#1

In post JSON string errors is JSONArray instead of String so you should first get errors from JSONObject then iterate over Array to get Strings:

在帖子中,JSON字符串错误是JSONArray而不是String,因此您应首先从JSONObject获取错误,然后迭代Array以获取字符串:

JSONArray arrArrors = jObject.getJSONArray("errors");
//iterate to arrArrors get all values
for(int i=0;i<arrArrors.length;i++) {
  String error = arrArrors.optString(i);
  Log.i("JSONDATA","error :: "+error);
}

errors is a JSONArray:

错误是JSONArray:

JSONArray errors = jObject.optJSONArray("errors");
for (int i = 0; i < errors.length(); i++) {
    String errorAtIndex = errors.optString(i);
}

From the documentation: optString(index)

来自文档:optString(index)

Returns the value at index if it exists, coercing it if necessary.

返回索引处的值(如果存在),必要时强制转换它。
