我想使用
JSON数据类型使用POST方法将在iOS上创建的新对象发送到接收服务器.根据我对从iOS服务器接收数据的了解,苹果公司通过引入iOS 5简化了所有JSON处理.但与GETting JSON对象相比,POST这些并不是我能找到的任何地方. .
我尝试解决问题的第一步看起来如下：
//build an info object and convert to json
NSDictionary *newDatasetInfo = [NSDictionary dictionaryWithObjectsAndKeys:name,@"name",language,@"language",nil];
//convert object to data
NSData* jsonData = [NSJSONSerialization dataWithJSONObject:newDatasetInfo options:kNilOptions error:&error];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:someURLSetBefore];
[request setHTTPMethod:@"POST"];
// any other things to set in request? or working this way?
[[NSURLConnection alloc] initWithRequest:request delegate:self];
// What to do with NSURLConnection? Or how to send differently?
但我真的不知道如何使用POST方法将JSON对象发送到服务器.
有人可以帮帮我吗？
解决方法
我通过尝试一下来解决这个问题,这是我的代码：
//build an info object and convert to json
NSDictionary *newDatasetInfo = [NSDictionary dictionaryWithObjectsAndKeys:name,nil];
//convert object to data
NSData* jsonData = [NSJSONSerialization dataWithJSONObject:newDatasetInfo options:kNilOptions error:&error];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:someURLSetBefore];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setHTTPBody:jsonData];
// print json:
NSLog(@"JSON summary: %@",[[NSString alloc] initWithData:jsonData
encoding:NSUTF8StringEncoding]);
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
[connection start];
