我已经完成了该项目的较难部分，但是cURL似乎不想合作。我不断收到来自服务器的空答复（可能没有POSTFIELDS数据正在发送）或API特定错误A-19，这是格式错误或类型错误的请求。如果我使用硬编码的字符串而不是必需的变量发送请求，则该请求可以正常工作。
我通过使用API文档提供的示例请求格式以及API文档提供的特定测试数据开始了该过程。在构建演示测试以开始解析数据的困难部分时，我使用了POSTMAN。一旦找出响应的所有解析内容，我就简单地从Postman那里获取了cURL代码，并对其进行了测试，然后就可以了。当我开始用POST设置的变量（例如，使用$_REQUEST[fname]）替换诸如名称，姓氏等之类的变量时，出现了我的问题。我尝试使用下面的变量分配以及原始POST数据变量。 $output上的echo完全按预期工作，因此我很肯定POST值是可访问的。
$state = $_REQUEST[state];
$type = $_REQUEST[type];
$street = $_REQUEST[street];
$city = $_REQUEST[city];
$zipcode = $_REQUEST[zipcode];
$fname = $_REQUEST[fname];
$lname = $_REQUEST[lname];
$email = $_REQUEST[email];
$phone = $_REQUEST[phone];
$estCreditScore = $_REQUEST[estCreditScore];
$estLoanAmount = $_REQUEST[estLoanAmount];
$estDownPayment = $_REQUEST[estDownPayment];
$monthlyIncome = $_REQUEST[monthlyIncome];
$ssn = $_REQUEST[ssn];

答案 0 :(得分：0)
您说要在Content-Type标头中发送XML，但是随后将其发送为纯文本（通过htmlspecialchars()运行XML时得到的文本。）实际上，我们使用所有这些变量，创建并转义它们。尽管您确实应该使用适当的工具来构建XML，但是使用Heredoc块将使事情变得更容易。不需要大多数标题，但是如果您确实想滚动自己的“ Content-Length”标题，则需要在其中放置正确的值。
