iosafn怎麼用post上傳json數據

代碼如下：

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

//申明返回的結果是json類型

manager.responseSerializer = [AFJSONResponseSerializer serializer];

//申明請求的數據是json類型

manager.requestSerializer=[AFJSONRequestSerializer serializer];

//如果報接受類型不一致請替換一致text/html或別的

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@”text/html”];

//傳入的參數

NSDictionary *parameters = @{@”1″:@”XXXX”,@”2″:@”XXXX”,@”3″:@”XXXXX”};

//你的介面地址

NSString *url=@”http://”;

//發送請求

[manager POST:url parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {

NSLog(@”JSON: %@”, responseObject);

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

NSLog(@”Error: %@”, error);

ios以post請求傳來的json 在java怎麼獲取？？

MapString, String[] paramMap = request.getParameterMap();

String data = paramMap.get(“param”)[0];//這裡要看它是怎麼放的。

ObjectMapper mapper = new ObjectMapper();

 MapString, Object map=mapper.readValue(data , Map.class);

2020-07-30 ios post請求方式表單與Json

最近遇到的坑，兩個後台，一個表單，一個Json格式，之前一直沒搞明白

附上源碼供參考

iOS post請求向伺服器發送json格式數據（數組或字典）

1.字典

（ps  usernames 是欄位，jsonString是轉換json格式的字典）

2.數組

數組其實和字典一樣，只需將（dataWithJSONObject： dicFriends ）參數，換成數組就可以了
