android - 从 IIS 7.5 下载 APK 下载失败

Question

从 apache 服务器下载时此代码可以正常工作，没有问题。但是当使用iis 7.5进行测试时，当前安装在win7上。它似乎不适用于 getInputStream();尽管在调试并将其粘贴到浏览器中时会显示文件的完整地址，但会开始下载 apk

阅读本网站和互联网已添加 MIME TYPE .apk application/vnd.android.package-archive

try {

                        URL url = new URL(prefs.getString("server_address", null) + "/updates/filename.apk");
                        HttpURLConnection c = (HttpURLConnection) url.openConnection();
                        c.setRequestMethod("GET");
                        c.setDoOutput(true);
                        c.connect();

Answer 1

只需删除此代码即可:

      c.setRequestMethod("GET");
      c.setDoOutput(true);
      c.connect();

第一个不是必需的，第二个，c.setDoOutput(true);正在将请求方法更改为POST ... 这就是为什么你会收到 405 method not allowed ...
