在AFNetworking的帮助下调用Web服务目标C

Question

我正在使用NSURLConnection方法调用Web服务，我希望将其替换为第三方库AFNetworking我应该如何实现这一点我正在使用数据调用Web服务这里的时间就是我目前所做的。

- (void)viewDidLoad { 
    [super viewDidLoad]; 
    NSURL * linkUrl = [NSURL URLWithString:@URLBase]; 
    NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:linkUrl]; 
    NSString *msgLength = [NSString stringWithFormat:@"%lu", (unsigned long)[str length]]; 

    [theRequest addValue: @"text/plain; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; 
    [theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"]; 
    [theRequest setHTTPMethod:@"POST"]; 
    [theRequest setHTTPBody: [str dataUsingEncoding:NSUTF8StringEncoding]]; 

    NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; 


    if(theConnection) 
    { 
     webData = [[NSMutableData alloc] init]; 

    } 
    else 
    { 
     NSLog(@"theConnection is NULL"); 
    } 
    } 
#pragma mark -- Connection Delegate 
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response 
{ 
    //NSLog(@"%@",response); 
    //[webData setLength: 0]; 

} 
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data 
{ 
    [webData appendData:data]; 

} 
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error 
{ 
    NSLog(@"\nERROR with theConenction"); 

} 
-(void)connectionDidFinishLoading:(NSURLConnection *)connection 
{ 
    NSString *responseDataString = [[NSString alloc] initWithData:webData encoding:NSUTF8StringEncoding]; 
    NSLog(@"Converted NSData %@ ",responseDataString); 

} 

这里

[theRequest setHTTPBody: [str dataUsingEncoding:NSUTF8StringEncoding]]; 

str是我喜欢的用户名和密码进行加密的数据。 在此先感谢。

您需要将POST请求发送到您的Web服务。您可以使用以下代码片段进行旧式操作。

NSString *post = [NSString stringWithFormat:@"%@&value=%@&value=%@&value=%@&value=%@&value=%@",self.Comment_Memberid,self.SharedID,self.Post_Ownerid,self.commentText.text,email_stored,password_stored]; 

    NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES]; 

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; 
    [request setURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://.../api/json/postcomment/"]]]; 
    [request setHTTPMethod:@"POST"]; 
    [request setValue:[NSString stringWithFormat:@"%lu", (unsigned long)[postData length]] forHTTPHeaderField:@"Content-Length"]; 
    [request setValue:@"text/plain; charset=utf-8" forHTTPHeaderField:@"Content-type"]; 
    //[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-type"]; 
    [request setHTTPBody:postData]; 
    //get response 
    NSHTTPURLResponse* urlResponse = nil; 
    NSError *error = [[NSError alloc] init]; 
    NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error]; 
    NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; 
    NSLog(@"Response Code: %ld", (long)[urlResponse statusCode]); 

    if ([urlResponse statusCode] == 200) 
    { 

    } 

如果你想与AFNetworking您可以使用下面的代码中使用发送POST请求：

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; 
NSDictionary *params = @{@"34": x, 
         @"130": y}; 
[manager POST:@"https://../api/json/cordinates" parameters:params progress:nil success:^(NSURLSessionTask *task, id responseObject) { 
    NSLog(@"JSON: %@", responseObject); 
} failure:^(NSURLSessionTask *operation, NSError *error) { 
    NSLog(@"Error: %@", error); 
}];
