如何在 NestJS 中记录所有 Axios 外部 http 请求 [英] How to log all Axios external http requests in NestJS
问题描述
我希望能够使用完整的 url、标题等记录每个 axios 请求,但目前没有找到这样做的方法.
I want to be able to log each axios request with full url, headers, etc but currently didn't find a way to do so.
到目前为止我所做的是基于这个answer
What I did achieve so far is to writhe an Http Interceptor based on this answer
export class HttpLoggerInterceptor implements NestInterceptor {
intercept(
context: ExecutionContext,
call$: Observable<any>,
): Observable<any> {
return call$.pipe(
map(data => {
// pipe call to add / modify header(s) after remote method
const req = context.switchToHttp().getRequest();
return data;
}),
);
}
}
现在我在调试时浏览对象 req
和 context
道具,但看不到 Asios 请求 url 等.除非我错过了.
Now I browse through the objects req
and context
props on debug but could not see Asios request url, etc. Unless I missed that.
我的控制器路由(在那种情况下为 api/data
)有 N 个 http 外部调用发生,但拦截器只拦截控制器控制器调用而不是 Axios 调用.
My controller route (api/data
in that case) have N number of http external calls taking place but interceptor intercepts only controller controller call not Axios calls.
有什么想法吗?
即context
对象:
args:Array(2) [IncomingMessage, ServerResponse]
constructorRef:class AppController { … }
getRequest:() => …
getResponse:() => …
handler:data() { … }
__proto__:Object {constructor: , getClass: , getHandler: , …}
即req
:
_dumped:false
_events:Object {}
_eventsCount:0
_maxListeners:undefined
_parsedOriginalUrl:Url {protocol: null, slashes: null, auth: null, …}
_parsedUrl:Url {protocol: null, slashes: null, auth: null, …}
_readableState:ReadableState {objectMode: false, highWaterMark: 16384, buffer: BufferList, …}
baseUrl:""
body:Object {}
client:Socket {connecting: false, _hadError: false, _handle: TCP, …}
complete:true
connection:Socket {connecting: false, _hadError: false, _handle: TCP, …}
destroyed:false
fresh:false
headers:Object {accept: "application/json, text/plain, */*", user-agent: "axios/0.18.0", host: "localhost:3000", …}
host:"localhost"
hostname:"localhost"
httpVersion:"1.1"
httpVersionMajor:1
httpVersionMinor:1
ip:"::ffff:127.0.0.1"
ips:Array(0)
method:"GET"
next:function next(err) { … }
originalUrl:"/api/data"
params:Object {}
__proto__:Object {constructor: , __defineGetter__: , __defineSetter__: , …}
path:"/api/data"
protocol:"http"
query:Object {}
rawHeaders:Array(8) ["Accept", "application/json, text/plain, */*", "User-Agent", …]
rawTrailers:Array(0) []
readable:true
readableBuffer:BufferList
readableFlowing:null
readableHighWaterMark:16384
readableLength:0
res:ServerResponse {_events: Object, _eventsCount: 1, _maxListeners: undefined, …}
route:Route {path: "/api/data", stack: Array(1), methods: Object}
secure:false
socket:Socket {connecting: false, _hadError: false, _handle: TCP, …}
stale:true
statusCode:null
statusMessage:null
subdomains:Array(0)
trailers:Object {}
upgrade:false
url:"/api/data"
xhr:false
推荐答案
Nest.js-Interceptors 只处理控制器处理的请求和发出的响应.如果在处理控制器请求时使用 Axios 发出 http 请求,它们将不会被拦截器处理.
Nest.js-Interceptors only process the request handled by your controller and the response going out. If you make http requests with Axios while you handle a controller request, they won't be processed by an interceptor.
HttpService
直接通过 get axiosRef()
公开其 axios
实例.有了它,你可以添加一个 axios 拦截器
:
The HttpService
exposes its axios
instance directly via get axiosRef()
. With it, you can add an axios interceptor
:
this.httpService.axiosRef.interceptors.request.use(config => { /*...*/ return config })
例如,您可以在 的
.onModuleInit()
中执行此操作应用模块
作为替代方案,您可以创建一个 HttpService
门面,记录请求并将所有调用委托给内置的 HttpService
:
As an alternative, you can create an HttpService
facade, that logs the request and delegates all calls to the built-in HttpService
:
@Injectable()
export class MyHttpService {
private logger: Logger = new Logger(MyHttpService.name);
constructor (private httpService: HttpService) {}
public get<T = any>(url: string, config?: AxiosRequestConfig): Observable<AxiosResponse<T>> {
this.logger.log({url, config});
return this.httpService.get(url, config)
.pipe(tap(response => this.logger.log(response)));
}
// ... all the other methods you need.
}
您可以创建自己的 LoggingHttpModule
,导入内置的 HttpModule
并导出您的 MyHttpService
.
You can create your own LoggingHttpModule
that imports the built-in HttpModule
and exports your MyHttpService
.
