Question

我正在使用Prestashop网络服务。我正在尝试向API发送PUT（更新）请求，但没有运气。我的请求似乎是以'错误'的方式设置的（即不是服务器期望的方式）因为Prestashop是开源的，所以我看了一下源代码，特别是当它收到PUT请求时执行以下操作（我不编写php代码）：

$input_xml = null;
// if a XML is in PUT or in POST
if (($_SERVER['REQUEST_METHOD'] == 'PUT') || ($_SERVER['REQUEST_METHOD'] == 'POST')) {
    $putresource = fopen("php://input", "r");
    while ($putData = fread($putresource, 1024)) {
        $input_xml .= $putData;
    }
fclose($putresource);
  }
if (isset($input_xml) && strncmp($input_xml, 'xml=', 4) == 0) {
    $input_xml = substr($input_xml, 4);
}

从上面的代码中我了解到我的数据看起来应该是这样的：xml=<data><here></here></data>但我不知道在哪里放这个，它应该在请求体中还是嵌入在url中？当您使用Content-Type = text/xml发送请求时隐含“xml =”？我确实尝试了不同的请求组合，但仍然遇到相同的404错误。我试过这个：

let updateOrderState (orderId:int64) (stateId:int64) (credentials:AuthInfo) = 
    // url looks like this: http://www.webstoreexample.com/entity/id
    let auth = BasicAuth credentials.Key ""
    let orderApi = credentials.Api + "/orders/" + orderId.ToString();
    let orderAsXml = Http.RequestString(orderApi, httpMethod = "GET", headers = [auth])
    let xml = Order.Parse(orderAsXml).XElement // at this point, I have the data
    xml.Element(XName.Get("order")).Element(XName.Get("current_state")).SetValue(stateId) // field 'current_state' gets modified
    let xmlData = xml.ToString()
    // HERE the put request
    Http.RequestString(url = credentials.Api + "/orders", 
                       headers = [ auth; 
                                   "Content-Type","text/xml" ],         
                       httpMethod= HttpMethod.Put,
                       body= HttpRequestBody.TextRequest(xmlData))

PUT请求的变化也不起作用，我在此处将请求正文从TextRequest更改为FormValues：

Http.RequestString(url = credentials.Api + "/orders", 
                   headers = [ auth; 
                               "Content-Type","text/xml" ],         
                   httpMethod= HttpMethod.Put,
                   body= HttpRequestBody.FormValues ["xml", xmlData]) // xml=xmlData

我尝试的另一件事是将id添加到网址（即使是文档，他们说这不是必需的）：

Http.RequestString(url = credentials.Api + "/order/" + orderId.ToString(), // added the id to the url
                   headers = [ auth; 
                               "Content-Type","text/xml" ],         
                   httpMethod= HttpMethod.Put,
                   body= HttpRequestBody.FormValues ["xml", xmlData]) // xml=xmlData

具体来说，我要更新订单的current_state节点的值。获取数据并对其进行修改可以按预期工作，但发送修改后的数据似乎不起作用，我仍然收到404: Not found错误

对此的任何帮助都会非常感激！

好的，我刚刚用评论中给出的library和example对其进行了测试，我也使用相同的正面结果重复使用CURL的相同请求，因此没有特定的PHP语言。我认为你需要在你的应用程序中重复相同的Headers / Body。
