您不需要将包含自定义标头的引号传递给curl。另外，数据参数中间的变量应该加引号。

首先，编写一个生成脚本post数据的函数。这让你避免了各种关于shell引用的麻烦，并且比在curl的调用行中输入post数据更容易阅读和维护脚本:

generate_post_data()
{
  cat <<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
}

然后，在调用curl时很容易使用该函数:

curl -i \
-H "Accept: application/json" \
-H "Content-Type:application/json" \
-X POST --data "$(generate_post_data)" "https://xxx:xxxxx@xxxx-www.xxxxx.com/xxxxx/xxxx/xxxx"

也就是说，这里有一些关于shell引用规则的澄清:

-H参数中的双引号(如-H "foo bar")告诉bash将其中的内容保留为单个参数(即使它包含空格)。

——data参数中的单引号(如——data 'foo bar')执行相同的操作，只不过它们逐字传递所有文本(包括双引号字符和美元符号)。

要在单引号文本中间插入一个变量，您必须结束单引号，然后与双引号变量连接，并重新打开单引号以继续文本:'foo bar'"$variable"'more foo'。

这个脚本将使用指定的JSON主体向指定的URL发送POST请求，并将服务器的响应输出到控制台:

#!/bin/bash

# Set the URL to send the request to
url='http://example.com/endpoint'

# Set the JSON body of the request
json_data='{"key1": "value1", "key2": "value2"}'

# Make the POST request with the JSON body
response=$(curl -X POST -H "Content-Type: application/json" -d "$json_data" "$url")

echo "Response from server: $response"

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:)

工作很好，刚刚创建了post_data函数，并在shell调用中调用它。

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 ${postDataJson} | sed -e 's/^"//' -e 's/"$//')
