我对angular2非常陌生,我试图通过http标头传递的auth凭据向本地API发出REST请求;我得到了以下代码:
let headers = new Headers();
headers.append('Accept', 'application/json')
headers.append('Content-Type', 'application/json');
headers.append('Authorization', 'Basic ' + btoa(user + ":" + password));
let options = new RequestOptions({ headers: headers, withCredentials: true });
return this.http.get("http://localhost:8080/api/test-credentials", options);
但我得到401:未经授权。 如果我尝试使用POSTMAN一切正常,生成的base64编码令牌是相同的,这是请求的对象:
[
"http://localhost:8080/api/test-credentials",
{
"method":null,
"headers":{
"Accept":[
"application/json"],
"Content-Type":["application/json"],
"Authorization":["Basic dXNlcjpwYXNzd29yZA=="]
},
"body":null,
"url":null,
"search":null,
"withCredentials":true,
"responseType":null
}
]
答案 0 :(得分:2)
使用以下身份验证发出请求:
public getRequestWithBasicAuth(url: string, data): any {
let headers = new Headers();
headers.append("Content-Type", "application/json");
headers.append("Authorization", "Basic " + data);
let requestoptions = new RequestOptions({
method: RequestMethod.Get,
url: url,
headers: headers
});
return this.http.request(new Request(requestoptions))
.map((res: Response) => {
let jsonObj: any;
if (res.status === 204) {
jsonObj = null;
}
else if (res.status === 500) {
jsonObj = null;
}
else if (res.status === 200) {
jsonObj = res.json()
}
return [{ status: res.status, json: jsonObj }]
})
.catch(error => {
return Observable.throw(error);
});
}
然后在提交登录调用上面的函数:
onLogin(formData) {
let url = this.global_service.base_path + 'something...';
let data = btoa(formData.email.toLowerCase() + ':' + formData.password);
this.global_service.getRequestWithBasicAuth(url, data)
.subscribe(res => {
if (res[0].status == 200) {
// Do what you want after login..
}
}
}
