def parser = new JsonSlurper()
def jsonResp = parser.parseText(json)
println jsonResp

错误：

groovy.json.JsonException: expecting '}' or ',' but got current char '+' with an int value of 43

The current character read is '+' with an int value of 43
expecting '}' or ',' but got current char '+' with an int value of 43
line number 1
index number 255

让我们指出问题：

import groovy.json.JsonSlurper 

def json ='''
{
    "branchFilters": "[\"+refs/heads/*\"]"
}
'''

def parser = new JsonSlurper()
def jsonResp = parser.parseText(json)
println jsonResp

错误：

groovy.json.JsonException: expecting '}' or ',' but got current char '+' with an int value of 43

The current character read is '+' with an int value of 43
expecting '}' or ',' but got current char '+' with an int value of 43

Answer 1

您可以使用不需要转义反斜杠的所谓美元斜线字符串

import groovy.json.JsonSlurper 
def json = $/
{
    "branchFilters": "[\"+refs/heads/*\"]"
}
/$
println json

def parser = new JsonSlurper()
def jsonResp = parser.parseText(json)
println jsonResp

Answer 2

尝试println变量json，你会发现两个反斜杠都消失了，这导致了一个无效的JSON字符串： {“branchFilters”：“[”+ refs / heads / *“]”}

如果需要将JSON字符串直接粘贴到代码中，则必须转义每个反斜杠。如果从其他来源（如文件或http请求）获取String，则不适用。

import groovy.json.JsonSlurper 

def json ='''
{
    "branchFilters": "[\\"+refs/heads/*\\"]"
}
'''
println json // "branchFilters": "[\"+refs/heads/*\"]"
def parser = new JsonSlurper()
def jsonResp = parser.parseText(json)
println jsonResp // [branchFilters:["+refs/heads/*"]]
