jmeter报错---javax.script.ScriptException: UnicodeEncodeError: 'ascii' codec can't encode characters in position 109-111: ordinal not in range(128) in <script> at line number 3

python代码：

import json
supplyRelationResultList=vars.get("supplyRelationResultList")
log.info("supplyRelationResultList==="+str(supplyRelationResultList))

　　报错原因：最后一行中的str去掉就可以了，已经是字符串了，不需要再次转换成字符串，改为下方即可：

log.info("supplyRelationResultList==="+supplyRelationResultList)
