Question

使用Postman进行GET方法Service调用时，我得到了一个成功的响应，但是当从Angular进行相同的调用时，我得到405错误。

var token = "sdfasdfasdfasdfaerqwelruaoeuapiou"
this.contentHeader = new Headers({"Content-Type":"application/json","Authorization":"Bearer"+token});

  this.http = http;
  this.url=IES.serviceUrl+'page/'+this.pageName;
  this.http.get(this.url,{ headers: this.contentHeader }).map(res => res.json())
  .subscribe(data => {
    this.pageData = data;
    this.pageControls = this.pageData.controls;
  } , error => {
        console.log('failed');
  });

此代码在IE浏览器中运行时发送所需的“授权”标题，但无法在FF / chrome中发送标题

FF / Chrome浏览器的小提琴捕获是：

{"Message":"The requested resource does not support http method 'OPTIONS'."}

firefox或IE浏览器中的Rest Client与

类似

{"PageId":1,"PageName":"dashboard","controls":["barchart","pieChart","scatterChart"],"lists":{},"actions":{}}

注意本

中的授权标题

HTTP / 1.1 405方法不允许
