我使用的是西風API和它的返回我包含像這樣的JSON對象JSON數組...如何僅讀取json響應中的一個值?
{
"executions": [
{
"id": 24,
"cycleId": 13,
"cycleName": "CLONE - Audit Test Cycle 2",
"issueKey": "ZFJ-2",
"projectKey": "ZFJ",
"project": "ZFJ",
"priority": "Major",
"component": "c1",
"versionId": 10000,
"version": "v1",
"status": {
"id": 2,
"name": "FAIL",
"description": "Test was executed and failed.",
"color": "#CC3300",
"type": 0
},
"executedOn": "18/Oct/13",
"creationDate": "18/Oct/13",
"executedBy": "admin",
"executedByUserName": "admin"
},
{...},
{
"id": 1,
"cycleId": 1,
"cycleName": "Audit Test Cycle",
"issueKey": "ZFJ-2",
"projectKey": "ZFJ",
"project": "ZFJ",
"priority": "Major",
"component": "c1",
"versionId": 10000,
"version": "v1",
"status": {
"id": 1,
"name": "PASS",
"description": "Test was executed and passed successfully.",
"color": "#75B000",
"type": 0
},
"executedOn": "4/Oct/13",
"creationDate": "4/Oct/13",
"executedBy": "admin",
"executedByUserName": "admin"
}
]
本來我是用org.json解析JSON數組,但它似乎很慢,我當我只解析約200個json對象時。我需要從每個對象中唯一需要的是「id」,所以我想通過掃描每個json對象中的「id」來解析文檔,而不是使用org.json來解析整個json響應。
這會提高我的解析性能而不是使用org.json嗎?如何在沒有解析器的情況下掃描json響應?我假設json響應仍然是一行文本,解析器是檢索鍵和值的東西。
是否有更好的選擇我所建議的?更高效的解析器? org.json的性能與其他解析器相比如何?
你不需要自己寫這個,它已經存在。看看這個例子http://www.ngdata.com/parsing-a-large-json-file-efficiently-and-easily/ – Dici
