Question

这是我的unsplash API的HTTP请求代码在浏览器中打开时HTTP运行成功，但在java中的HTTP请求中，我有这个问题

我如何解决这个问题

注意：此代码使用Instagram API成功运行

        new Thread() {
            @Override
            public void run() {

                Log.i("ttttttrrrraaaaiiiinnn", "Getting access token");
                try {
                    URL url = new URL("https://api.unsplash.com/photos?client_id=***");
                    Log.i("", "Send GET url liked image" + url.toString());
                    HttpURLConnection urlConnection = (HttpURLConnection) url
                            .openConnection();
                    urlConnection.setRequestMethod("POST");
                    urlConnection.setDoInput(true);
                    OutputStreamWriter writer = new OutputStreamWriter(
                            urlConnection.getOutputStream());
                    writer.write("url");
                    writer.flush();
                    String response = Utils.streamToString(urlConnection
                            .getInputStream());
                    Log.i("", "*?*?*?*?*?*?*?*?*?*?*? response *?*?*?*?*?*?*?*?*?*?*?" + response);
                    JSONObject jsonObj = (JSONObject) new JSONTokener(response)
                            .nextValue();

                    tv.setText(jsonObj.toString());



                } catch (Exception ex) {
                    ex.printStackTrace();
                }

            }
        }.start();

错误

java.io.FileNotFoundException: https://api.unsplash.com/photos?client_id=****
W/System.err:     at com.android.okhttp.internal.huc.HttpURLConnectionImpl.getInputStream(HttpURLConnectionImpl.java:260)

restful api只支持GET访问，你应该改变请求的方法/删除setRequestMethod（...）的行。你不能写一些东西到服务器，所以你必须删除out变量和相对语句行。

urlConnection.setRequestMethod("GET");//by default is GET

用于unsplash API的java.io.FileNotFoundException
