Question

使用SecItemCopyMatching时，我得到了-34018。我没有找到任何文档这个错误代码的含义。也许有人可以帮助我。提前谢谢。

Answer 1

试试这个

 NSString *NSStringFromOSStatus(OSStatus errCode)
    {
        if (errCode == noErr)
            return @"noErr";
        char message[5] = {0};
        *(UInt32*) message = CFSwapInt32HostToBig(errCode);
        return [NSString stringWithCString:message encoding:NSASCIIStringEncoding];
    }

Answer 2

许多（全部？）安全框架错误代码在SecBase.h中定义，errSecMissingEntitlement = -34018, /* A required entitlement isn't present. */是一个头文件，是安全框架的一部分。您也可以在Apple's open-source Security framework。

中找到此文件

错误代码-34018因此被定义：

app.get("/start/:origin/:destination", function ( reqt, resp ) {
var origin = reqt.params.origin
var destination = reqt.params.destination
var url = 'http://localhost:5000/maps/' + origin + '/' + destination 

var rate;
var overallDis;
var aRoadDis;

var data;
http.get(url, res => {
    res.setEncoding('utf8')
    res.on('data', function(body){
        data = JSON.parse(body)
        overallDis = data["distance"]
        aRoadDis = data["ARoads"]
    })
})

var driver;
http.get("http://localhost:4000/lowestRate/", res => {
    res.setEncoding('utf8')
    res.on('data', function(body){
        driver = JSON.parse(body)
        rate = driver.rate
        console.log(rate)
    })

})

var totalPrice = 0
http.get("http://localhost:6000/surge/:" + rate + "/:" + overallDis + "/:" + aRoadDis, res => {
    // console.log(overallDis)
    // console.log(aRoadDis)
    // console.log(rate)
    res.setEncoding('utf8')
    res.on('data', function(body){
        console.log(body)
        totalPrice += parseInt(body)
    })
    console.log(totalPrice)
})

})
