使用 Groovy 的 HTTPBuilder，如何设置超时

Question

我正在尝试使用 Groovy HTTPBuilder 设置连接超时，但我一直找不到方法。

使用简单的 ol' URL 很简单：

def client = new URL("https://search.yahoo.com/search?q=foobar")
def result = client.getText( readTimeout: 1 )

这会引发 SocketTimeoutException，但这并不是我想要的。由于各种原因，我宁愿使用 HTTPBuilder 或更好的 RESTClient。

这确实有效：

    def client = new HTTPBuilder()
    def result = client.request("https://search.yahoo.com/", Method.GET, "*/*") { HttpRequest request ->
        uri.path = "search"
        uri.query = [q: "foobar"]
        request.getParams().setParameter("http.socket.timeout", 1);
    }

但是 request.getParams() 已被弃用。

我这辈子都找不到将正确的 RequestConfig 注入构建器的方法。

Answer 1

从 JavaDoc 看来，您是通过使用 AsyncHttpBuilder 来实现的？ class 扩展了 HTTPBuilder 并且它有一个 setTimeout(int) 方法。

看看这个：http://www.kellyrob99.com/blog/2013/02/10/groovy-and-http/ According to that, it appears you might be able to follow the advice here to get a timeout on your connection:

试试这个，我用的是 0.7.1:

import groovyx.net.http.HTTPBuilder
import org.apache.http.client.config.RequestConfig
import org.apache.http.config.SocketConfig
import org.apache.http.conn.ConnectTimeoutException
import org.apache.http.impl.client.HttpClients

def timeout = 10000 // millis
SocketConfig sc = SocketConfig.custom().setSoTimeout(timeout).build()
RequestConfig rc = RequestConfig.custom().setConnectTimeout(timeout).setSocketTimeout(timeout).build()
def hc = HttpClients.custom().setDefaultSocketConfig(sc).setDefaultRequestConfig(rc).build()        
def http = new HTTPBuilder('https://search.yahoo.com/')
http.client = hc

http.get(path:'/search')

我是这样用的

def timeOut = 10000
HTTPBuilder http = new HTTPBuilder('http://url.com')
http.client.params.setParameter('http.connection.timeout', new Integer(timeOut))
http.client.params.setParameter('http.socket.timeout', new Integer(timeOut))

纯 HTTPBuilder：

import org.apache.http.client.config.RequestConfig

def TIMEOUT = 10000
def defaultRequestConfig = RequestConfig.custom()
        .setConnectionRequestTimeout(TIMEOUT)
        .setConnectTimeout(TIMEOUT)
        .setSocketTimeout(TIMEOUT)
        .build()
def client = new HTTPBuilder("uri")
client.setClient(HttpClients.custom().setDefaultRequestConfig(defaultRequestConfig).build())

RESTClient 应有尽有：

import org.apache.http.auth.AuthScope
import org.apache.http.auth.UsernamePasswordCredentials
import org.apache.http.client.config.RequestConfig
import org.apache.http.conn.ssl.NoopHostnameVerifier
import org.apache.http.conn.ssl.SSLConnectionSocketFactory
import org.apache.http.conn.ssl.TrustSelfSignedStrategy
import org.apache.http.impl.client.BasicCredentialsProvider
import org.apache.http.impl.client.HttpClients
import org.apache.http.impl.conn.PoolingHttpClientConnectionManager
import org.apache.http.ssl.SSLContextBuilder

def restClient = new RESTClient("hostname")

//timeout
def TIMEOUT = 5000
def defaultRequestConfig = RequestConfig.custom()
        .setConnectionRequestTimeout(TIMEOUT)
        .setConnectTimeout(TIMEOUT)
        .setSocketTimeout(TIMEOUT)
        .build()

//basic user/password authentication
def credentials = new UsernamePasswordCredentials("admin", "password")
def credentialsProvider = new BasicCredentialsProvider()
credentialsProvider.setCredentials(AuthScope.ANY, credentials)

//set ssl trust all, no ssl exceptions
def sslContext = new SSLContextBuilder().loadTrustMaterial(null, TrustSelfSignedStrategy.INSTANCE).build()
def sslSocketFactory = new SSLConnectionSocketFactory(sslContext, NoopHostnameVerifier.INSTANCE)

//multithreaded connection manager
def multithreadedConnectionManager = new PoolingHttpClientConnectionManager()

//build client with all this stuff
restClient.setClient(HttpClients.custom()
        .setConnectionManager(multithreadedConnectionManager)
        .setDefaultCredentialsProvider(credentialsProvider)
        .setDefaultRequestConfig(defaultRequestConfig)
        .setSSLSocketFactory(sslSocketFactory)
        .build())
