我正在使用BurntSushi库在我的GO应用程序中加载TOML配置文件。我已按照库上的说明编写结构和配置toml文件本身。我遇到了一些麻烦，我似乎无法找到问题的根源。
以下是详细信息：
的Structs：
package main
//ConfigurationParameters provides the struct to hold configuration parameters from config file
type ConfigurationParameters struct {
Title string
//serviceDiscovery captures configuration parameters needed for service discovery registration with Consul
ServiceDiscovery ConsulConf `toml:"ServiceDiscovery"`
//metadataReporting captures which metadata to be registered with service into consul for use during discovery
MetadataReporting MetaDataConf `toml:"MetadataReporting"`
//awsTagsToLabels captures the aws tags that should be added to reported metrics as Labels
AwsTagsToLabels LabelConf `toml:"AwsTagsToLabels"`
//collectors captures the list of collectors to use
Collectors CollectorConf `toml:"Collectors"`
//service captures agent related configurations
Service ServiceConf `toml:"Service"`
}
//ConsulConf captures configuration parameters needed for service discovery registration with Consul
type ConsulConf struct {
enabled bool
endpoint string
port int
datacenter string
serviceID string
}
//MetaDataConf captures which metadata to be registered with service into consul for use during discovery
type MetaDataConf struct {
enabled bool
awsregion string
}
//LabelConf captures the aws tags that should be added to reported metrics as Labels
type LabelConf struct {
enabled bool
refreshPeriod int
}
//CollectorConf captures the list of collectors to use
type CollectorConf struct {
goCollectionEnabled bool
exporterCollectionEnabled bool
wmiCollectionEnabled bool
agentCollectionEnabled bool
enabledCollectors string
metricMap []MetricMap
}
//MetricMap captures a mapping between one or more WMI metrics and the name it should be reported with
type MetricMap struct {
wmiMetricName []string
exportName string
dropMetric bool
computedMetric bool
computeLogic string
}
//ServiceConf captures agent related configurations
type ServiceConf struct {
listenIP string
listenPort int
metricPath string
collectionInterval int
serviceName string
}
和配置toml文件：
Title = "WMI Exporter Configuration"
[ServiceDiscovery]
enabled = true
endpoint = "my.consul.server"
port = 5500
datacenter = "ucm-west"
serviceID = "ucm.agent.wmiExporter"
[MetadataReporting]
enabled = true
awsregion = "us-west-2"
[AwsTagsToLabels]
enabled = true
refreshPeriod = 3600
[Collectors]
goCollectionEnabled = true
exporterCollectionEnabled = true
wmiCollectionEnabled = true
agentCollectionEnabled = false
enabledCollectors = "cpu,os"
[Collectors.MetricMap.0]
wmiMetricName = ["test"]
exportName = "export_test"
[Service]
listenPort = 9103
metricPath = "/metrics"
collectionInterval = 60
serviceName = "wmi_exporter"
读取配置文件的代码：
// InitializeFromConfig reads configuration parameters from configuration file and initializes this service
func InitializeFromConfig(configfile string) ConfigurationParameters {
conf := ConfigurationParameters{}
if configfile == "" {
return conf
}
_, err := toml.DecodeFile(configfile, &conf)
if err != nil {
log.Fatalf("Cannot parse configuration file at %s. Error=%s", configfile, err)
}
//at this point, conf is a fully loaded configuration now; now initialize everything from conf
return conf
}
我面临的问题是只有Title属性的值被映射到GO结构成员。所有其他配置保持未映射。查看github上BurntSushi和(Go) How to use toml files?的所有示例，我看不出我目前在代码中所做的任何差异。
我还使用了BurntSushi包中的tomlv验证器来查看TOML文件中的类型，我相信它们看起来是正确的。
数据类型：
Title String
ServiceDiscovery Hash
ServiceDiscovery.enabled Bool
ServiceDiscovery.endpoint String
