NSData *postData = [jsonStringdataUsingEncoding:NSUTF8StringEncodingallowLossyConversion:YES];

NSMutableURLRequest *request = [NSMutableURLRequestrequestWithURL:[NSURLURLWithString:urlStr]];

[request setHTTPMethod:@"POST"];

[request setHTTPBody:postData];

NSString* postDataLengthString = [[NSStringalloc] initWithFormat:@"%d", [postDatalength]];

[request setValue:@"application/x-www-form-urlencoded"forHTTPHeaderField:@"Content-Type"];

[request setValue:postDataLengthStringforHTTPHeaderField:@"Content-Length"];

NSError *error =nil;

NSURLResponse *responses;

NSData *data = [NSURLConnectionsendSynchronousRequest:request returningResponse:&responseserror:&error];

NSDictionary *responseDic =nil;

NSDictionary *responseDic = [NSJSONSerializationJSONObjectWithData:dataoptions:NSJSONReadingMutableLeaveserror:nil];

Content-Type 的类型有多种，在此用到了application/x-www-form-urlencoded，这也是一种默认的类型，大家可以搜一下HTTP的Content-Type类型
