Question

以下代码在我的PC上运行正常，服务器返回200 Ok以及正确的输出。当我在Android上试用它时，服务器会重新运行：

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<title>Error 405 Method Not Allowed</title>
</head>
<body><h2>HTTP ERROR 405</h2>
<p>Problem accessing /sg-1/locations/. Reason:
<pre>    Method Not Allowed</pre></p><hr><i><small>Powered by Jetty://</small></i><hr/></html>

代码：

HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection();
    connection.setDoOutput(true); // Triggers POST.
    // connection.setRequestProperty("Accept-Charset", charset);
    connection.setRequestProperty("Content-Type", "application/json");
    connection.setRequestProperty("X-Session", token);

    connection.connect();
    InputStream response;
    boolean worked = false;
    if (connection.getResponseCode() != HttpURLConnection.HTTP_OK)
        response = connection.getErrorStream();
    else {
        response = connection.getInputStream();
        worked = true;
    }
    java.util.Scanner s = new java.util.Scanner(response).useDelimiter("\\A");
    String result = s.hasNext() ? s.next() : "";
    System.out.println(result);

Answer 1

您的代码在Java SE中发送GET，在Android中发送POST。似乎服务器期待GET请求，因此请阻止在Android中发送POST：

// connection.setDoOutput(true);

HttpURLConnections适用于PC但不适用于Android
