使用變量的cURL POST請求

Question

我想設置一個基本代碼，將一些客戶插入到我們的客戶支持軟件中，而無需手動進行每一項操作。 當我將變量引入代碼時，我似乎遇到了問題。

此代碼：

#!/bin/sh 
curl https://yoursite.desk.com/api/v2/customers \ 
-u username:password \ 
-X POST \ 
-H "Accept: application/json" \ 
-H "Content-Type: application/json" \ 
-d '{ 
    "first_name":"John", 
    "last_name":"Doe", 
    "phone_numbers": 
     [ 
     { 
      "type":"Other", 
      "value":"5555555555" 
     } 
     ], 
    "emails": 
     [ 
     { 
      "type": "other", 
      "value":"johndoe@email.com 
     } 
     ], 
    "custom_fields": 
     { 
      "field_a":"12345" 
     } 
    }' 

該代碼始終返回錯誤「無效的JSON」

#!/bin/sh 

first=John 
last=Doe 
phone=5555555555 
phone_type=other 
email=johndoe@email.com 
email_type=other 
id=12345 

curl https://yoursite.desk.com/api/v2/customers \ 
-u username:password \ 
-X POST \ 
-H "Accept: application/json" \ 
-H "Content-Type: application/json" \ 
-d '{ 
    "first_name":'"$first"', 
    "last_name":'"$last"', 
    "phone_numbers": 
     [ 
     { 
      "type":'"$phone_type"', 
      "value":'"$phone"' 
     } 
     ], 
    "emails": 
     [ 
     { 
      "type":'"$email_type"', 
      "value":'"$email"' 
     } 
     ], 
    "custom_fields": 
     { 
      "field_a":'"$id"' 
     } 
    }' 

對於它的價值，因爲我已經調整了代碼偶爾錯誤代碼會顯示「emails」：「value」:(無效）和「phone_numbers」：「value」:(無效）

Answer 1

在你的例子中"$first"擴展爲John（雙引號丟失）。其他擴展也是如此。包括在命令中的單引號部分所需的雙引號（但保留周圍的變量擴展雙引號）：

#!/bin/sh 

first=John 
last=Doe 
phone=5555555555 
phone_type=other 
email=johndoe@email.com 
email_type=other 
id=12345 

curl https://yoursite.desk.com/api/v2/customers \ 
-u username:password \ 
-X POST \ 
-H "Accept: application/json" \ 
-H "Content-Type: application/json" \ 
-d '{ 
    "first_name":"'"$first"'", 
    "last_name":"'"$last"'", 
    "phone_numbers": 
     [ 
     { 
      "type":"'"$phone_type"'", 
      "value":"'"$phone"'" 
     } 
     ], 
    "emails": 
     [ 
     { 
      "type":"'"$email_type"'", 
      "value":"'"$email"'" 
     } 
     ], 
    "custom_fields": 
     { 
      "field_a":"'"$id"'" 
     } 
    }'
