ASIFormDataRequest post类型

Question

我需要发送post类型的RestFul网络服务请求，post数据格式如下{" Request ":"parameters"....}和具有相同request.Is的二进制数据在ios中是否可能，如果可能，请解释？

我不再推荐使用ASIHttpRequest库，因为它不会从开发人员那里获得任何更新，至于如何创建post http请求，下面是一个示例

NSString *url = @"your webservice base url";
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:url]];

[request setHTTPMethod:@"POST"];

NSString *param2 = ...//
NSData *binaryData = .... //initilize the binary data you want to send
NSString *bodyString = [NSString stringWithFormat:@"param1=%@&param2=%@",binartData,param2];



[request setValue:[NSString stringWithFormat:@"%d", [bodyString length]] forHTTPHeaderField:@"Content-length"];
[request setHTTPBody:[bodyString dataUsingEncoding:NSASCIIStringEncoding]];//or set the type of encoding agreed with your webservice

NSURLResponse *response = nil;
NSError *error = nil;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

NSString *responseString;
if ( responseData && !error){
    responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];

}
