我正在尝试创建一个简单的HTTP POST请求,我不知道为什么以下失败.我试着按照这里的例子,我不知道我哪里出错了.
例外
java.lang.NullPointerException
at groovyx.net.http.HTTPBuilder$RequestConfigDelegate.setBody(HTTPBuilder.java:1131)
...
码
def List<String> search(String query, int maxResults)
{
def http = new HTTPBuilder("mywebsite")
http.request(POST) {
uri.path = '/search/'
body = [string1: "", query: "test"]
requestContentType = URLENC
headers.'User-Agent' = 'Mozilla/5.0 Ubuntu/8.10 Firefox/3.0.4'
response.success = { resp, InputStreamReader reader ->
assert resp.statusLine.statusCode == 200
String data = reader.readLines().join()
println data
}
}
[]
}
我试图理解HTTP Builder的简化GET.我成功地使用类似于REST GET请求的简单GET请求.
def client = new HTTPBuilder('http://pokeapi.co')
def resp = client.get(path: '/api/v1/pokemon/1')
static void main(String[] args){
def h = new HTTP()
print h.resp.name
}
我接下来要做的是为查询添加参数.
def client = new HTTPBuilder('http://svcs.sandbox.ebay.com')
def resp = client.get(path: '/services/search/FindingService/v1',
contentType: TEXT,
query:[
'SECURITY-APPNAME': APP_ID,
'OPERATION-NAME':'findItemsByKeywords',
'SERVICE_VERSION':'1.0.0',
'RESPONSE-DATA-FORMAT':'JSON',
'callback':'_cb_findItemsByKeywords',
'REST-PAYLOAD': '',
'keywords':'iphone 3g',
'paginationInput.entriesPerPage': '3'])
}
当我打印时resp,我得到:
java.io.StringReader@16d871c0
参数的代码是否正确？我的输出有什么问题？
我的查询(当我通过浏览器运行时)产生
{"findItemsByKeywordsResponse":[{"ack":["Success"],"version":["1.13.0"],"timestamp":["2014-12-02T06:26:15.869Z"],"searchResult":[{"@count":"3","item":[{"itemId":["110089183401"],"title":["Apple iPhone 3G - 8GB - Black (Unlocked) Smartphone"],"globalId":["EBAY-US"],"primaryCategory":[{"categoryId":["9355"],"categoryName":["Cell Phones & Smartphones"]}],"galleryURL":["http:\/\/thumbs2.sandbox.ebaystatic.com\/m\/mI_iSJ1zmYlidmuoLh9Pndw\/140.jpg"],"viewItemURL":["http:\/\/cgi.sandbox.ebay.com\/Apple-iPhone-3G-8GB-Black-Unlocked-Smartphone-\/110089183401"],"productId":[{"@type":"ReferenceID","__value__":"100014203"}],"paymentMethod":["PayPal"],"autoPay":["false"],"postalCode":["95125"],"location":["San Jose,CA,USA"],"country":["US"],"shippingInfo":[{"shippingServiceCost":[{"@currencyId":"USD","__value__":"2.5"}],"shippingType":["Flat"],"shipToLocations":["US"],"expeditedShipping":["false"],"oneDayShippingAvailable":["false"],"handlingTime":["3"]}],"sellingStatus":[{"currentPrice":[{"@currencyId":"USD","__value__":"100.0"}],"convertedCurrentPrice":[{"@currencyId":"USD","__value__":"100.0"}],"sellingState":["Active"],"timeLeft":["P25DT9H19M59S"]}],"listingInfo":[{"bestOfferEnabled":["false"],"buyItNowAvailable":["false"],"startTime":["2011-05-17T15:41:14.000Z"],"endTime":["2014-12-27T15:46:14.000Z"],"listingType":["FixedPrice"],"gift":["false"]}],"returnsAccepted":["true"],"condition":[{"conditionId":["1000"],"conditionDisplayName":["New"]}],"isMultiVariationListing":["false"],"topRatedListing":["false"]},{"itemId":["110116107959"],"title":["Apple iPhone 3G - 8GB - Black (AT&T) Smartphone (MB046LL\/A)"],"globalId":["EBAY-US"],"primaryCategory":[{"categoryId":["9355"],"categoryName":["Cell …我需要向Web服务器发送POST请求,并能够读取所述服务器发送的响应.我试着用这个代码使用HTTPBuilder lib:
def http = new HTTPBuilder('http://myServer/')
http.setProxy("Proxy_IP", 8080, "http")
postBody = [cmd:'e',format:'sep',c:'a',b:'b',t:'u',r:'r',kl:'lop']
http.post( body: postBody,
requestContentType: URLENC ){ resp ->
HttpEntity he = resp.getEntity()
println "${resp.getAllHeaders()}"
println he.getContentType()
println "${resp.getEntity().getContent()}"
}
执行此代码时出现异常:
ERROR errors.GrailsExceptionResolver - EOFException occurred when processing request: [GET] /PROJECT/home/index
Unexpected end of ZLIB input stream. Stacktrace follows:
Message: Unexpected end of ZLIB input stream

我使用了groovy http builder
def http = new HTTPBuilder(url)
http.auth.basic('username', 'password')
try {
http.request(Method.POST, ContentType.TEXT) {
req->
headers.accept = "application/xml"
body = request //xml request
response.success = {
resp,reader ->
Response = reader.text
}
}
}
catch(HttpResponseException ex) {
println ex;
}
在这种情况下如何解决这个问题..？
Grails中的HTTPBuilder是否安全？
如果HTTPBuilder连接到Grails服务类,它是否可以安全使用？或者它应该在每次调用时实例化？
关于Grails中的HTTPBuilder是否是线程安全的,似乎没有任何具体的答案.由于缺乏关于特定方面的文档,我倾向于使用非线程安全,但我想要一个确定的答案.
