如何在不使用环境变量的情况下在.NET中传递帐户服务密钥？

Question

我需要创建一个DatastoreClient实例，其中以代码形式传递.json auth文件的路径。如何为数据存储区执行此操作？这是我要使用的代码-无法编译，因为我没有引用ToChannelCredentials（）方法的命名空间（我不确定在这种情况下是否可以使用它）：< / p>

  

How do I set credentials for google speech to text without setting environment variable?

library(dplyr)
library(tidyr)

num_date <- as.numeric(as.Date("2018-03-15"))

df <- df[,-ncol(df)]

df_join <- df %>%
  gather(Obs, value, 2:ncol(df)) %>%
  mutate(
    nr = as.numeric(gsub("[^\\d]", "", Obs, perl = TRUE))
  ) %>%
  group_by(subject_id, nr) %>%
  filter(!(is.na(value) | (grepl("_dq", Obs) & value == 0) | any(value[grepl("_date", Obs)] <= num_date))) %>%
  ungroup() %>%
  group_by(subject_id, Obs) %>%
  filter(!row_number() < (max(row_number() - 1))) %>%
  ungroup() %>%
  group_by(subject_id) %>%
  mutate(
    desired.average = mean(value[grepl("_date|_dq", Obs) == FALSE], na.rm = TRUE)
  ) %>%
  filter(!max(row_number()) == 3) %>%
  distinct(subject_id, desired.average)

df <- left_join(df, df_join)

我还将Cloud Storage用于我的项目，并使用Google演练中的解决方案来解决该问题。
