groovy / grails – 无法使HTTPBuilder使用URL(由Paypal提供)

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:groovyex>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:groovyex>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,如果添加SSL安全性as described in this post,结果是相同的错误,即服务器无法响应.

所以代码是：

…

dependencies {
    // specify dependencies here under either 'build','compile','runtime','test' or 'provided' scopes e.g.
    compile('org.codehaus.groovy.modules.http-builder:http-builder:0.5.2') {

    }

—————————-每个Ralf的响应代码更新————-

代码希望匹配Groovy HTTPBuilder documentation：

注意这会产生相同的错误,同一行,I.E.：

在该行：http.request(POST){
