代碼中很多是業(yè)務(wù)谷扣,所以大家主要是參照setUp方法和get,post是怎么設(shè)置的谱仪。
另:
下載的jar包是2.1.6的。但用在項目中遇到
問題一:有亂碼否彩。解決方案:項目里的 Charsets.US_ASCII 都改成了 Charsets.UTF_8
問題二: 從客戶端獲取數(shù)據(jù)不完整疯攒。發(fā)現(xiàn)是LineEmitter 類的onDataAvailable(DataEmitter emitter, ByteBufferList bb)內(nèi)的代碼走不通。就把原來的:
@Override public void onDataAvailable(DataEmitter emitter, ByteBufferList bb) { while (bb.remaining() > 0) { byte b = bb.get(); if (b == '\n') { assert mLineCallback != null; mLineCallback.onStringAvailable(data.toString()); data = new StringBuilder(); return; } else { data.append((char)b); } } }
改成了:
@Override public void onDataAvailable(DataEmitter emitter, ByteBufferList bb) { String s = bb.readString(); if (s.indexOf("\n") > 0) mLineCallback.onStringAvailable(s); }}
就OK了
由于我用的是jar包的引用方式列荔,所以是依照上面改動原項目后導(dǎo)出了jar包卸例,導(dǎo)jar包方法:http://blog.csdn.net/u012319317/article/details/48133463
