How to pass multiple parameters in URL to web View in iOS? - ios

Question

I have following dictionary:
NSDictionary *param = #{#"schoolid":#"schooldb1",
#"token":del.tokenString,
#"mobile":del.phoneString
};
NSLog(#"param:%#",param);
I want to send this parameters (schoolid, token, mobile) to web view. But I don't know how to send that. I tried to search on internet but I didn't get any proper solution for my question.
My main URL is:
NSString *url=#"https://MyURL.com/School/AppSingleTrack";
and I'm going to call UIWebview like following:
NSString *finalurl=[NSString stringWithFormat:#"https://MyURL.com/School/AppSingleTrack/?%#",param];
NSURL *nsurl=[NSURL URLWithString:finalurl];
NSURLRequest *nsrequest=[NSURLRequest requestWithURL:nsurl];
[_webview loadRequest:nsrequest];
[self.view addSubview:_webview];

Answer 1

Try like this,
NSDictionary *param = #{#"schoolid":#"schooldb1",
#"token":del.tokenString,
#"mobile":del.phoneString
};
NSLog(#"param:%#",param);
NSString *url=#"https://24x7tracker.com/School/AppSingleTrack";
NSString *finalurl=[NSString stringWithFormat:#"https://24x7tracker.com/School/AppSingleTrack/"];
NSURL *nsurl=[NSURL URLWithString:finalurl];
NSMutableURLRequest *nsrequest=[NSMutableURLRequest requestWithURL:nsurl];
NSData *data = [NSJSONSerialization dataWithJSONObject:param options:0 error:nil];
[nsrequest setHTTPBody:data];
[_webview loadRequest:nsrequest];
[self.view addSubview:_webview];
set request's necessary properies if require like [nsrequest setHTTPMethod:#"GET"]; or POST and contentType etc.
You should use AFNetworking, It will make it more easier.

Use this Code,
NSString *sUrl = #"https://24x7tracker.com/School/AppSingleTrack";
NSMutableURLRequest *res = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:sUrl]];
[res setHTTPMethod:#"POST"];
NSDictionary *params; = [NSDictionary dictionaryWithObjectsAndKeys:
#"schooldb1",#"schoolid",
del.tokenString,#"token",
del.phoneString,#"mobile",
nil];
NSMutableArray *pairArray = [[NSMutableArray alloc] initWithCapacity:0];
for (NSString *key in params)
[pairArray addObject:[NSString stringWithFormat:#"%#=%#", key, params[key]]];
[res setHTTPBody:[[pairArray componentsJoinedByString:#"&"] dataUsingEncoding:NSUTF8StringEncoding]];
[NSURLConnection sendAsynchronousRequest:res
queue:[NSOperationQueue mainQueue]
completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
NSLog(#"request URL : %#",res.URL);
NSLog(#"request Method : %#",res.HTTPMethod);
NSLog(#"parameters : %#",params);
NSLog(#"response : %#",response);
Resp *r = [ [Resp alloc] initWithDictionary:[NSJSONSerialization JSONObjectWithData: data options: NSJSONReadingMutableContainers error:nil]];
// Success - Show Sucess message
if ([r.sCode isEqualToString:#"success"]) {
NSLog(#"response message : %#",r.sData);
}
}];
Use the Class Resp:
Resp.h
#import <Foundation/Foundation.h>
#interface Resp : NSObject
#property (nonatomic, copy) NSString *sCode;
#property (nonatomic, copy) NSString *sMessage;
#property (nonatomic, copy) NSString *sData;
- (id)initWithDictionary:(NSDictionary *)dictionary;
#end
Resp.m
#import "Resp.h"
#implementation Resp
#synthesize sCode = _id;
#synthesize sMessage = _title;
#synthesize sData = _data;
- (id)initWithDictionary:(NSDictionary *)dictionary {
self = [super init];
if (self) {
self.sCode = [dictionary objectForKey:#"code"];
self.sMessage = [dictionary objectForKey:#"message"];
self.sData = [dictionary objectForKey:#"data"];
}
return self;
}
#end
then finally get the response, hope its helpful

Firstly, talk to your colleague or check the documents of the URL, to confirm what format of parameters the API needs, and the Request method, such as GET or POST.
Secondly, concatenate the params to the proper format, and don't forget escape the parameters.
If your URL need parameters as normal, try these:
NSDictionary *params = #{#"schoolid" : #"",
#"token" : #"",
#"mobile" : #""};
NSMutableArray *keyValues = [NSMutableArray array];
for (NSString *key in params) {
[keyValues addObject:[NSString stringWithFormat:#"%#=%#&", key, params[key]]];
}
NSString *paramsString = [keyValues componentsJoinedByString:#"&"];
paramsString = [paramsString stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
// Don't add / at last unless the URL has, because / is another path
NSString *baseURL = #"https://24x7tracker.com/School/AppSingleTrack";
// If GET, you can use these two lines, or use below
// NSString *urlString=[NSString stringWithFormat:#"%#?%#", baseURL, paramsString];
// NSURLRequest *request=[NSURLRequest requestWithURL:[NSURL URLWithString:urlString]];
// if POST
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:baseURL]];
request.HTTPMethod = #"POST"; // Default is GET, you can send get request by default,
request.HTTPBody = [paramsString dataUsingEncoding:NSUTF8StringEncoding];
[webView loadRequest:request];
Edit:
According to #Shubhank's guess, if the webview's request via ajax, you should confirm the function of javascript, and try these codes in webview's delegate webViewDidFinishLoad:
- (void)webViewDidFinishLoad:(UIWebView *)webView {
[webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:#"javascriptFunction(%#, %#, %#)", param1, param2, param3]];
}
