需要修改的報(bào)文

這一看就知道上邊的報(bào)文在postman里邊肯定會(huì)報(bào)錯(cuò)，因?yàn)閑xp_Content，因此他又沒有用到，所以你想把他刪掉。其實(shí)也沒那么難刪
也就是用到了流轉(zhuǎn)字符串。字符串固定字符查找，然后進(jìn)行字符串轉(zhuǎn)字符流，刪掉字符流中固定字符，之后再轉(zhuǎn)回來。因?yàn)樽址呀?jīng)是final了所以很多用法都是使用字符串轉(zhuǎn)字符流實(shí)現(xiàn)的
實(shí)現(xiàn)代碼如下
private JSONObject resolveApplicationJson(HttpServletRequest request) {
InputStream is = null;
String json = null;
try {
is = request.getInputStream();
json = IOUtils.toString(is, "UTF-8");
json=json.replaceAll("\\r|\n|\t","");
int index= json.indexOf("exp_Content");
int indexfirst=json.indexOf("{", index);
int indexlast=json.indexOf("}",index);
if (index!=-1 && indexlast !=-1 &&indexfirst !=-1) {
StringBuffer stringBuffer = new StringBuffer(json);
stringBuffer.delete(indexfirst,indexlast+1);
json=stringBuffer.toString();
}
} catch (IOException e) {
throw new RuntimeException("CANNOT get reader from request!", e);
} finally {
if (is != null) {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
try {
return new JSONObject(json);
} catch (JSONException e) {
throw new RuntimeException("CANOT CONVET JSON:[" + json + "] to JSONObject!", e);
}
}
多存在多個(gè)不符合規(guī)定的數(shù)據(jù)然后你要?jiǎng)h掉怎么操作呢？
這也很簡(jiǎn)單，如果你看了這一篇文章，你要更好的解決方式，期待一起探討，學(xué)習(xí)進(jìn)步(＾－＾)V

}解決方式如下：根據(jù)需要寫出正則表達(dá)式，再使用正則看看有幾個(gè)這樣的不需要的符號(hào)，然后循環(huán)遍歷幾次，之后找到這部分，最后刪除掉。
實(shí)現(xiàn)代碼如下
# 全局變量
private static String REGEX = "exp_[c,C]ontent";
# 方式方法
Pattern p = Pattern.compile(REGEX);
// 獲取 matcher 對(duì)象
Matcher m = p.matcher(JSON);
List<Integer> list = new ArrayList();
while(m.find()){
list.add(m.start());
}
int index=0;
int indexfirst=0;
int indexlast=0;
for (int j = 0; j < list.size(); j++) {
index=JSON.indexOf("exp_",indexlast);
indexfirst=JSON.indexOf("{", index);
indexlast=JSON.indexOf("}",index);
StringBuffer stringBuffer =null;
if (indexlast !=-1 &&indexfirst !=-1) {
stringBuffer = new StringBuffer(JSON);
stringBuffer.delete(indexfirst,indexlast+1);
}
JSON=stringBuffer.toString();
