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
