【问题描述】：

我需要向 api 发送 cURL 请求，但我没有正确理解文档。第一次使用 cURL。这是发送请求的详细信息。

# Steps to send request
# First get JSON Web Token
# Please get your Client Id and Client Secret from https://dashboard.groupdocs.cloud/applications.
# Kindly place Client Id in "client_id" and Client Secret in "client_secret" argument.
curl -v "https://api.groupdocs.cloud/connect/token" \
-X POST \
-d "grant_type#client_credentials&#x26;client_id#xxxx&#x26;client_secret#xxxx" \
-H "Content-Type: application/x-www-form-urlencoded" \
-H "Accept: application/json"
  
$ cURL example to join several documents into one
curl -v "https://api.groupdocs.cloud/v1.0/parser/text" \
-X POST \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-H "Authorization: Bearer 
<jwt token>" \
-d "{
        "FileInfo": {
            "FilePath": "words\docx\document.docx",
    }
}"

这就是响应的方式

{
    "text": "First Page\r\r\f"
}

【解决方案1】：

Curl 只是一个发送请求的工具你可以在颤振中对 http 包做同样的事情你的第一个 curl 请求相当于这个

var headers = {
  'Content-Type': 'application/x-www-form-urlencoded'
};
var request = http.Request('POST', Uri.parse('https://api.groupdocs.cloud/connect/token'));
request.bodyFields = {
  'grant_type': '',
  'client_id': '',
  'client_secret': ''
};
request.headers.addAll(headers);

http.StreamedResponse response = await request.send();

if (response.statusCode == 200) {
  print(await response.stream.bytesToString());
}
else {
  print(response.reasonPhrase);
}

第二次请求

var headers = {
  'Authorization': 'Bearer <jwt token>',
  'Content-Type': 'application/json'
};
var request = http.Request('POST', Uri.parse('https://api.groupdocs.cloud/v1.0/parser/text'));
request.body = json.encode({
  "FileInfo": {
    "FilePath": "words\\docx\\document.docx"
  }
});
request.headers.addAll(headers);

http.StreamedResponse response = await request.send();

if (response.statusCode == 200) {
  print(await response.stream.bytesToString());
}
else {
  print(response.reasonPhrase);
}

了解http请求，使用postman之类的工具习惯它，然后使用http发送这些请求
