gnustep 目标 c 中的简单 http 请求不起作用
#import <Foundation/Foundation.h>
main() {
NSURL *url = [NSURL URLWithString:@"http://www.google.com/"];
NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url
cachePolicy:NSURLRequestReloadIgnoringCacheData
timeoutInterval:60];
NSURLResponse *response;
NSError *error;
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSLog(@"Data were download below:\n%@", [[NSString alloc] initWithData:data encoding: NSASCIIStringEncoding]);
}
运行可执行文件 -> 数据下载如下： [空]
为什么？
#import <Foundation/Foundation.h>
main() {
NSURL *url = [NSURL URLWithString:@"http://www.google.com/"];
NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url
cachePolicy:NSURLRequestReloadIgnoringCacheData
timeoutInterval:60];
NSURLResponse *response;
NSError *error;
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSLog(@"Data were download below:\n%@", [[NSString alloc] initWithData:data encoding: NSASCIIStringEncoding]);
}
run the executable ->
Data were download below:
[null]
Why?

您是否尝试过分配请求和错误？
NSURLResponse *response = [[NSURLResponce alloc] init];
NSError *error = [[NSError alloc] init];
Have you tried allocating the request and error?
NSURLResponse *response = [[NSURLResponce alloc] init];
NSError *error = [[NSError alloc] init];
