curlからのJSON応答をプリティファイしようとしていますが、機能しません。

「JSONオブジェクトをデコードできませんでした」と表示されるのはなぜですか？私が要求しているURLは常に有効なjsonを返します。$ echojsonreponse|のように手動で応答からjsonを渡す場合 python -m json.tool、jsonをきれいにします。

私は何か間違ったことをしていますか？

URLを引用符で囲む必要があります。

curl -s "https://api.vk.com/method/photos.getAlbums?uid=6015870&access_token=0275127e915981fe795840165e532169482cbdfc4ca1dbd48619a687a65fead88c468cdafe9743e231c37" | python -m json.tool

&文字はシェルメタ文字であり、コマンドをバックグラウンドで実行します。その結果、完全なURLをサーバーに渡すのではなく、curl -s https://api.vk.com/method/photos.getAlbums?uid=6015870代わりにコマンドをバックグラウンドで実行します。

これが、シェルがエコー[4] 8822する理由です。これまでに4番目のジョブをジョブキューに入れると、PID8822が与えられました。

残りのコマンドは次のとおりです。

access_token=0275127e915981fe795840165e532169482cbdfc4ca1dbd48619a687a65fead88c468cdafe9743e231c37 | python -m json.tool

これは実際には有効なJSONを生成しません：

$ access_token=0275127e915981fe795840165e532169482cbdfc4ca1dbd48619a687a65fead88c468cdafe9743e231c37 | python -m json.tool
No JSON object could be decoded

次の行で、バックグラウンドに配置したジョブが完了したことを確認できます。

私のIPアドレスに適切なアクセストークンがないことは明らかなので、おそらくあなたにとってはより有用な情報が得られるでしょう。:-)

あなたのURLを引用してください。これは壊れています：

curl https://api.github.com/repos/mojombo/jekyll/issues?state=closed&assignee=mojombo | python -mjson.tool

これは正しいです：

curl 'https://api.github.com/repos/mojombo/jekyll/issues?state=closed&assignee=mojombo' | python -mjson.tool
