HashMap的JSON表示

Question

for (i = 0; i < size; i++) MPI_Irecv(&data[i*100], 100, MPI_INT, i, 0, comm, &requests[i]); /* No touching data in here */ MPI_Waitall(i, requests, statuses); /* You can touch data here */ for (i = 0; i < size; i++) MPI_Isend(&data[i*100], 100, MPI_INT, i+1, 0, comm); /* i+1 is wherever you want to send the data */ /* No touching data in here either */ MPI_Waitall(i, requests, statuses); 的Json表示是什么？

我尝试过这种方式，但收到错误的请求错误。

HashMap<String, String>

Answer 1

"userPreferences":{"mobile":"yes","email":"yes"}

Answer 2

应该是这样的

{ "userPreferences":{"mobile":"yes","email":"yes"} }

Answer 3

您拥有的JSON即使是JavaScript对象也无效，因为您尚未为两个“内部”对象定义属性名称。 HashMap基本上是一组键值对。您的JSON应该如下所示：

"userPreferences": {
    "mobile": "yes",
    "email": "yes"
}
