后台是Java，今天他们要求和上传Json到服务器，方法如下：
iOS 如何用post方式上传son数据 — ASI
{
NSString *newUrl = [[NSString alloc] initWithFormat:@"%@register/json", ABC];
NSURL *target = [[NSURL alloc]initWithString:newUrl];
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
username, @"name",
password, @"password",
nil];
AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:target];
client.parameterEncoding = AFJSONParameterEncoding;
[client postPath:@"" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
[self registerRequestFinished:operation];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
[self RequestFailed:error];
}];
}
这里使用的是AFNetworking这个库，内容传递使用的是Json，至少在Url上是看不出内容来的
顺便提供一段使用系统内置库解析Json的代码：NSDictionary *result = [NSJSONSerialization JSONObjectWithData:[jsonResult dataUsingEncoding:NSUTF8StringEncoding] options:0 error:nil];

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"]; // 设置content-Type为text/html
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
