我目前正在使用以下代码:

<?php
/* Pre-requisite: Download the required PHP OAuth class from http://oauth.googlecode.com/svn/code/php/OAuth.php. This is used below */
require("OAuth.php");
$url = "https://yboss.yahooapis.com/geo/placespotter";
$cc_key = "MY_KEY";
$cc_secret = "MY_SECRET";
$text = "EYES ON LONDON Electric night in 100-meter dash";

$args = array();
$args["documentType"] = urlencode("text/plain");
$args["documentContent"] = urlencode($text);

$consumer = new OAuthConsumer($cc_key, $cc_secret);
$request = OAuthRequest::from_consumer_and_token($consumer, NULL,"POST", $url,$args);
$request->sign_request(new OAuthSignatureMethod_HMAC_SHA1(), $consumer, NULL);
$url = sprintf("%s?%s", $url, OAuthUtil::build_http_query($args));
$ch = curl_init();
$headers = array($request->to_header());//.',Content-Length: '.strlen($text));

//print_r($headers.',Content-Length: '.strlen($text));

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
// somehow this line is not solving the issue
// curl_setopt($ch,CURLOPT_HTTPHEADER,array('Content-Length:'.strlen($text)));
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$rsp = curl_exec($ch);
print_r($rsp);
//echo "======= ENDING";
?>

使用我自己的访问 key 和所有的 OAuth.php 库。

不知何故，我不断收到 Content-Length 未定义错误。

如果我尝试像这样定义 Content-Length(基于在 StackOverFlow 上看到的一些答案:

curl_setopt($ch,CURLOPT_HTTPHEADER,array('Content-Length:'.strlen($text)));

我没有收到任何回复。

请问如何解决这个问题？

谢谢!

我已经根据@alexblex 的评论更新了我的代码

    <?php
/* Pre-requisite: Download the required PHP OAuth class from http://oauth.googlecode.com/svn/code/php/OAuth.php. This is used below */
require("OAuth.php");
$url = "https://yboss.yahooapis.com/geo/placespotter";
$cc_key = "MY_KEY";
$cc_secret = "MY_SECRET";
$text = "EYES ON LONDON Electric from Singapore Raffles Place";
$args = array();
$args["documentType"] = urlencode("text/plain");
$args["documentContent"] = urlencode($text);
$args["outputType"] = "json";
$consumer = new OAuthConsumer($cc_key, $cc_secret);
$request = OAuthRequest::from_consumer_and_token($consumer, NULL,"PUT", $url, $args);
$request->sign_request(new OAuthSignatureMethod_HMAC_SHA1(), $consumer, NULL);
$url = sprintf("%s?%s", $url, OAuthUtil::build_http_query($args));
$ch = curl_init();
$headers = array($request->to_header());//.',Content-Length: '.strlen($text));
//$headers = array($request->to_header().',Content-Length="'.strlen($text).'"');
//$headers = array($request->to_header().',Content-Length: 277');
print_r($headers);
//print_r($headers.',Content-Length: '.strlen($text));
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, $request->to_postdata());
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$rsp = curl_exec($ch);
echo "\n\n\n\n";
var_dump($rsp);
//print_r($rsp);
?>

目前，这个新代码返回一个

{"bossresponse":{"responsecode":"500","reason":"non 200 status code from backend: 415"}

错误。

最佳答案

您没有发送 POST 数据，因此没有发送 Content-Length。要发出正确的 curl 请求，您需要指定要发送的数据。在您的情况下，它可能是:

curl_setopt($ch, CURLOPT_POSTFIELDS, $request->to_postdata());

如果 它应该是一个 POST 请求。 PlaceSpotter docs阅读:

The PlaceSpotter Web service supports only the HTTP PUT method. Other HTTP methods are not supported.

所以我认为它应该是 PUT 方法:

$request = OAuthRequest::from_consumer_and_token($consumer, NULL,"PUT", $url,$args);
....
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');

编辑 415 响应代码

这可能是双 urlencodeing 的问题。

尝试将参数设置为未编码的文本:

$args["documentType"] = "text/plain";
$args["documentContent"] = $text;
