几年之后，如果你使用eval或backtick替换，这可能会帮助到一些人:

postDataJson="{\"guid\":\"$guid\",\"auth_token\":\"$token\"}"

使用sed从响应的开头和结尾去掉引号

$(curl --silent -H "Content-Type: application/json" https://${target_host}/runs/get-work -d ${postDataJson} | sed -e 's/^"//' -e 's/"$//')

以下是我从下面的回答中得到的建议:

export BASH_VARIABLE="[1,2,3]"
curl http://localhost:8080/path -d "$(cat <<EOF
{
  "name": $BASH_VARIABLE,
  "something": [
    "value1",
    "value2",
    "value3"
  ]
}
EOF
)" -H 'Content-Type: application/json'

现有的答案指出curl可以从文件中发布数据，并使用heredocs来避免过多的引号转义，并清楚地将JSON分离到新的行。然而，不需要定义函数或从cat获取输出，因为curl可以发布来自标准输入的数据。我觉得这个表格很有可读性:

curl -X POST -H 'Content-Type:application/json' --data '$@-' ${API_URL} << EOF
{
  "account": {
    "email": "$email",
    "screenName": "$screenName",
    "type": "$theType",
    "passwordSettings": {
      "password": "$password",
      "passwordConfirm": "$password"
    }
  },
  "firstName": "$firstName",
  "lastName": "$lastName",
  "middleName": "$middleName",
  "locale": "$locale",
  "registrationSiteId": "$registrationSiteId",
  "receiveEmail": "$receiveEmail",
  "dateOfBirth": "$dob",
  "mobileNumber": "$mobileNumber",
  "gender": "$gender",
  "fuelActivationDate": "$fuelActivationDate",
  "postalCode": "$postalCode",
  "country": "$country",
  "city": "$city",
  "state": "$state",
  "bio": "$bio",
  "jpFirstNameKana": "$jpFirstNameKana",
  "jpLastNameKana": "$jpLastNameKana",
  "height": "$height",
  "weight": "$weight",
  "distanceUnit": "MILES",
  "weightUnit": "POUNDS",
  "heightUnit": "FT/INCHES"
}
EOF

使用https://httpbin.org/和内联bash脚本测试的解决方案 1. 对于没有空格的变量，即1: 只需添加'之前和之后$变量替换所需 字符串

for i in {1..3}; do \
  curl -X POST -H "Content-Type: application/json" -d \
    '{"number":"'$i'"}' "https://httpbin.org/post"; \
done

2. 对于带空格的输入: 用额外的“即”来包装变量。“el”:

declare -a arr=("el a" "el b" "el c"); for i in "${arr[@]}"; do \
  curl -X POST -H "Content-Type: application/json" -d \
    '{"elem":"'"$i"'"}' "https://httpbin.org/post"; \
done

哇工作:)

乔可能会帮忙:

$ export A=this B=that C=foo D=bar
$ jo -p a=$A b=$B nested=$(jo c=$C d=$D)
{
   "a": "this",
   "b": "that",
   "nested": {
      "c": "foo",
      "d": "bar"
   }
}
