Groovy HTTPBuilder在解析有效的json時產生錯誤

我是一名Groovy新手，並嘗試從Groovy腳本連接到GitHub API，但是當HTTPBuilder嘗試解析JSON響應時出現奇怪的錯誤。Groovy HTTPBuilder在解析有效的json時產生錯誤

我的簡單腳本如下

@Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.7.2') 
import groovyx.net.http.* 
import static groovyx.net.http.ContentType.* 
import static groovyx.net.http.Method.* 

def apiToken = '[api_token]' 

def http = new HTTPBuilder('https://api.github.com/') 

// perform a GET request, expecting JSON response data 
http.request(GET, JSON) { 

    uri.path = '/orgs/octokit/repos' 
    headers.'Accept' = 'application/json' 
    headers.'Authorization' = 'Basic ' + (apiToken + ':').bytes.encodeBase64().toString() 
    headers.'User-Agent' = '[username]' 

    // response handler for a success response code: 
    response.success = { resp, json -> 
    println resp.statusLine 
    } 

    // handler for any failure status code: 
    response.failure = { resp -> 
    println "Unexpected error: ${resp.statusLine.statusCode} : ${resp.statusLine.reasonPhrase}" 
    } 
}

但當JSON解析我收到以下錯誤

錯誤似乎暗示無效JSON但我已確認的響應的確正如您對Github API期望的那樣有效。

更奇怪的是，如果我完全刪除了「授權」報頭和發送請求未經身份驗證，它工作正常：S

保存響應JSON和嘗試解析它Groovy的JSON解析器 – injecteer 2014-09-06 21:47:59

請你提供JSON響應你越來越了？ – Opal 2014-09-07 12:32:07

提供的代碼對我來說工作正常。 – Opal 2014-09-07 12:36:58

它使用Groovy的最新版本的問題。我遇到過同樣的問題。你的代碼應該可以在2.3.0之前使用Groovy的版本。或者，您可以爲HTTPBuilder嘗試不同的默認JSONParserType。

見 http://beta.groovy-lang.org/docs/groovy-2.3.0/html/gapi/groovy/json/JsonSlurper.html http://alfonsorv.com/instruct-groovy-httpbuilder-to-handle-a-json-response-with-wrong-content-type/

專注，切換到2.2.2及其工作。 – 3urdoch 2014-09-11 21:08:50

這裏是我的代碼工作周圍

/* 
    * Normally we would use the method "request(GET, JSON)" to return a json result, but with the release 
    * of groovy 2.3.0, which included extensive changes to JSON parsing, the result returned from the 
    * Artifactory REST API call 'File List' could not be parsed by HTTPBuilder's default JSON parser. 
    * 
    * Specifying the content type as TEXT removes the parsing from the call. Code was added to parse the returned 
    * text into JSON using the more lenient 'LAX' parser. 
    */ 
    http.request(GET, TEXT) { 
     //Since content type is text, we need to specify that a json response is acceptable. 
     headers.Accept = 'application/json' 
     headers.'User-Agent' = USER_AGENT 

     response.success = { respnse, reader -> 

      def jsonText = reader.text 
      def parser = new JsonSlurper().setType(JsonParserType.LAX) 
      def jsonResp = parser.parseText(jsonText) 
      //Add up the size of all the files in this directory 
      // 
      jsonResp.files.each { 
       directorySize = directorySize + Integer.parseInt("${it.size}".toString()) 
      } 
     } 
    }

你應該更新你的現有答案，而不是創建第二個答案。 – 3urdoch 2014-09-14 15:54:12

@murdoch我正面臨同樣的問題，但不幸的是改變Groovy版本目前不是一種選擇。任何關於如何將您的解決方法適用於將JSON發佈到遠程服務的方案的想法，或者我註定只要'Content-Type = applicaton/json？' – Sitati 2015-06-17 08:58:20

我實際上發現此解決方法 - https：/ /gist.github.com/zedar/abbb3c01635c0d6a977f 僅在JsonSlurper之前調用只讀取讀取器的響應處理程序閉包。 – Sitati 2015-06-17 10:34:33

請不要發佈代碼的答案。解釋代碼是如何工作的。 – 2016-04-18 03:37:11