ServiceDiscovery.port Integer
ServiceDiscovery.datacenter String
ServiceDiscovery.serviceID String
MetadataReporting Hash
MetadataReporting.enabled Bool
MetadataReporting.awsregion String
AwsTagsToLabels Hash
AwsTagsToLabels.enabled Bool
AwsTagsToLabels.refreshPeriod Integer
Collectors Hash
Collectors.goCollectionEnabled Bool
Collectors.exporterCollectionEnabled Bool
Collectors.wmiCollectionEnabled Bool
Collectors.agentCollectionEnabled Bool
Collectors.enabledCollectors String
Collectors.MetricMap.0 Hash
Collectors.MetricMap.0.wmiMetricName Array
Collectors.MetricMap.0.exportName String
Service Hash
Service.listenPort Integer
Service.metricPath String
Service.collectionInterval Integer
Service.serviceName String
我尝试调试BurntSushi包代码，但它不是很有帮助（Delve调试器无法显示该包中的某些变量，并且似乎在该包中的行之间随机跳转）。
关于我可能做错的任何帮助或指示？
感谢。
答案 0 :(得分：1)
您需要导出要将#include <stdio.h>
#include <string.h>
int main()
{
char email[40], first[20],last[20],host[30],name[40];
int firstDot,atSymbol;
int i;
int length;
char *token;
printf("Enter the email= ");
gets(email);
length = strlen(email);
for(i=0;i<length;i++){
if(email[i]=='.')
{
firstDot = i;
}
else if(email[i]=='@')
{
atSymbol = i;
}
}
strncpy(name,email,atSymbol);
name[atSymbol]= '\0';
token = strtok(name, ".");
/* walk through other tokens */
while( token != NULL )
{
printf( "%s\n", token );
token = strtok(NULL, ".");
}
strncpy(host,email+atSymbol,length-atSymbol);
host[length-atSymbol] = '\0';
puts(host);
}
解组的任何字段，包括子字段：
BurntSushi/toml此外，我不确定这个//ConfigurationParameters provides the struct to hold configuration parameters from config file
type ConfigurationParameters struct {
Title string
//serviceDiscovery captures configuration parameters needed for service discovery registration with Consul
ServiceDiscovery ConsulConf `toml:"ServiceDiscovery"`
//metadataReporting captures which metadata to be registered with service into consul for use during discovery
MetadataReporting MetaDataConf `toml:"MetadataReporting"`
//awsTagsToLabels captures the aws tags that should be added to reported metrics as Labels
AwsTagsToLabels LabelConf `toml:"AwsTagsToLabels"`
//collectors captures the list of collectors to use
Collectors CollectorConf `toml:"Collectors"`
//service captures agent related configurations
Service ServiceConf `toml:"Service"`
}
//ConsulConf captures configuration parameters needed for service discovery registration with Consul
type ConsulConf struct {
Enabled bool
Endpoint string
Port int
Datacenter string
ServiceID string
}
//MetaDataConf captures which metadata to be registered with service into consul for use during discovery
type MetaDataConf struct {
Enabled bool
Awsregion string
}
//LabelConf captures the aws tags that should be added to reported metrics as Labels
type LabelConf struct {
Enabled bool
RefreshPeriod int
}
//CollectorConf captures the list of collectors to use
type CollectorConf struct {
GoCollectionEnabled bool
ExporterCollectionEnabled bool
WmiCollectionEnabled bool
AgentCollectionEnabled bool
EnabledCollectors string
MetricMap []MetricMap
}
//MetricMap captures a mapping between one or more WMI metrics and the name it should be reported with
type MetricMap struct {
WmiMetricName []string
ExportName string
DropMetric bool
ComputedMetric bool
ComputeLogic string
}
//ServiceConf captures agent related configurations
type ServiceConf struct {
ListenIP string
ListenPort int
MetricPath string
CollectionInterval int
ServiceName string
}
语法应该表示什么，而是将您的toml值解组到Collectors.MetricMap.0字段中
你想要做的是这样的事情：
[]MetricMap
