如何在NSMutableRequest中添加请求参数 [英] How to add request Parameters in NSMutableRequest

问题描述

我创建了一个可变请求。

  NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL：url 
 cachePolicy：NSURLRequestUseProtocolCachePolicy timeoutInterval：60.0]; 
 [请求setHTTPMethod：@POST]; 
 [请求setValue：@application / jsonforHTTPHeaderField：@Content-Type]; 
 //我想添加一个请求参数 - 不在标题或正文中。 
 
在此处添加您的代码
 
 // 
 
 [request setHTTPBody：data]; 
  

任何人请帮帮我

希望这会帮助你

  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]; 
 [请求setHTTPMethod：@POST]; 
 [请求setValue：postLength forHTTPHeaderField：@Content-Length]; 
 [请求setValue：@application / x-www-form-urlencodedforHTTPHeaderField：@Content-Type]; 
 [request setHTTPBody：postData]; 
 NSOperationQueue * queue = [[NSOperationQueue alloc] init]; 
 [NSURLConnection sendAsynchronousRequest：请求队列：队列completionHandler：^（NSURLResponse *响应，
 NSData *数据，NSError *错误）{
 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 download。）; } 
 else if（error！= nil）{
 [[NSOperationQueue mainQueue] addOperationWithBlock：^ {
 
 //这里对你的标签做任何更新
 UIAlertView * alert = [[UIAlertView alloc] initWithTitle：@Message消息：@无法连接到服务器。 delegate：nil cancelButtonTitle：nil otherButtonTitles：@OK，nil]; 
 
 [提示显示]; 
 alert = nil; 
 NSLog（@错误发生=％@，错误）; 
 
}]; 
 
}}]; 
  

I Have created a mutable request .

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];

HOPE THIS WILL HELP YOU

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);

        }];

    } }];
