Question

我正在尝试在JS应用程序中对GitHub v4 API执行GraphQL查询，但我遇到了“JSON问题”错误。所以我试图用cURL来做，但它似乎有一个我看不到的问题。


    curl -H "Authorization: token bearer" -H  "Content-Type:application/json" -X POST -d '{ "query": "query {
      viewer {                                                             
        watching(first: 3, orderBy: {field: UPDATED_AT, direction: DESC}) {
          nodes {                                                                                            
            refs(refPrefix: \"refs/heads/\", orderBy: {direction: DESC, field: TAG_COMMIT_DATE}, last: 100) {
              nodes {   
                target {         
                  ... on Commit {       
                    history(first: 10) {
                      ...CommitFragment
                    }
                  }
                }
              }
            }
          }
        }
      }          
      rateLimit {
        limit
        cost     
        remaining
        resetAt
      }
    }

    fragment CommitFragment on CommitHistoryConnection {
      nodes {  
        message 
        author {
          name               
          avatarUrl(size: 30)
        }
      }
    }

我想提一下，该请求正在github.com/v4/explorer/网站上运行。我已经逃脱了报价......

问题是查询是JSON字符串化的，在您的请求中，您在JSON字符串字段query中添加了不允许的新行：

curl -H "Authorization: token YOUR_TOKEN" \
     -H  "Content-Type:application/json" \
     -d '{ 
          "query": "{ viewer { watching(first: 3, orderBy: {field: UPDATED_AT, direction: DESC}) { nodes { refs(refPrefix: \"refs/heads/\", orderBy: {direction: DESC, field: TAG_COMMIT_DATE}, last: 100) { nodes { target { ... on Commit { history(first: 10) { ...CommitFragment } }}}}}}} rateLimit { limit cost remaining resetAt}}fragment CommitFragment on CommitHistoryConnection { nodes { message author { name avatarUrl(size: 30) } } }"
      }' https://api.github.com/graphql

如果使用Javascript，则使用XMLHttpRequest：

var http = new XMLHttpRequest();
var url = "https://api.github.com/graphql";
http.open("POST", url, true);

http.setRequestHeader("Content-type", "application/json");
http.setRequestHeader("Authorization", "token YOUR_TOKEN");

http.onreadystatechange = function() {
    if (http.readyState == 4 && http.status == 200) {
        alert(http.responseText);
    }
}

http.send(JSON.stringify({
    "query": '{ viewer { watching(first: 3, orderBy: {field: UPDATED_AT, direction: DESC}) { nodes { refs(refPrefix: "refs/heads/", orderBy: {direction: DESC, field: TAG_COMMIT_DATE}, last: 100) { nodes { target { ... on Commit { history(first: 10) { ...CommitFragment } }}}}}}} rateLimit { limit cost remaining resetAt}}fragment CommitFragment on CommitHistoryConnection { nodes { message author { name avatarUrl(size: 30) } } }'
}));

您还可以使用apollo-client和graphql.js
