如何使用post方法发布字典和数组服务器

Question

如何发布json服务器我正在尝试添加字典和发布数据，但未获得写入响应

{“type”：“普通”，"noteText":{"lineNo":"1"，“lineText”：“患者入院”}}

NSURLSessionConfiguration *configuration = NSURLSessionConfiguration defaultSessionConfiguration；NSURLSession *session = NSURLSession sessionWithConfiguration:配置委派:自委派队列:空；

NSString *Str = @"general";
  NSString *St2r = @"Yogesh";
NSString *Str1 = @"1";

NSMutableArray *临时数组= [NSMutableArray分配数组]；

NSDictionary *tempDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
                               Str1, @"lineNo",
                             St2r, @"lineText",
                                nil];
[tempArray addObject:tempDictionary];

NSDictionary *tempDict = [[NSDictionary alloc]initWithObjectsAndKeys:tempArray,@"noteText", nil];
NSError *error;

NSData *postData = [NSJSONSerialization dataWithJSONObject:tempDict options:0 error:&error];

//请求setHTTPBody:postData；

NSString *jsonRequest = NSString字符串格式：@“{\”类型\“：\”%@\“}”，Str；// NSLog(@“请求：%@"，jsonRequest)；

NSURL *url7 = [NSURL URLWithString:@"URl"];

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url7];
NSData *requestData = [NSData dataWithBytes:[jsonRequest UTF8String] length:[jsonRequest length]];
[request setHTTPBody:postData];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody: requestData];


NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)

{

    if(error == nil)
    {
        NSString * text = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];
        NSLog(@"Data = %@",text);
    }

}];

也许可以考虑使用AFNetworking？

您可以从here下载代码

使用以下代码作为对服务器的post调用的示例。

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = @{@"foo": @"bar"};
[manager POST:@"http://example.com/resources.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];
