Question

我想在curl_setopt($ch, CURLOPT_POSTFIELDS)函数中发送一个对象(javascript对象(，我试了一些方法，但找不到合适的组合。我尝试了下面的代码，但在这一行中得到了以下错误syntex error unexpected {：curl_setopt($ch, CURLOPT_POSTFIELDS, {

我应该如何写对象？在PHP 中最好的做法是什么

这是目标示例：

{
'Key': '',
'Local': 'us',
'UniqueId': '',
'SuccessUrl': '',
'CancelUrl': '',
'CallbackUrl': '',
'PaymentType': 'regular',
'CreateInvoice': 'false',
'AdditionalText': '',
'ShowCart': 'true',
'Installments': {
Type: 'regular' , 
MinQuantity: '1',
MaxQuantity: '12'
},
'Customer': {
'Email': '[e-mail]',
'Name': 'Demo Client' ,
'PhoneNumber':  '031351315',
'Attributes': {
'HolderId':  'none' ,
'Name':  'required' ,
'PhoneNumber':  'required' ,
'Email':  'optional'
}
},
'CartItems': [{
'Amount': '10.20',
'Currency': 'usd',
'Name': 'My Item1 Name',
'Description': 'My Item description , comes below the name' , 
'Quantity': 2 ,
'Image': 'https://google.com' ,
'IsTaxFree':  'false'
}]
};

这是我尝试过的：

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://exampleurl.com/CreateSession");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, {
"Key": "1231231231231321321321321",
"Local": "us",
"UniqueId": "",
"SuccessUrl": "",
"CancelUrl": "",
"CallbackUrl": "",
"PaymentType": "regular",
"CreateInvoice": "false",
"AdditionalText": "",
"ShowCart": "true",
"Installments": {
Type: "regular" , 
MinQuantity: "1",
MaxQuantity: "12"
},
"Customer": {
"Email": "[e-mail]",
"Name": "Demo Client" ,
"PhoneNumber":  "21351135",
"Attributes": {
"HolderId":  "none" ,
"Name":  "required" ,
"PhoneNumber":  "required" ,
"Email":  "optional"
}
},
"CartItems": [{
"Amount": "10.20",
"Currency": "usd",
"Name": "My Item1 Name",
"Description": "My Item description , comes below the name" , 
"Quantity": 2 ,
"Image": "https://google.com.png" ,
"IsTaxFree":  "false"
}]
});
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
"Content-Type: application/json; charset=utf-8"
));
$response = curl_exec($ch);
curl_close($ch);
var_dump($response);

Answer 1

这是一个字符串，所以应该用引号括起来：

curl_setopt($ch, CURLOPT_POSTFIELDS, "{
"Key": "1231231231231321321321321",
"Local": "us",
"UniqueId": "",
"SuccessUrl": "",
"CancelUrl": "",
"CallbackUrl": "",
"PaymentType": "regular",
"CreateInvoice": "false",
"AdditionalText": "",
"ShowCart": "true",
"Installments": {
Type: "regular" ,
MinQuantity: "1",
MaxQuantity: "12"
},
"Customer": {
"Email": "[e-mail]",
"Name": "Demo Client" ,
"PhoneNumber":  "21351135",
"Attributes": {
"HolderId":  "none" ,
"Name":  "required" ,
"PhoneNumber":  "required" ,
"Email":  "optional"
}
},
"CartItems": [{
"Amount": "10.20",
"Currency": "usd",
"Name": "My Item1 Name",
"Description": "My Item description , comes below the name" ,
"Quantity": 2 ,
"Image": "https://google.com.png" ,
"IsTaxFree":  "false"
}]
}");

将JSON数据存储在一个变量中，然后简单地发布。

<?php
$ch = curl_init();
$jsonPost = `{
"Key": "1231231231231321321321321",
"Local": "us",
"UniqueId": "",
"SuccessUrl": "",
"CancelUrl": "",
"CallbackUrl": "",
"PaymentType": "regular",
"CreateInvoice": "false",
"AdditionalText": "",
"ShowCart": "true",
"Installments": {
Type: "regular" , 
MinQuantity: "1",
MaxQuantity: "12"
},
"Customer": {
"Email": "[e-mail]",
"Name": "Demo Client" ,
"PhoneNumber":  "21351135",
"Attributes": {
"HolderId":  "none" ,
"Name":  "required" ,
"PhoneNumber":  "required" ,
"Email":  "optional"
}
},
"CartItems": [{
"Amount": "10.20",
"Currency": "usd",
"Name": "My Item1 Name",
"Description": "My Item description , comes below the name" , 
"Quantity": 2 ,
"Image": "https://google.com.png" ,
"IsTaxFree":  "false"
}]
}`;
curl_setopt($ch, CURLOPT_URL, "https://exampleurl.com/CreateSession");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonPost);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
"Content-Type: application/json; charset=utf-8"
));
$response = curl_exec($ch);
curl_close($ch);
var_dump($response);
?>

syntex意外错误｛

因为您缺少" "或' '，

试试这个

curl_setopt($ch, CURLOPT_POSTFIELDS, "{
'Key': '',
'Local': 'us',
'UniqueId': '',
'SuccessUrl': '',
'CancelUrl': '',
'CallbackUrl': '',
'PaymentType': 'regular',
'CreateInvoice': 'false',
'AdditionalText': '',
'ShowCart': 'true',
'Installments': {
Type: 'regular' , 
MinQuantity: '1',
MaxQuantity: '12'
},
'Customer': {
'Email': '[e-mail]',
'Name': 'Demo Client' ,
'PhoneNumber':  '031351315',
'Attributes': {
'HolderId':  'none' ,
'Name':  'required' ,
'PhoneNumber':  'required' ,
'Email':  'optional'
}
},
'CartItems': [{
'Amount': '10.20',
'Currency': 'usd',
'Name': 'My Item1 Name',
'Description': 'My Item description , comes below the name' , 
'Quantity': 2 ,
'Image': 'https://google.com' ,
'IsTaxFree':  'false'
}]
};");

我想解释一下，但是我的英语不好，对不起。
