如何使用 HttpComponents 发布数组参数

问题描述

我想用 Apache http-components (4.1.2) 执行这个命令

 curl --data "strings[]=testOne&string-keys[]=test.one&strings[]=testTwo&string-keys[]=test.two&project=Test" https:///api.foo.com/1/string/input-bulk

目标api需要strings和string-keys参数作为array，这意味着重复strings[]和 string-keys[] 用于每个参数.

这个 curl 命令工作正常，但使用 Http 组件，而我得到的参数完全相同.

也许我做错了什么.

 Listparams = new ArrayList();params.add( new BasicNameValuePair( "project", PROJECT_NAME));对于(条目条目:newEntries){params.add( new BasicNameValuePair( "string-keys[]", entry.getKey()));params.add( new BasicNameValuePair( "strings[]", entry.getValue()));params.add( new BasicNameValuePair( "context[]", "" ));}URI uri = URIUtils.createURI( "https", "api.foo.com", -1, "/1/string/input-bulk", null, null );UrlEncodedFormEntity paramEntity = new UrlEncodedFormEntity( params);logger.info("POST 参数:{}"，EntityUtils.toString(paramEntity));HttpPost httpRequest = new HttpPost( uri );httpRequest.setEntity( paramEntity );HttpResponse 响应 = 新的 DefaultHttpClient().execute(httpRequest);

POST 参数如下所示:

POST 参数:project=Test&string-keys%5B%5D=test.one&strings%5B%5D=TestOne&string-keys%5B%5D=test.two&strings%5B%5D=测试二

如果我将它们放在 curl 中的 --data 后面，它可以工作，但不适用于 HttpCoponents.有人能解释一下为什么吗?

提前致谢

解决方案

尝试在您的 httpRequest 添加标题application/x-www-form-urlencoded"

httpRequest.addHeader("content-type", "application/x-www-form-urlencoded");HttpResponse 响应 = 新的 DefaultHttpClient().execute(httpRequest);

希望能奏效

I want to perform this command with Apache http-components (4.1.2)

 curl  --data "strings[]=testOne&string-keys[]=test.one&strings[]=testTwo&string-keys[]=test.two&project=Test" https://api.foo.com/1/string/input-bulk

The target api need strings and string-keys parameters as array, which mean repeating strings[] and string-keys[] for each parameter.

This curl command works fine but with Http-component, while I got exactly the same parameters.

Maybe I'm doing something wrong.

    List<NameValuePair> params = new ArrayList<NameValuePair>();
    params.add( new BasicNameValuePair( "project", PROJECT_NAME ) );

    for ( Entry entry : newEntries )
    {
        params.add( new BasicNameValuePair( "string-keys[]", entry.getKey() ) );
        params.add( new BasicNameValuePair( "strings[]", entry.getValue() ) );
        params.add( new BasicNameValuePair( "context[]", "" ) );
    }

    URI uri = URIUtils.createURI( "https", "api.foo.com", -1, "/1/string/input-bulk", null, null );

    UrlEncodedFormEntity paramEntity = new UrlEncodedFormEntity( params );
    logger.info( "POST params : {}", EntityUtils.toString( paramEntity ) );
    HttpPost httpRequest = new HttpPost( uri );
    httpRequest.setEntity( paramEntity );

    HttpResponse response = new DefaultHttpClient().execute( httpRequest );

The POST params looks like :

POST params : project=Test&string-keys%5B%5D=test.one&strings%5B%5D=TestOne&string-keys%5B%5D=test.two&strings%5B%5D=TestTwo

If I put them behind --data in curl, it works, but not with HttpCoponents.Can someone explain me why?

Thanks in advance

解决方案

Try adding the header "application/x-www-form-urlencoded" in your httpRequest

    httpRequest.addHeader("content-type", "application/x-www-form-urlencoded");
    HttpResponse response = new DefaultHttpClient().execute( httpRequest );

Hopefully that will work
