Question

我正在学习Django 1.6。
我想使用HTTP POST请求发布一些JSON，我正在使用Django来完成此任务的学习我尝试使用request.POST['data']，request.raw_post_data，request.body，但没有一个适合我我的views.py是

import json
from django.http import StreamingHttpResponse
def main_page(request):
    if request.method=='POST':
            received_json_data=json.loads(request.POST['data'])
            #received_json_data=json.loads(request.body)
            return StreamingHttpResponse('it was post request: '+str(received_json_data))
    return StreamingHttpResponse('it was GET request')

我使用requests模块发布JSON数据。

import requests  
import json
url = "http://localhost:8000"
data = {'data':[{'key1':'val1'}, {'key2':'val2'}]}
headers = {'content-type': 'application/json'}
r=requests.post(url, data=json.dumps(data), headers=headers)
r.text

r.text应该打印该消息并发布数据，但我无法解决这个简单的问题。请告诉我如何在Django 1.6中收集发布的数据？

Answer 1

您在这里混淆了表单编码和JSON数据。 request.POST['foo']用于表单编码数据。您正在发布原始JSON，因此您应该使用request.body。

received_json_data=json.loads(request.body)

Answer 2

对于python3，你必须首先解码body：

$(document).ready(function(){ 
     $("body").on("change", "input[type='checkbox']",function() {
        var that = this;
        if (!$(this).parent().hasClass("remember-label")){
          $(this).parent().css("background-color", function() {
              return that.checked ? "#C0E9F7" : "";
          });
        }
    });
    $("body").on("click", "input[type=radio]" ,function() {
      $(this).parents().eq(1).siblings().css("backgroundColor","");
      $(this).parents().eq(1).css("backgroundColor","#C0E9F7");
    });
});

一种方法是使用ajax。

前端（javascript）：-

// LIB

type Arguments<T> = [T] extends [(...args: infer U) => any]
  ? U
  : [T] extends [void] ? [] : [T]

interface TypedEventEmitter<Events> {
  addListener<E extends keyof Events> (event: E, listener: Events[E]): this
  on<E extends keyof Events> (event: E, listener: Events[E]): this
  once<E extends keyof Events> (event: E, listener: Events[E]): this
  prependListener<E extends keyof Events> (event: E, listener: Events[E]): this
  prependOnceListener<E extends keyof Events> (event: E, listener: Events[E]): this

  removeAllListeners<E extends keyof Events> (event: E): this
  removeListener<E extends keyof Events> (event: E, listener: Events[E]): this

  emit<E extends keyof Events> (event: E, ...args: Arguments<Events[E]>): boolean
  eventNames (): (keyof Events)[]
  listeners<E extends keyof Events> (event: E): Function[]
  listenerCount<E extends keyof Events> (event: E): number

  getMaxListeners (): number
  setMaxListeners (maxListeners: number): this
}

// MY CODE

export const awaitNextEvent = <
  Events extends { [k: string]: Function },
  Event extends keyof Events
>(
  eventEmitter: TypedEventEmitter<Events>,
  event: Event,
) =>
  // Type 'Events[Event]' does not satisfy the constraint '(...args: any) => any'.
  new Promise<Parameters<Events[Event]>>(resolve => {
    // Type '(...args: any[]) => void' is not assignable to type 'Events[Event]'
    const cb: Events[Event] = ((...args) => {
      resolve(args);
    });
    eventEmitter.once(event, cb);
  });

const t:TypedEventEmitter<{'ev':(arg:string)=>void,'ev2':()=>void}> = 1 as any

// ret is a Promise<[string]> as expected
const ret = awaitNextEvent(t,'ev')

后端（views.py）：-

var data_to_send = {}; //push 'values to send' into this. $.ajax({
      ..... //other ajax attributes
      data: {'val': JSON.stringify(data_to_send)},
      ..... //other ajax attributes });

创建一个表单，其数据为CharField或TextField类型的字段，并验证传递的数据。 Similar SO Question
