ColdFusion和Twitter的JSON

Question

我運行下面的代碼我發現在互聯網上搶推文的負載與特定主題標籤：

<cfset consumerKey = "MY_CONSUMER_KEY"> 
<cfset consumerSecret = "MY_CONSUMER_SECRET"> 
<cfset bearerToken = ToBase64(consumerKey & ":" & consumerSecret)> 
<cfset authorization = "Basic " & bearerToken> 

<cfhttp url="https://api.twitter.com/oauth2/token" method="post" charset="utf-8"> 
    <cfhttpparam type="header" name="Authorization" value="#authorization#"> 
    <cfhttpparam type="header" name="Content-Type" value="application/x-www-form-urlencoded;charset=UTF-8"> 
    <cfhttpparam type="body" value="grant_type=client_credentials"> 
</cfhttp> 

<cfset bearerTokenResponse = DeserializeJSON(cfhttp.fileContent)> 
<cfset authorization2 = "Bearer " & bearerTokenResponse.access_token> 

<cfhttp url="https://api.twitter.com/1.1/search/tweets.json" method="get" charset="utf-8"> 
    <cfhttpparam type="header" name="Authorization" value="#authorization2#"> 
    <cfhttpparam type="url" name="q" value="%23ColdFusion"> 
</cfhttp> 

很顯然，我已經把我自己的鍵在consumerkey & consumersecret變量。

我已經搜索了好幾個星期的方式，我可以用它來以可讀的方式顯示。例如，假設我想在頁面上輸出實際的推文，誰發佈了推文和日期的句柄 - 怎麼樣！這讓我很生氣，因爲我確信我之前做過類似的事情，但不記得如何！

非常感謝提前。

Answer 1

我已經處理了一些模糊的類似之前。我得到的答案是將該JSON放入一個數組中並循環。

首先，我們需要我們的JSON與我們合作。我使用this online validator and formatter。使事情變得非常容易閱讀。

我擺脫了最後的因素，search_metadata，因爲它是所有我整潔的變量的另一個主要範圍，我們不能這樣做。要使用ColdFusion自動刪除它，您可能需要使用SpanExcluding函數。

所以，你留下了這一點：

[{"created_at":"Tue May 17 16:32:17 +0000 2016","id":732609696109080577,"id_str":"732609696109080577","text":"Well done Team Konstruct! \n\n#konstruct\n#pvd\n#suncity\n#dunhill https:\/\/t.co\/yRUPIXmQ6t","truncated":false,"entities":{"hashtags":[{"text":"konstruct","indices":[28,38]},{"text":"pvd","indices":[39,43]},{"text":"suncity","indices":[44,52]},{"text":"dunhill","indices":[53,61]}],"symbols":[],"user_mentions":[],"urls":[{"url":"https:\/\/t.co\/yRUPIXmQ6t","expanded_url":"http:\/\/fb.me\/3kyQTnmLe","display_url":"fb.me\/3kyQTnmLe","indices":[62,85]}]},"metadata":{"iso_language_code":"en","result_type":"recent"},"source":"\u003ca href=\"http:\/\/www.facebook.com\/twitter\" rel=\"nofollow\"\u003eFacebook\u003c\/a\u003e","in_reply_to_status_id":null,"in_reply_to_status_id_str":null,"in_reply_to_user_id":null,"in_reply_to_user_id_str":null,"in_reply_to_screen_name":null,"user":{"id":238145671,"id_str":"238145671","name":"Vincent Viljoen","screen_name":"konstructdesign","location":"Brackenfell, Cape Town","description":"I design and build exhibition stands. I love it when my clients win awards for their stands and their brands stand out because of my creativity...","url":"http:\/\/t.co\/soGTwPlFhi","entities":{"url":{"urls":[{"url":"http:\/\/t.co\/soGTwPlFhi","expanded_url":"http:\/\/konstruct.co.za","display_url":"konstruct.co.za","indices":[0,22]}]},"description":{"urls":[]}},"protected":false,"followers_count":589,"friends_count":1973,"listed_count":18,"created_at":"Fri Jan 14 13:36:08 +0000 2011","favourites_count":0,"utc_offset":7200,"time_zone":"Pretoria","geo_enabled":true,"verified":false,"statuses_count":1863,"lang":"en","contributors_enabled":false,"is_translator":false,"is_translation_enabled":false,"profile_background_color":"131516","profile_background_image_url":"http:\/\/abs.twimg.com\/images\/themes\/theme14\/bg.gif","profile_background_image_url_https":"https:\/\/abs.twimg.com\/images\/themes\/theme14\/bg.gif","profile_background_tile":false,"profile_image_url":"http:\/\/pbs.twimg.com\/profile_images\/1465748472\/VW_1_normal.jpg","profile_image_url_https":"https:\/\/pbs.twimg.com\/profile_images\/1465748472\/VW_1_normal.jpg","profile_banner_url":"https:\/\/pbs.twimg.com\/profile_banners\/238145671\/1369226061","profile_link_color":"009999","profile_sidebar_border_color":"FFFFFF","profile_sidebar_fill_color":"EFEFEF","profile_text_color":"333333","profile_use_background_image":true,"has_extended_profile":false,"default_profile":false,"default_profile_image":false,"following":null,"follow_request_sent":null,"notifications":null},"geo":null,"coordinates":null,"place":null,"contributors":null,"is_quote_status":false,"retweet_count":0,"favorite_count":0,"favorited":false,"retweeted":false,"possibly_sensitive":false,"lang":"en"}] 

我不知道你怎麼想親自來處理這個字符串，但我用了cfsavecontent把它變成一個名爲Tweets變量。

然後：

<cfset ArrayOfStructs = deserializeJson(Tweets)> 

現在，它的列表中，我可以通過它的循環，並抓住所有我想要的信息。例如：

<cfoutput> 
<cfloop array="#ArrayOfStructs#" index="i"> 
#i.created_at# <br/> 
#i.id_str# 
#i.text# <br/> 
#i.user.name# <br/> 
#i.user.screen_name# <br/> 
#i.user.url# <br/> 
</cfloop> 
</cfoutput> 

你可以抓住直來自Twitter的鳴叫嵌入代碼，然後填寫用戶名和身份號碼，網頁上的，這正是我所做的所有的好東西！

這應該適用於1推或1萬元。

這是否適合您？我正在使用ColdFusion 11.

編輯：只要您期待每次都使用完全相同的格式，則可以使用字符串函數解析出search_metadata元素。我不完全相信你會如何去了解它，但我剛纔扔了一起：

<!---Replace the beginning of the search_metadata element with a unique character---> 
<cfset Tweets2 = replace(Tweets,',"search_metadata',"|")> 

<!---Use SpanExcluding function to eliminate everything past the unique character.---> 
<cfset Tweets3 = SpanExcluding(Tweets2, '|')> 

你最好還是手動添加}到了最後，但是這是學術。你用同樣的字符串結束了我應該能夠循環。

Answer 2

回答你的意見，你可以使用for循環遍歷CFSCRIPT中的數組。

// from/to loop 
for (i=1;i LTE ArrayLen(array);i=i+1) { 
    WriteOutput(array[i]); 
} 

OR

// for .. in loop 
for (elem in array) { 
    WriteOutput(elem); 
} 

你的情況，那就是：

response = DeserializeJSON(cfhttp.fileContent); 
for (status in response.statuses) { 
    WriteOutput(status.id); 
} 

我當然會通過函數（S）更換新的運行結構的文本部分帶有中斷標籤的行，並使網址固定標籤。
