将列表数据从angular发送到django rest

我正在学习angular，现在我想将数据数组发送到django rest框架，我尝试使用

HttpParams

，

JSON.stringyfy（）

，但没有任何数据是空的

角度代码：

public getSymptomsList(symptomList:string[]){
    console.log(symptomList)

    return this.httpClient.post(`${this.ApiUrl}diagnos/`, {PASS_DATA_HERE},{headers: new HttpHeaders().set('Authorization', `Token ${this.AuthToken}`),});

  }

Djnago API代码：

class diagnos(APIView):
    def post(self, request):
        symptomlist = request.POST.getlist('symptoms')
        print(symptomlist)
        ...

但当我尝试使用terminal by

httpie

时，它给出了以下结果：

bhupesh@Laptop:~$ http -f POST http://127.0.0.1:8000/api/diagnos/ symptoms='fever' symptoms='urinoma'

        "name": "uncoordination"
    },
    {
        "name": "fever"
    },
    {
        "name": "pleuritic pain"
    },
    {
        "name": "snuffle"
    },
    {
        "name": "throat sore"
    },
    {
        "name": "malaise"
    },
    {
        "name": "debilitation"
    }
]

尝试将您的请求转换为：

public getSymptomsList(symptoms:string[]){

    return this.httpClient.post(`${this.ApiUrl}diagnos/`, {symptoms},{headers: new HttpHeaders().set('Authorization', `Token ${this.AuthToken}`),});

  }

使用此代码，主体将是一个具有字段符号的对象

{
"symptoms": ["a","b","c"]
}

当请求完成时，您在“网络”选项卡中看到了什么？即使我打印了请求，请求也会成功执行。其中的body会打印列表，但不会作为post数据发送
