Question

我的金字塔框架存在严重问题。我将此功能添加到金字塔

add_cors_headers_response_callback(event):
    def cors_headers(request, response):
        response.headers.update({
        'Access-Control-Allow-Origin': '*',
        'Access-Control-Allow-Methods': 'POST,GET,DELETE,PUT,OPTIONS',
        # 'Access-Control-Allow-Methods': 'DELETE, OPTIONS',
        'Access-Control-Allow-Headers': 'Origin, Content-Type, Accept, Authorization',
        'Access-Control-Allow-Credentials': 'true',
        'Access-Control-Max-Age': '1728000',
        })
    event.request.add_response_callback(cors_headers)

from pyramid.events import NewRequest
config.add_subscriber(add_cors_headers_response_callback, NewRequest)

我可以使用GET，POST方法向我的服务器发出请求。问题是，当我使用PUT AND DELETE方法时，服务器发送HTTP状态404，但当我卷曲路径时，我得到答案（或使用POSTMAN）。

我对Node.JS使用相同的Angular http查询，它接受我的请求。我不知道为什么金字塔拒绝服务于观点

updatePatternModel(newPattern,url) {
    let fullurl = this.baseUrl + url;
    let data = {
      "rule":newPattern
    }; 
    return this.http.put(fullurl,JSON.stringify(data))
      .map(response => response.json())
      .catch(err => this.handleErrorObservable(err));
  }

金字塔

@view_config(request_method='PUT', route_name='gm')
    def gm(self):
        return dict()

我举个例子

from pyramid.view import view_config

@view_config(route_name='gm', renderer='json',request_method="GET")
def get(request):
    return dict(hello="GET")


@view_config(route_name='gm', renderer='json',request_method="POST")
def post(request):
    return dict(hello="POST")


@view_config(route_name='gm', renderer='json',request_method="PUT")
def put(request):
    return dict(hello="PUT")


@view_config(route_name='gm', renderer='json',request_method="DELETE")
def delete(request):
    return dict(hello="DELETE")

GET / POST有效，但PUT，删除没有！

import { Injectable } from '@angular/core';
import {Http} from "@angular/http";

import "rxjs/add/operator/map"

@Injectable()
export class AppService {
  baseUrl : string = "http://10.0.0.34:8880"
  constructor(public http:Http) { }

  getData(url) {
    console.log('hi');
    let full_url= this.baseUrl + url;
    return this.http.get(full_url)
      .map(response => response.json());
  }
  postData(url) {
    console.log('hello');
    let full_url= this.baseUrl + url;
    return this.http.post(full_url,null)
      .map(response => response.json());
  }
  putData(url) {
    console.log('hello');
    let full_url= this.baseUrl + url;
    return this.http.put(full_url,null)
      .map(response => response.json());
  }
  deleteData(url) {
    console.log('hello');
    let full_url= this.baseUrl + url;
    return this.http.delete(full_url)
      .map(response => response.json());
  }

}

解决了谢谢

@view_config (route_name='gm', renderer='json',request_method="OPTIONS")
    def options(context, request):
        request.response.headers.update({
            'Access-Control-Allow-Origin': '*',
            'Access-Control-Allow-Methods': 'POST,GET,DELETE,PUT,OPTIONS',
            'Access-Control-Allow-Headers': 'Origin, Content-Type, Accept, Authorization',
            'Access-Control-Allow-Credentials': 'true',
            'Access-Control-Max-Age': '1728000',
        })
        return dict()

金字塔CORS不提供PUT AND DELETE