代码似乎表明,处理来自多个线程的多个请求应该可以,只要它们将使用相同的上下文(头文件,身份验证器等)进入相同的URL.
最新版本的Grails REST客户端插件:
withHttp(uri: "http://foo/bar") {
def bodyContent = [
apiKey: "somekey",
identifier: identity.identity,
activity: ac as JSON
]
def json = post(path: 'activity', body: bodyContent)
if (json.stat == 'ok') {
wsr.success = true
}
}
如何向此请求添加标头数据？
尝试模拟需要将一些INPUT/TEXT字段与文件中的数据组合在一起的HTTP POST.看起来我可以有一个或另一个,但不是两个？
在下面的代码段中,paramsToPost = [name:'John',年龄:22]
@Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.5.0')
Boolean doHttpPost(String url, Map paramsToPost, String fileContent) {
HTTPBuilder http = new HTTPBuilder(url)
def resp = http.request(Method.POST ) { req ->
MultipartEntity mpe = new MultipartEntity()
mpe.addPart "foo", new StringBody(fileContent)
req.entity = mpe
// body = paramsToPost // no such property
}
println "response: ${resp}"
return true
}
有人有工作样品吗？
使用cURL我可以发送一个正文的GET请求.例:
curl -i -X GET http://localhost:8081/myproject/someController/l2json -H "content-type: application/json" -d "{\"stuff\":\"yes\",\"listThing\":[1,2,3],\"listObjects\":[{\"one\":\"thing\"},{\"two\":\"thing2\"}]}"
为了清晰起见,这是合理格式的JSON:
{"stuff":"yes",
"listThing":[1,2,3],
"listObjects":[{"one":"thing"},{"two":"thing2"}]}
通常-d会告诉cURL发送一个POST,但我已经确认它-X GET正在覆盖它并且它正在发送GET.是否可以使用HTTPBuilder复制它？
我已经做好了:
def http = new HTTPBuilder( 'http://localhost:8081/' )
http.post(path:'/myproject/myController/l2json', body:jsonMe, requestContentType:ContentType.JSON) { resp ->
println "Tweet response status: ${resp.statusLine}"
assert resp.statusLine.statusCode == 200
}
哪个有效,但如果我.post改为.get我得到错误:
Cannot set a request body for a GET method. Stacktrace follows:
Message: Cannot set a request body for a GET method

->> 1144 | setBody in groovyx.net.http.HTTPBuilder$RequestConfigDelegate …请注意:使用下面的代码/信息,这个问题可以在2-3分钟内重现.
背景:首先我还没有找到一个插件来帮助支持Paypal高级界面(他们在"标准"和"专业版"之间的中级解决方案),但是如果我不需要滚动我自己的HTTPBuilder和其他界面代码我绝对是为了那个.
现在,我能够缩小HTTPBuilder问题,使用正确的URL从DW提示符开始使用curl命令; 我无法让它与groovy的HTTPBuilder一起工作.
那么,一个人可以轻松尝试的是:
c:\groovy\ex>curl https://pilot-payflowpro.paypal.com
curl: (52) Empty reply from server
但还是回复.或者从Paypal获得SECURETOKEN的真实URL更像是:
c:\groovy\ex>curl https://pilot-payflowpro.paypal.com -kd "PARTNER=PayPal&VENDOR=ROAdvanced&USER=ROAdvanced&PWD=joespizza1&TRXTYPE=S&MODE=TEST&AMT=40&CREATESECURETOKEN=Y&SECURETOKENID=12528208de1413abc3d60c86233"
RESULT=0&SECURETOKEN=15XTWEZtFlkeNqtWCBZHSTgcs&SECURETOKENID=12528208de1413abc3d60c86233&RESPMSG=Approved
OR you'll get a result like the following, but either result is good, since Paypal is sending a response in both cases!
RESULT=7&SECURETOKENID=12528208de1413abc3d60c86233&RESPMSG=Field format error: Secure Token Id already been used
好的,我的代码如下.即使(我认为)我正在使用延迟,请注意我的代码错误立即失败:
Class: org.apache.http.NoHttpResponseException
Message: The target server failed to respond
这发生在
http.request(GET, ContentType.ANY) {
请注意,即使设置HTTPBuilder的延迟,此故障也会立即发生.我会把整个代码/堆栈跟踪放在最后.另请注意,如果按照本文所述添加SSL安全性,则结果是相同的错误,即服务器无法响应.
所以代码是:
package apps
import grails.converters.*
import org.codehaus.groovy.grails.web.json.*; // package containing JSONObject, JSONArray,...
import …我正在获取groovyx.net.http.HttpResponseException: Not Found并希望查看来自的日志HTTPBuilder。我正在将Groovy 2.1.9与一起使用groovyConsole。
因此，我检查了该博客文章，其中提到有关添加log4j.xml到的信息groovy.home/conf/。我做到了，这是我的文件：
