Question

我有一个这样的方法（这个例子的参数名称故意愚蠢）：

[HttpPost]
        [Route("rest/myMethod")]
        public IHttpActionResult MyMethod(string param1, DateTime param2, DateTime param3, IEnumerable<string> param4, IEnumerable<string> param5 = null)
        {
            return Ok();
        }

但是当我在Swagger中测试时，我得到了这个错误：

{
  "message": "An error has occurred.",
  "exceptionMessage": "Can't bind multiple parameters ('param4' and 'param5') to the request's content.",
  "exceptionType": "System.InvalidOperationException",
  "stackTrace": ""
}

一旦我删除了两个集合参数中的一个，这就可以了。

为什么？如何在WebApi中发布多个对象集合？

感谢。

PS：我不知道这是否是一个有用的智能，但是这个WebApi将从AngularJS客户端调用。

如何在WebApi中发布多个对象集合？

将它们包装在视图模型中：

#!/bin/bash

# run program, invoke in model directory with input files.

# we want to run in the current working directory
#$ -cwd

# we want to run mpi with 4 cores on he same node:
#$ -pe sharedmem 4

# make a generous guess at the time we need
#$ -l h_rt=30:00:00

# force reservation
#$ -R y

# use 4G per process

#$ -l h_vmem=4G

# hold the array

#$ -h

echo I am task $SGE_TASK_ID in $JOB_ID with $SGE_TASK_LAST tasks in total

echo on $HOSTNAME
date
# run our model - set modules, then get the model name 

echo "set modules"

. /etc/profile.d/modules.sh

PROGRAMBUILD=/exports/programlocation
. $PROGRAMBUILD/loadModules.sh

modelName=$(basename $PWD)

echo mpirun -np 4  $PROGRAMBUILD/bin/program $modelName 
mpirun -np 4  $PROGRAMBUILD/bin/program $modelName 


if [ $SGE_TASK_ID == $SGE_TASK_LAST ]
then
    echo I am last task
else
    # release the next task....
    # next task in this array:
    next=$((SGE_TASK_ID+1))

    echo insert a test that this task in the array job was successful
    echo if so, release next task
    echo releasing $next
    ssh login01.***.uk qrls $JOB_ID.$next

    if [[ "$?" -ne 0 ]]; then
        echo failed to qrls $pid
    fi

fi

你的POST动作将作为参数：

public class MyViewModel
{
    public string Param1 { get; set; }
    public DateTime Param2 { get; set; }
    public DateTime Param3 { get; set; }
    public IEnumerable<string> Param4 { get; set; }
    public IEnumerable<string> Param5 { get; set; }
}

现在您可以收到以下请求：

[HttpPost]
[Route("rest/myMethod")]
public IHttpActionResult MyMethod(MyViewModel model)
{
    return Ok();
}

POST多个集合
