NSMutableURLRequest 设置 header

2019-12-03
IOS, 笔记
NSString *strUrl=[NSString stringWithFormat:@"你的地址"];
NSURL *url=[NSURL URLWithString:strUrl];
NSMutableURLRequest *request=[[NSMutableURLRequest alloc]initWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:20];
[request setHTTPMethod:@"GET"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];//这个很关键，一定要设置
[request setValue:@"字段对应的值1" forHTTPHeaderField:@"你头部的字段1"];／／这里就是你自己对应的参数
mConn=[[NSURLConnection alloc]initWithRequest:request delegate:self startImmediately:true];
[mConn start];
