Question

对于此发布请求，我无法获得任何服务器响应：

WHERE

更新： Fiddler显示了我希望获得的服务器响应 this.httpClient .post(this.appConfigService.buildAuthorizationUrl('/logon'), data, { headers: { 'Content-Type': 'application/x-www-form-urlencoded' }, //observe: 'response', }) .toPromise() .then( (response: any) => { // not reached }, (error: any) => { // not reached } ) .catch(ex => { // not reached });成功阻止：

一个服务器响应示例：

.then

更新可能是因为标头

代替

Sec-Fetch-Site: same-site
Sec-Fetch-Mode: cors

背景：我正在将现有的angularjs应用程序迁移到angular，并使用相同的（未更改）API

Answer 1

问题是由CORS问题引起的
