ios - 如何在 NSMutableRequest 中添加请求参数

Question

我创建了一个可变请求。

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
                                                         cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
    [request setHTTPMethod:@"POST"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
// I want to add a request parameter - Not in the header or body.

   Add Your code here

//

[request setHTTPBody:data];

任何人请帮助我

NSString *post=[NSString stringWithFormat:@"data={\"user_id\":\"abc\",\"Method\":\"User_nji_abc\"}"];

NSURL *url=[NSURL URLWithString:YOUR_BASE_URL];

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

NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init] ;
[request setURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];
NSOperationQueue *queue=[[NSOperationQueue alloc]init];
[NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response,
                                                                                 NSData *data, NSError *error) {
    if ([data length] >0 && error == nil){


        dicWholeValue=[NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error];


        NSLog(@"%@",dicWholeValue);

    }
    else if ([data length] == 0 && error == nil){
        NSLog(@"Nothing was downloaded."); }
    else if (error != nil){
        [[NSOperationQueue mainQueue] addOperationWithBlock:^{

            //Do any updates to your label here
            UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"Message" message:@"Could not connect to server." delegate:nil cancelButtonTitle:nil otherButtonTitles:@"OK", nil];

            [alert show];
            alert=nil;
            NSLog(@"Error happened = %@", error);

        }];

    } }];
