我需要为请求设置HTTP标头。在NSURLRequest类的文档中,我没有找到有关HTTP标头的任何信息。如何设置HTTP标头以包含自定义数据?
Answers:
您需要使用NSMutableURLRequest
NSMutableURLRequest* request = [[[NSMutableURLRequest alloc] initWithURL:url]
autorelease];
[request setValue:VALUE forHTTPHeaderField:@"Field You Want To Set"];
或添加标题:
[request addValue:VALUE forHTTPHeaderField:@"Field You Want To Set"];
对于斯威夫特
let url: NSURL = NSURL(string: APIBaseURL + "&login=1951&pass=1234")!
var params = ["login":"1951", "pass":"1234"]
request = NSMutableURLRequest(URL:url)
request.HTTPMethod = "POST"
var err: NSError?
request.HTTPBody = NSJSONSerialization.dataWithJSONObject(params, options: nil, error: &err)
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
request.setValue("Some value", forHTTPHeaderField: "Content-Type")
这对你有用吗?
NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:60];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"your value" forHTTPHeaderField:@"for key"];//change this according to your need.
[request setHTTPBody:postData];
我知道它来晚了,但可能会对其他人有所帮助,对于SWIFT 3.0
let url = NSURL(string: "http://www.yourwebsite.com")
let mutAbleRequest = NSMutableURLRequest(URL: url!)
mutAbleRequest.setValue("YOUR_HEADER_VALUE", forHTTPHeaderField:"YOUR_HEADER_NAME")
myWebView.loadRequest(mutAbleRequest)
您可以NSMutableURLRequest
为HeaderField添加值:
NSMutableURLRequest* request = [[NSMutableURLRequest alloc] initWithURL:url];
[request setValue:VALUE forHTTPHeaderField:@"cookie"];
这对我有用。
样例代码
- (void)reqUserBalance:(NSString*)reward_scheme_id id:(NSString*)user_id success:(void (^)(id responseObject))success failure:(void (^)(id responseObject))failure{
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@reward/%@/user/%@/balance",URL_SERVER,reward_scheme_id,user_id]];
NSLog(@"%@",url);
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"true" forHTTPHeaderField:@"Bypass"];
[NSURLConnection sendAsynchronousRequest:request
queue:[NSOperationQueue mainQueue]
completionHandler:^(NSURLResponse *response,
NSData *data, NSError *connectionError)
{
options:kNilOptions error:NULL];
if (data.length > 0 && connectionError == nil)
{
NSDictionary * userPoints = [NSJSONSerialization JSONObjectWithData:data
options:0
error:NULL];
NSString * points = [[userPoints objectForKey:@"points"] stringValue];
NSLog(@"%@",points);
[SecuritySetting sharedInstance].usearAvailablePoints = points;
}
}];
}
