iosafn怎么用post上传json数据

代码如下：

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
//申明返回的结果是json类型
manager.responseSerializer = [AFJSONResponseSerializer serializer];
//申明请求的数据是json类型
manager.requestSerializer=[AFJSONRequestSerializer serializer];
//如果报接受类型不一致请替换一致text/html或别的
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
//传入的参数
NSDictionary *parameters = @{@"1":@"XXXX",@"2":@"XXXX",@"3":@"XXXXX"};
//你的接口地址
NSString *url=@"http://";
//发送请求
[manager POST:url parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

ios以post请求传来的json 在java怎么获取？？

Map<String, String[]> paramMap = request.getParameterMap();
String data = paramMap.get("param")[0];//这里要看它是怎么放的。
ObjectMapper mapper = new ObjectMapper();
Map<String, Object> map = mapper.readValue(data, Map.class);

2020-07-30 ios post请求方式表单与Json

最近遇到的坑，两个后台，一个表单，一个Json格式，之前一直没搞明白附上源码供参考

iOS post请求向服务器发送json格式数据（数组或字典）

字典（ps usernames 是字段，jsonString是转换json格式的字典）
数组数组其实和字典一样，只需将（dataWithJSONObject： dicFriends ）参数，换成数组就可以了
