将列表数据从角度发送到 django rest

Question

我正在学习角度，现在我想将数据数组发送到 django rest 框架，我尝试使用 HttpParams,JSON.stringyfy()，但没有任何工作数据会为空

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)
        ...

但是当我尝试通过httpie 使用终端时，它给出了结果：

bhupesh@Laptop:~$ http -f POST http://127.0.0.1:8000/api/diagnos/ symptoms='fever' symptoms='urinoma'
HTTP/1.1 200 OK

    }

Answer 1

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，主体将是一个具有类似这样的字段符号的对象

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