我正在尝试使用来自 avalara.net 的 API 来获取销售税数据，他们的 API 文档列出了基本上是一行代码，其中包含 JSON 格式的长字符串，用于通过 cURL 连接到他们的 API；我不熟悉这种单字符串样式，并试图将其转换为遵循 php 手册样式的格式，例如通过 curl_setopt() 设置选项而不是像 -u 和 -d 这样的内联命令，但我不是到达任何地方。

我已经看过php - 对 php 实施 curl 命令行，尝试但出现错误并添加了他们的解决方案 - 因为我没有收到任何错误消息我不知道我的问题是否相同，但似乎不会伤害添加 CURLOPT_FOLLOWLOCATION。似乎没有任何区别。

我还查看了 php 代码中的 convert curl line 命令，但它没有帮助，因为我的代码中已经有 curl_exec() 并且一直在阅读 php 手册页。

他们的代码可以在https://github.com/avadev/AvaTax-Calc-REST-cURL/blob/master/tax-get-POST.txt看到，相关部分是：

curl -u <AccountNumber>:<LicenseKey> -H "Content-Type: text/json" -d '{
--long string of data omitted; see link above for full data--
}' "https://development.avalara.net/1.0/tax/get"

我做了一些研究，发现 -u 是用户名/密码，-H 是一个特殊的标头，-d 是要发送的数据......所以这是我放在一起的：

// Identify the target URL
$url = 'https://development.avalara.net/1.0/tax/get';

// Start the process
$curl = curl_init($url);

// Tell cURL to fail if an error occurs
curl_setopt($curl, CURLOPT_FAILONERROR, 1);

// Allow for redirects; we don't know how avalara might route requests
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);

// Assign the returned data to a variable
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

// Set the timeout
curl_setopt($curl, CURLOPT_TIMEOUT, 5);

// Make sure to use POST method
curl_setopt($curl, CURLOPT_POST, 1);

// Set cURL to use a login:password for access
curl_setopt($curl, CURLOPT_USERPWD, "[1100033004]:[1FC8AED1543C699B]");

// Add some custom header info
curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-type: text/json'));

// Use Heredoc syntax to encapsulate data, to avoid having to escape a million quotes
$data = <<<EOD

}
]
}
EOD;
// That EOD ends the encapsulation via Heredoc syntax
// Note that the actual code does not indent the closing of Heredoc; only indented for stack overflow code view

// Set the POST data
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);

// Execute the transaction
$r = curl_exec($curl);

// Close the connection
curl_close($curl);

// Print the results for debugging
print_r($r);

但是，当我尝试查看网页时，我什么也看不到 - 没有错误消息，没有结果，什么都没有。

我已经在 stackoverflow 和 php 手册中查看了其他一些帖子 - 我现在不确定如何调试它，因为我没有收到任何错误消息。任何想法将不胜感激。

这是一个演示示例，用于演示在 PHP 中使用 API，这可以帮助您将一些数据发布到 API

$url = '<your url here>';
$curl = curl_init($url);

$data_string = '[
    {
        "FirstName": "Value"
    },
    {
        "EmailAddress": "Value"
    },
    {
        "Phone": "Value"
    }
]';

    curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_HEADER, 0);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $data_string);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($curl, CURLOPT_HTTPHEADER, array(
                                                'Content-Type:application/json',
                                                'Content-Length:'.strlen($data_string)

                                            ));

    $json_response = curl_exec($curl);
    $curl_errorno = curl_errno($curl);
    $status = curl_getinfo($curl, CURLINFO_HTTP_CODE);

    if ($status) {
        echo 'Status is 200 OK! ';
    }else{
        echo "Sorry Something went wrong. Please retry!";
        curl_close($curl);
    }

找出对您有帮助的状态码。 编辑

这将是你的价值

$data_string=
'{

            "Qty": 1,
            "Amount": 100
        }
    ]
}'

回答 像这样从这条线上移除大括号

curl_setopt($curl, CURLOPT_USERPWD, "1100033004:1FC8AED1543C699B");
