您可以使用以下查询来获取文件内容,同时获取该文件的最后一次提交。这样,您还可以根据需要获得 pushedAt、committedDate 和 authorDate 字段:
{
repository(owner: "torvalds", name: "linux") {
content: object(expression: "master:Makefile") {
... on Blob {
text
}
}
info: ref(qualifiedName: "master") {
target {
... on Commit {
history(first: 1, path: "Makefile") {
nodes {
author {
email
}
message
pushedDate
committedDate
authoredDate
}
pageInfo {
endCursor
}
totalCount
}
}
}
}
}
}
请注意,我们还需要获取 endCursor 字段才能获取文件的第一次提交(获取文件创建日期)
例如在Linux repo 上,它给出的Makefile 文件:
"pageInfo": {
"endCursor": "b29482fde649c72441d5478a4ea2c52c56d97a5e 0"
}
"totalCount": 1806
所以这个文件有 1806 次提交
为了获得第一次提交,引用最后一个游标的查询将是b29482fde649c72441d5478a4ea2c52c56d97a5e 1804:
{
repository(owner: "torvalds", name: "linux") {
info: ref(qualifiedName: "master") {
target {
... on Commit {
history(first: 1, after:"b29482fde649c72441d5478a4ea2c52c56d97a5e 1804", path: "Makefile") {
nodes {
author {
email
}
message
pushedDate
committedDate
authoredDate
}
}
}
}
}
}
}
返回此文件的第一次提交。
我没有关于光标字符串格式"b29482fde649c72441d5478a4ea2c52c56d97a5e 1804" 的任何来源,我已经使用其他一些包含超过 1000 次提交的文件的存储库进行了测试,似乎它的格式总是如下:
<static hash> <incremented_number>
避免迭代所有提交,以防有超过 100 个提交引用您的文件
这是在javascript 中使用graphql.js 的实现:
const graphql = require('graphql.js');
const token = "YOUR_TOKEN";
const queryVars = { name: "linux", owner: "torvalds" };
const file = "Makefile";
const branch = "master";
var graph = graphql("https://api.github.com/graphql", {
headers: {
"Authorization": `Bearer ${token}`,
'User-Agent': 'My Application'
},
asJSON: true
});
graph(`
query ($name: String!, $owner: String!){
repository(owner: $owner, name: $name) {
content: object(expression: "${branch}:${file}") {
... on Blob {
text
}
}
info: ref(qualifiedName: "${branch}") {
target {
... on Commit {
history(first: 1, path: "${file}") {
nodes {
author {
email
}
message
pushedDate
committedDate
authoredDate
}
pageInfo {
endCursor
}
totalCount
}
}
}
}
}
}
`)(queryVars).then(function(response) {
console.log(JSON.stringify(response, null, 2));
var totalCount = response.repository.info.target.history.totalCount;
if (totalCount > 1) {
var cursorPrefix = response.repository.info.target.history.pageInfo.endCursor.split(" ")[0];
var nextCursor = `${cursorPrefix} ${totalCount-2}`;
console.log(`total count : ${totalCount}`);
console.log(`cursorPrefix : ${cursorPrefix}`);
console.log(`get element after cursor : ${nextCursor}`);
graph(`
query ($name: String!, $owner: String!){
repository(owner: $owner, name: $name) {

history(first: 1, after:"${nextCursor}", path: "${file}") {
nodes {

}
}
}
}
}
}`)(queryVars).then(function(response) {
console.log("first commit info");
console.log(JSON.stringify(response, null, 2));
}).catch(function(error) {
console.log(error);
});
}
}).catch(function(error) {
console.log(error);
});
