When I am doing request using different browser it is giving me proper xml response.

http://suggestqueries.google.com/complete/search?output=toolbar&hl=en&q=test&gl=US

Now I am request above url using curl command but it is giving me 400 error:

curl http://suggestqueries.google.com/complete/search?output=toolbar&hl=en&q=test&gl=US

Also I have passed user-agent but it is also giving me same error.

curl -A "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:27.0) Gecko/20100101 Firefox/27.0"  http://suggestqueries.google.com/complete/search?output=toolbar&hl=en&q=test&gl=US

Please guide If I missing somethings.

ERROR

400. That’s an error.

Your client has issued a malformed or illegal request. That’s all we know.

When I am trying below command:

curl -v -A "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:27.0) Gecko/20100101 Firefox/27.0" -H "Accept: application/xml" -H "Content-Type: application/xml" https://suggestqueries.google.com/complete/search?hl=en&q=test&gl=US&format=rich

Then getting response:

获取wireshark并检查包裹。它可能没用，因为我可以看到 curl 使用 SSL。但是，您可以检查您的浏览器是否也使用 SSL。如果没有，您将获得完整的软件包，您可以将其与 curl 输出进行比较并找出哪个字段导致错误（也检查来自谷歌的响应，它们可能不仅会因 400 响应而有所不同）。

您必须将网址放在引号中，请尝试：

curl 'http://suggestqueries.google.com/complete/search?output=toolbar&hl=en&q=test&gl=US'

&在大多数 shell 中都经过特殊处理。

正如您在发布的错误中看到的那样，网址在第一个&之前被剪切：

Done curl -v -A "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:27.0) 
Gecko/20100101 Firefox/27.0" -H "Accept: application/xml" -H "Content-Type: 
application/xml" https://suggestqueries.google.com/complete/search?hl=en

                                                                       |
