如何在iOS中发送Get请求？

Question

我正在创建一个库来获取具有指定数据和方法类型的特定URL的响应.为此,我正在使用url提出请求.但是当我设置它的方法类型时,它显示了一个异常的无法识别的选择器发送,[NSURLRequest setHTTPMethod:] 我将其设置为

[requestObject setHTTPMethod:@"GET"];

告诉我可能是什么问题.如果你有,也提供给我代码.

Answer 1

NSMutableURLRequest *request = 
[NSMutableURLRequest requestWithURL:[NSURL 
            URLWithString:serverAddress] 
            cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData
                                                   timeoutInterval:10
 ];

[request setHTTPMethod: @"GET"];

NSError *requestError = nil;
NSURLResponse *urlResponse = nil;


NSData *response1 =
        [NSURLConnection sendSynchronousRequest:request
                         returningResponse:&urlResponse error:&requestError];

Answer 2

NSString *getString = [NSString stringWithFormat:@"parameter=%@",yourvalue];
NSData *getData = [getString dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

NSString *getLength = [NSString stringWithFormat:@"%d", [getData length]];

NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];

[request setURL:[NSURL URLWithString:@"https:yoururl"]];

[request setHTTPMethod:@"GET"];

[request setValue:postLength forHTTPHeaderField:@"Content-Length"];

[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];

[request setHTTPBody:getData];

self.urlConnection = [[[NSURLConnection alloc] initWithRequest:request delegate:self] autorelease];

NSAssert(self.urlConnection != nil, @"Failure to create URL connection.");

// show in the status bar that network activity is starting
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
