我想在
JSON中发布一个数组值.
以下是我的代码:
-(void)getConnection {
NSArray *comment=[NSArray arrayWithObjects:@"aaa",@"bbb",@"ccc",@"hello,yes,tell", nil];
NSURL *aurl=[NSURL URLWithString:@"http://sajalaya.com/taskblazer/staffend/form/iphonearraytest.php"];
NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:aurl cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPMethod:@"POST"];
NSData *jsonData2 = [NSJSONSerialization dataWithJSONObject:comment options:NSJSONWritingPrettyPrinted error:nil];
NSString *new = [[NSString alloc] initWithData:jsonData2 encoding:NSUTF8StringEncoding];
// NSString *new = [comment JSONString];
// NSArray *new=[comment jsonvalue];
NSString *postString=[NSString stringWithFormat:@"tag=&comment=%@&total=%@",new,@"4"];
NSLog(@"this is post string%@",postString);
[request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];
[NSURLConnection connectionWithRequest:request delegate:self];
}
最佳答案 我们不知道你的问题,但我的答案简短而简单.你应该使用优秀的开源库,这是:
AFNetworking,并做这样的请求:
_httpClient = [[AFHTTPClient alloc] initWithBaseURL:[[NSURL alloc] initWithString:@"http://sajalaya.com"]];
[_httpClient registerHTTPOperationClass:[AFJSONRequestOperation class]];
NSData *jsonData2 = [NSJSONSerialization dataWithJSONObject:comment options:NSJSONWritingPrettyPrinted error:nil];
NSString *new = [[NSString alloc] initWithData:jsonData2 encoding:NSUTF8StringEncoding];
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
new, @"comment",
@4, @"total,
nil];
NSMutableURLRequest *request = [self.httpClient requestWithMethod:@"POST"
path:@"/taskblazer/staffend/form/iphonearraytest.php"
parameters:params];
request.timeoutInterval = 8;
AFJSONRequestOperation *operation = [[AFJSONRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
// success
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
// failure
}];
