使用 .访问 Google API OAuth2Service Account时出现问题google-api-php-client。我惊讶地发现这部分代码来自Google Dev 中设置的 JWT 声明示例，JWT Claim set当由于某种原因JWT Header通过 true 时返回错误，这让我感觉像 UTF-8 序列化并json_encode()在此处创建错误。

  $JWT_Header = array(
    "alg" => "RS256",
    "typ" => "JWT"
  );
  $JWT_Body = array(
    "iss" => "761326798069-r5mljlln1rd4lrbhg75efgigp36m78j5@developer.gserviceaccount.com",
    "scope" => "https://www.googleapis.com/auth/prediction",
    "aud" => "https://accounts.google.com/o/oauth2/token",
    "exp" => 1328554385,
    "iat" => 1328550785
  );

  $segments = array(
    rtrim(strtr(base64_encode(json_encode($JWT_Header)), '+/', '-_'), '='),
    rtrim(strtr(base64_encode(json_encode($JWT_Body)), '+/', '-_'), '=')
  );
  //echo '<pre>'; print_r($segments); echo '</pre>';

不同于Google Dev: Encoding the JWT Claim Set example of output中描述的内容

/*
    Output: 

    JWT header:
    Google Dev    eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.
     My output    eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.

    JWT Claim set:

有什么建议么？

它似乎与 UTF-8 没有任何关系。要调试，只需向后应用相同的算法：

$output = array(
    'eyJpc3MiOiI3NjEzMjY3OTgwNjktcjVtbGpsbG4xcmQ0bHJiaGc3NWVmZ2lncDM2bTc4ajVAZGV2ZWxvcGVyLmdzZXJ2aWNlYWNjb3VudC5jb20iLCJzY29wZSI6Imh0dHBzOi8vd3d3Lmdvb2dsZWFwaXMuY29tL2F1dGgvcHJlZGljdGlvbiIsImF1ZCI6Imh0dHBzOi8vYWNjb3VudHMuZ29vZ2xlLmNvbS9vL29hdXRoMi90b2tlbiIsImV4cCI6MTMyODU1NDM4NSwiaWF0IjoxMzI4NTUwNzg1fQ',
    'eyJpc3MiOiI3NjEzMjY3OTgwNjktcjVtbGpsbG4xcmQ0bHJiaGc3NWVmZ2lncDM2bTc4ajVAZGV2ZWxvcGVyLmdzZXJ2aWNlYWNjb3VudC5jb20iLCJzY29wZSI6Imh0dHBzOlwvXC93d3cuZ29vZ2xlYXBpcy5jb21cL2F1dGhcL3ByZWRpY3Rpb24iLCJhdWQiOiJodHRwczpcL1wvYWNjb3VudHMuZ29vZ2xlLmNvbVwvb1wvb2F1dGgyXC90b2tlbiIsImV4cCI6MTMyODU1NDM4NSwiaWF0IjoxMzI4NTUwNzg1fQ',
);

foreach($output as $i){
    print_r(base64_decode(strtr($i, '-_', '+/'))) . PHP_EOL;
    print_r(json_decode(base64_decode(strtr($i, '-_', '+/')))) . PHP_EOL;
}

您会看到 Google JSON 字符串包含相同的值，只是它们没有转义正斜杠：
