php - Groovy httpbuilder ResponseParseException无效的JSON字符串

Question

我试图使用httpBuilder在groovy中构建一个api使用者。我的后端api返回内容类型为application / json的json输出。但是，当我将httpbuilder对象中的内容类型设置为JSON时，会引发Invalid Json String错误。

static def webServiceRequest(String baseUrl, String path, def data,method=Method.GET,contentType=ContentType.JSON){
        try {
            def ret = null
            def http = new HTTPBuilder(baseUrl)
            http.request(method, contentType) {
                uri.path = path
                if(method==Method.GET)
                    uri.query = data
                else
                    body = data
                headers.'User-Agent' = 'Mozilla/5.0 Ubuntu/8.10 Firefox/3.0.4'


                response.success = { resp, json ->
                    println "response status: ${resp.statusLine}"
                    ret = json
                    println '--------------------'
                }
            }
            return ret

        } catch (Exception ex) {
            ex.printStackTrace();
            return null;
        }
    }

上面的函数调用了api。

def response = webServiceRequest(grailsApplication.config.getProperty ("site.triggerReasons"),'/do/dataquality/FOSAutomation/doAction/',data,Method.GET,ContentType.JSON)

内容类型为application / json的浏览器上的实际输出

{ "status" : "OK", "data" : { "totalTasks" : 0 }, "error" : "" }

异常stacktrace:

当我要使用的服务是PHP时，问题就来了。
在PHP服务中，我使用 header 设置内容类型application / json('Content-Type:application / json'); 。然后在 Controller 中回显结果。

Answer 1

问题出在groovy-httpbuilder jar的版本中。我使用的是旧版本(0.5.0-RC2)。

compile group: 'org.codehaus.groovy.modules.http-builder', name: 'http-builder', version: '0.5.0-RC2'

现在我将其更改为最新的0.7.1

compile group: 'org.codehaus.groovy.modules.http-builder', name: 'http-builder', version: '0.7.1'

现在工作正常。
