這篇文章主要介紹了nginx proxy_buffer_size解決后端服務(wù)傳輸數(shù)據(jù)過多,header過大問題,具有很好的參考價值,希望對大家有所幫助,如有錯誤或未考慮完全的地方,望不吝賜教

nginx proxy_buffer_size解決后端服務(wù)傳輸數(shù)據(jù)過多,其實是header過大

這三個參數(shù)已設(shè)置就搞定了

proxy_buffer_size 64k;
proxy_buffers   4 32k;
proxy_busy_buffers_size 64k;

本著精益求精的精神我翻了官網(wǎng)

官網(wǎng)解釋

總體來說我還是沒懂。

我把報錯信息放出來，以后用得著。

開發(fā)說nginx502了，后端訪問jesery沒問題

不行
curl -i -v "test.lebi.letv.cn/report/rest/saiku/api/query/7C53220D-A870-1FE3-9353-4A6F967F25CB/result/metadata/hierarchies/%5BDM_REC.DIM_LIVE_STATION%5D.%5BDM_REC.DIM_LIVE_STATION.LIVE_STATION_NAME%5D/levels/DM_REC.DIM_LIVE_STATION.LIVE_STATION_NAME?result=false&_=1489736122190"
可以
curl -i -v "http://10.142.165.45:8080/report/rest/saiku/api/query/7C53220D-A870-1FE3-9353-4A6F967F25CB/result/metadata/hierarchies/%5BDM_REC.DIM_LIVE_STATION%5D.%5BDM_REC.DIM_LIVE_STATION.LIVE_STATION_NAME%5D/levels/DM_REC.DIM_LIVE_STATION.LIVE_STATION_NAME?result=false&_=1489736122190"

日志對比

返回502

正常了

我測了下，返回的json數(shù)據(jù)大約1.3M，可能是返回值太大，超過了閾值，但是超過了哪個呢，比較糾結(jié)。

查看error日志得到upstream sent too big header while reading response header from upstream，說header太大了。

好好學(xué)習(xí)下header
