Groovy httpbuilder ResponseParseException 无效 JSON 字符串
Groovy httpbuilder ResponseParseException Invalid JSON string
我正在尝试使用 httpBuilder 在 groovy 中构建一个 api 消费者。我的后端 api returns json 输出内容类型 application/json。但是当我将 httpbuilder 对象中的内容类型设置为 JSON 时，它会抛出 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
的浏览器实际输出
{ "status" : "OK", "data" : { "totalTasks" : 0 }, "error" : "" }

当我访问的服务在 PHP 中时，问题就来了。
在 PHP 服务中，我使用 header('Content-Type: application/json'); 设置内容类型 application/json。然后在控制器中回显结果。
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。
