将curl POST与bash脚本函数中定义的变量一起使用

Question

当我回声时，我得到了它，当我将其输入到终端时，它将运行

curl -i \
-H "Accept: application/json" \
-H "Content-Type:application/json" \
-X POST --data '{"account":{"email":"[e-mail]","screenName":"akdgdtk","type":"NIKE","passwordSettings":{"password":"Starwars1","passwordConfirm":"Starwars1"}},"firstName":"Test","lastName":"User","middleName":"ObiWan","locale":"en_US","registrationSiteId":"520","receiveEmail":"false","dateOfBirth":"1984-12-25","mobileNumber":"9175555555","gender":"male","fuelActivationDate":"2010-10-22","postalCode":"10022","country":"US","city":"Beverton","state":"OR","bio":"This is a test user","jpFirstNameKana":"unsure","jpLastNameKana":"ofthis","height":"80","weight":"175","distanceUnit":"MILES","weightUnit":"POUNDS","heightUnit":"FT/INCHES"}' https://xxx:[e-mail]/xxxxx/xxxx/xxxx

但是在bash脚本文件中运行时，出现此错误

curl: (6) Could not resolve host: application; nodename nor servname provided, or not known
curl: (6) Could not resolve host: is; nodename nor servname provided, or not known
curl: (6) Could not resolve host: a; nodename nor servname provided, or not known
curl: (6) Could not resolve host: test; nodename nor servname provided, or not known
curl: (3) [globbing] unmatched close brace/bracket at pos 158

这是文件中的代码

curl -i \
-H '"'Accept: application/json'"' \
-H '"'Content-Type:application/json'"' \
-X POST --data "'"'{"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"}'"'" "https://xxx:[e-mail]/xxxxx/xxxx/xxxx"

我认为引号存在问题，但是我经常玩引号，并且遇到了类似的错误。在实际脚本中，所有变量都使用不同的功能定义

您无需传递引号将自定义标头括起来即可卷曲。另外，data应在参数中间加上变量。

首先，编写一个函数来生成脚本的发布数据。这使您免于有关shell引用的种种麻烦，并且使读取维护脚本比在curl调用行中输入post数据更容易，如您的尝试：

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
}

然后很容易在curl的调用中使用该函数：

curl -i \
-H "Accept: application/json" \
-H "Content-Type:application/json" \
-X POST --data "$(generate_post_data)" "https://xxx:[e-mail]/xxxxx/xxxx/xxxx"

就是说，这里有一些关于shell引用规则的说明：

-H参数中的双引号（如所示-H "foo bar"）告诉bash将内部内容作为单个参数保留（即使它包含空格）。

--data参数中的单引号（如中的--data 'foo bar'）执行相同的操作，只是它们逐字传递所有文本（包括双引号和美元符号）。

要在单引号引起的文本中间插入变量，您必须结束单引号，然后将其与双引号变量连接，然后重新打开单引号以继续文本：'foo bar'"$variable"'more foo'。
