormat:#"?action=%#", [str_params JSONString]];
query = [query stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *URL = [NSURL URLWithString:[NSString stringWithFormat:#"%#%#", str_url, query]];
To directly answer your question:
According to CFNetwork Error Codes Reference the error is kCFErrorHTTPParseFailure. This means the client failed to correctly parse the HTTP response.
The reason why is that a GET doesn't include a body. Why would you want to submit JSON in a GET anyways?
If the target api returns data only you pass it in the url params.
If you want to send data and "get" a response use a post and examine the body on return.
Sample Post:
NSError *error;
NSString *urlString = [[NSString alloc] initWithFormat:#"http://%#:%#/XXXX/MVC Controller Method/%#",self.ServerName, self.Port, sessionId ];
NSURL *url = [NSURL URLWithString:[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding ]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"POST"];
// hydrate the remote object
NSString *returnString = [rdc JSONRepresentation];
NSData *s10 = [returnString dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPBody:s10];
NSURLResponse *theResponse = [[NSURLResponse alloc] init];
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&theResponse error:&error];
NSString *message = [[NSString alloc] initWithFormat: #"nothing"];
if (error) {
message = [[NSString alloc] initWithFormat:#"Error: %#", error];
} else {
message = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
}
NSLog(#"%#", message);
return message;
This may be a duplicate question but i could not find my answer when searching. So, How do i post data to a url? Heres what i got so far:
NSString *url = #"https://localhost/login.php";
NSURL *urlr = [NSURL URLWithString:url];
NSMutableURLRequest *urlre = [[NSMutableURLRequest alloc] init];
[urlre setURL:[NSURL URLWithString:url]];
NSUserDefaults *defs = [NSUserDefaults standardUserDefaults];
NSString *user = [defs stringForKey:#"User"];
NSString *pass = [defs stringForKey:#"Pass"];
NSInteger *version = [defs integerForKey:#"Version"];
NSString *bodyData = [[NSString alloc] initWithFormat:#"user=%#&password=%#&version=%d",user,pass,version];
NSData *body = [bodyData dataUsingEncoding:NSASCIIStringEncoding];
NSURLResponse *response = nil;
NSError *error = nil;
[urlre setHTTPMethod:#"POST"];
[urlre setValue:[[NSString alloc] initWithFormat:#"%d",[body length]] forHTTPHeaderField:#"Content-Length"];
[urlre setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[urlre setHTTPBody:body];
NSData *dataThis = [NSURLConnection sendSynchronousRequest:urlre returningResponse:&response error:&error];
if(dataThis)
{
NSLog(#"Connect Success");
} else {
NSLog(#"%#",[error localizedDescription]);
}
Is the above correct? In my
-(void) connection:(NSURLConnection*)connection didReceiveData:(NSData *)data
event, I get nothing. Even in the didFinishLoading it gets nothing with NSLog. Please help.
Have you set a delegate for your request?
Why don't you have a look at using a framework like ASIHTTPRequest, makes things so simple. Check it out http://allseeing-i.com/ASIHTTPRequest/
