Twitter search by hashtag example API v1.1
提问by John
In the past, using Twitter API version 1, I used the following URL to get a JSON feed of all tweets with the hashtag "baseball":
过去，使用 Twitter API 版本 1，我使用以下 URL 获取所有带有主题标签“棒球”的推文的 JSON 提要：
http://search.twitter.com/search.json?q=%23baseball&result_type=recent
http://search.twitter.com/search.json?q=%23baseball&result_type=recent
How do you achieve a similar result using API version 1.1? I'm using PHP as my server-side code, so not sure if I need to use it to authenticate and such?
您如何使用 API 1.1 版获得类似的结果？我使用 PHP 作为我的服务器端代码，所以不确定我是否需要使用它来进行身份验证等等？
Sample code would be extremely helpful. Thanks.
示例代码将非常有帮助。谢谢。

As you know, authenticated requests are now required, so there's a few things that you may need to take a look at first. The new 1.1 search, how to use hashtags, and authentication.
如您所知，现在需要经过身份验证的请求，因此您可能需要先了解一些事项。新的 1.1 搜索、如何使用主题标签和身份验证。
Twitter Search for 1.1
Twitter 搜索 1.1
The new twitter search api docs can be found here. According to these docs:
可以在此处找到新的 twitter 搜索 api 文档。根据这些文档：
https://api.twitter.com/1.1/search/tweets.jsonis the new resource URL to use for search.
https://api.twitter.com/1.1/search/tweets.json是用于搜索的新资源 URL。
Hashtag searches
标签搜索
You've got that part right! %23decodes to a #character.
你说对了那部分！%23解码为一个#字符。
Authentication
验证
OAuth is a lot more complex. It would help if you just used a library that just worked.
OAuth 要复杂得多。如果您只是使用一个刚刚工作的库，那会有所帮助。
Here's a posta lot of people found useful to help you make authenticated requests to the 1.1 API. This includes a one-file include libraryto make requests like those you require.
这是一篇很多人发现的帖子，可帮助您向 1.1 API 发出经过身份验证的请求。这包括一个单文件包含库，用于发出您需要的请求。
Example
例子
This example assumes you're using the above library and set up your keys etc. To make your request:
此示例假设您正在使用上述库并设置您的密钥等。要提出您的请求：
// Your specific requirements
$url = 'https://api.twitter.com/1.1/search/tweets.json';
$requestMethod = 'GET';
$getfield = '?q=#baseball&result_type=recent';
// Perform the request
$twitter = new TwitterAPIExchange($settings);
echo $twitter->setGetfield($getfield)
->buildOauth($url, $requestMethod)
->performRequest();
Yes, that's it. Apart from the little setting up you need to do (as my post explains), for your dev keys, that's everything you need to perform authenticated requests.
对，就是那样。除了您需要做的一些小设置（正如我的帖子所解释的），对于您的开发密钥，这就是您执行经过身份验证的请求所需的一切。
Response
回复
The response is returned to you in JSON. From the overview:
响应以 JSON 形式返回给您。从概述：
API v1.1 will support JSON only. We've been hinting at this for some time now, first dropping XML support on the Streaming API and more recently on the trends API. We've chosen to throw our support behind the JSON format shared across the platform.
API v1.1 将仅支持 JSON。一段时间以来，我们一直在暗示这一点，首先是在 Streaming API 和最近的趋势 API 上放弃 XML 支持。我们选择支持跨平台共享的 JSON 格式。

If you just want to test, you can do the follow:
如果您只是想测试，可以执行以下操作：
Access the twitter dev console: https://dev.twitter.com/console
访问 twitter 开发控制台：https: //dev.twitter.com/console
In Authentication put: OAuth 1, that will ask you to give permission from your twitter account.
在 Authentication put: OAuth 1 中，这将要求您从您的 twitter 帐户中授予权限。
Request URL put GET
请求 URL put GET
In url: https://api.twitter.com/1.1/search/tweets.json?q=%23yourhashtag
在网址中：https: //api.twitter.com/1.1/search/tweets.json?q =%23yourhashtag
After Send, in Request window, copy the Authorization value.
发送后，在请求窗口中，复制授权值。
Now put it in your request header.
现在把它放在你的请求头中。
Go example:
去例子：
func main() {
client := &http.Client{}
req, _ := http.NewRequest("GET", "https://api.twitter.com/1.1/search/tweets.json?q=%23golang", nil)
req.Header.Add("Authorization", `OAuth oauth_consumer_key=...`)
resp, _ := client.Do(req)
io.Copy(os.Stdout, resp.Body)
}

Here's a simple example in python using application-only auth using the requests API. Get keys by creating an app at https://apps.twitter.com/app/new.
这是使用请求 API 使用仅应用程序身份验证的 Python 中的简单示例。通过在https://apps.twitter.com/app/new创建应用程序来获取密钥。
api_key = ...
api_secret = ...
# https://dev.twitter.com/oauth/application-only
# The base64 stuff described there is the normal Basic Auth dance.
import requests
r = requests.post('https://api.twitter.com/oauth2/token',
auth=(api_key, api_secret),
headers={'Content-Type':
'application/x-www-form-urlencoded;charset=UTF-8'},
data='grant_type=client_credentials')
assert r.json()['token_type'] == 'bearer'
bearer = r.json()['access_token']
url = 'https://api.twitter.com/1.1/search/tweets.json?q=%23yourhashtag'
r = requests.get(url, headers={'Authorization': 'Bearer ' + bearer})
print r.json()
