[Jmeter併發報錯解決方案]org.apache.http.NoHttpResponseException: 10.0.4.147:8000 failed to respond

 

背景：公司模型框架是Nginx+uwsgi+Django+nginx，一開始使用Jmeter進行高併發請求測試，發現成功率只有50%，換用postman，成功率100%，代碼進行高併發同樣不會報錯。

問題：

Jmeter進行高併發，第一個接口成功，第二個失敗，第三個又成功，第四個失敗。。。依次類推，保持50%的失敗率，失敗報錯以下：

org.apache.http.NoHttpResponseException: **.**.**.***:***** failed to respond at org.apache.http.impl.conn.DefaultHttpResponseParser.parseHead(DefaultHttpResponseParser.java:141) at org.apache.http.impl.conn.DefaultHttpResponseParser.parseHead(DefaultHttpResponseParser.java:56) at org.apache.http.impl.io.AbstractMessageParser.parse(AbstractMessageParser.java:259) at org.apache.http.impl.AbstractHttpClientConnection.receiveResponseHeader(AbstractHttpClientConnection.java:281) at org.apache.http.impl.conn.DefaultClientConnection.receiveResponseHeader(DefaultClientConnection.java:257) at org.apache.jmeter.protocol.http.sampler.hc.ManagedClientConnectionImpl.receiveResponseHeader(ManagedClientConnectionImpl.java:199) at org.apache.jmeter.protocol.http.sampler.MeasuringConnectionManager$MeasuredConnection.receiveResponseHeader(MeasuringConnectionManager.java:212) at org.apache.http.protocol.HttpRequestExecutor.doReceiveResponse(HttpRequestExecutor.java:273) at org.apache.http.protocol.HttpRequestExecutor.execute(HttpRequestExecutor.java:125) at org.apache.http.impl.client.DefaultRequestDirector.tryExecute(DefaultRequestDirector.java:684) at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:486) at org.apache.http.impl.client.AbstractHttpClient.doExecute(AbstractHttpClient.java:835) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:83) at org.apache.jmeter.protocol.http.sampler.HTTPHC4Impl.executeRequest(HTTPHC4Impl.java:654) at org.apache.jmeter.protocol.http.sampler.HTTPHC4Impl.sample(HTTPHC4Impl.java:413) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerProxy.sample(HTTPSamplerProxy.java:74) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.sample(HTTPSamplerBase.java:1189) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.sample(HTTPSamplerBase.java:1178) at org.apache.jmeter.threads.JMeterThread.executeSamplePackage(JMeterThread.java:491) at org.apache.jmeter.threads.JMeterThread.processSampler(JMeterThread.java:425) at org.apache.jmeter.threads.JMeterThread.run(JMeterThread.java:254) at java.lang.Thread.run(Thread.java:748)

由於模型接口是用python寫的，報錯代碼顯示java，因此一開始認爲是Jmeter的問題，換了一個工具，postman，進行併發測試，果真沒有拋錯，可是學無止境，做爲一個優秀的測試工具，不該該有這個問題啊，因此繼續挖掘解決方案。

解決方案：

取消勾選Use Keep-alive，這樣鏈接就不會複用，也就不存在空閒超時，被服務端幹掉的狀況了。

但帶來的是性能的開銷，由於tcp每次都要關閉而後重建。
