android–ProtocolException：无效的标题::在HTTPRequest上

概述这真的很奇怪.我有一个看起来几乎相同但不抛出异常的函数.这是有问题的代码：publicHeader[]generateHeaders(){Header[]headers=newHeader[2];headers[0]=newBasicHeader("Client","android");headers[1]=newBasicHeader("Accept","applicat

这真的很奇怪.我有一个看起来几乎相同但不抛出异常的函数.这是有问题的代码：

public header[] generateheaders() {    header[] headers = new header[2];    headers[0] = new Basicheader("ClIEnt", "androID");    headers[1] = new Basicheader("Accept", "application/Json; charset=UTF-8");    return headers;}public httpPost gethttpRequestPost() throws URISyntaxException {    httpPost request = new httpPost(new URI(generatequeryUrl()));    request.setheaders(generateheaders());    setTimeout(request);    return request;}protected query buildquery() {    query query = null;    query = new query(new Config(), getContext());    query.addOrderedParam(FUNCTION_name);    return query;}

下面的代码会导致ClIEntProtocolException,正是这样：引起：org.apache.http.ProtocolException：无效的标题::

public httpResponse execute() throws URISyntaxException, ClIEntProtocolException,        IOException {    httpClIEnt clIEnt = new DefaulthttpClIEnt();    httpResponse response = response = clIEnt.execute(buildquery().gethttpRequestPost());    return response;}

它没有指向2个标题中的任何一个,但是像一些空标题.这里发生了什么？

在clIEnt.execute(…)内部发生异常,显然我无法在那里调试…

那些可能是响应标题…但是我在fiddler中看不到任何错误.这是请求和响应机构：

请求

GET http://myapp.API.pl/API/bankname?accountNumber=32195000012006548541990002 http/1.1User-Agent: fiddlerAccept: application/JsonClIEnt: androIDHost: myapp.API.pl

响应

http/1.1 404 Not FoundDate: Tue, 12 Nov 2013 08:35:01 GMTServer: ApacheX-Powered-By: PlesklinContent-Length: 0Connection: closeContent-Type: application/Json; charset=UTF-8

好吧我撒了一点,并不是所有东西都是小提琴手.如果参数accountNumber指定了错误的数字,则函数应返回404.确实如此,但fiddler中也有错误d出：

解决方法:

服务器似乎响应无效的http标头.

我想从’org.apache.http.message.Bufferedheader’中引发了异常：

    if (buffer == null) {        throw new IllegalArgumentException            ("Char array buffer may not be null");    }    int colon = buffer.indexOf(':');    if (colon == -1) {        throw new ParseException            ("InvalID header: " + buffer.toString());    }    String s = buffer.substringTrimmed(0, colon);    if (s.length() == 0) {        throw new ParseException            ("InvalID header: " + buffer.toString());    }    this.buffer = buffer;    this.name = s;    this.valuePos = colon + 1;

你可以通过tcp dump转储整个http体,还是通过curl枚举？
