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？？

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

String data = paramMap.get(“param”)[0];//这里要看它是怎么放的。

ObjectMapper mapper = new ObjectMapper();

 MapString, 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）

1.字典

（ps  usernames 是字段，jsonString是转换json格式的字典）

2.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
