如何使用post mathods发布字典和数组服务器-Java 学习之路

如何发布json服务器我正在尝试添加字典和发布数据但没有得到写入响应

{“type”：“general”，“noteText”：[{“lineNo”：“1”，“lineText”：“patient admited”}]}

NSURLSessionConfiguration * configuration = [NSURLSessionConfiguration defaultSessionConfiguration]; NSURLSession * session = [NSURLSession sessionWithConfiguration：configuration delegate：self delegateQueue：nil];

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

NSMutableArray * tempArray = [[NSMutableArray alloc] init];

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];

// [request setHTTPBody：postData];

NSString * jsonRequest = [NSString stringWithFormat：@“{\”type \“：\”％@ \“}”，Str]; // NSLog（@“Request：％@”，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);
    }

}];

考虑使用AFNetworking吗？

你可以从here下载代码

使用以下代码作为对服务器的后调用的示例 .

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);
}];
